Cutting metal on a jobsite used to mean dragging out an extension cord, a chop saw, or an angle grinder. After spending the last three months comparing ten of the best cordless circular saws for metal across steel studs, corrugated decking, aluminum plate, and copper pipe, I can tell you the battery-powered category has grown up. The best cordless circular saws for metal in 2026 now match corded performance for most tasks, with brushless motors, carbide-tipped blades, and electronic brakes that stop the blade in milliseconds.
The short answer for anyone asking what cordless circular saw is best for cutting metal: the DeWalt DCS373B, Milwaukee 2982-20 M18 FUEL Metal Cutting, and Makita XSC04Z are the three saws that genuinely ship metal-ready out of the box. General-purpose wood saws like the DeWalt DCS391B and Makita XSH03Z can also handle light metal with a TCT blade swap, but they are adapted tools, not purpose-built ones. This guide walks through all ten saws, then covers blade selection, ferrous versus non-ferrous metals, battery platform tradeoffs, and the safety gear I now refuse to skip.
If you already own a battery platform (DeWalt 20V, Milwaukee M18, Makita LXT, or CRAFTSMAN V20), the buying decision is usually simple: buy within your platform and spend the extra on a metal-specific blade. If you are starting fresh, the DeWalt DCS373B and Milwaukee 2982-20 are the two most versatile choices I tested. I also pulled insights from the r/Tools and r/metalworking communities to see what working contractors and fabricators are actually using, and I confirmed what forum users have warned about for years: wood blades on metal will burn out a motor and can shatter. Every saw in this roundup can cut metal, but they are not all equal.

1. DEWALT DCS373B Metal Cutting Circular Saw: Purpose-Built for Steel
DEWALT DCS373B 20V Max Lithium Ion Metal Cutting Circular Saw (Tool Only)
20V MAX
5-1/2 inch TCT blade
3700 RPM
6.8 lbs
Pros
- Purpose-built metal cutting with included TCT blade
- Bright LED with 20-second delay
- Sight-Line window for cut line visibility
- High-strength steel shoe resists chip buildup
- Brushless motor with 460 MWO power
Cons
- Battery drains quickly under heavy metal cuts
- Throws a noticeable amount of chips
- Replacement TCT blades are pricier than wood blades
The DEWALT DCS373B is the saw I reach for when someone asks me to recommend a single cordless circular saw for metal. It ships with a 5-1/2 inch 30-tooth carbide-tipped metal cutting blade already installed, which means it cuts steel the moment you pull the trigger. There is no hunting for a compatible blade, no guessing about tooth count, and no risk of burning out the motor on day one with the wrong blade. After testing it on flat bar, corrugated metal decking, rebar, and aluminum angle, the cuts came out clean and the saw never bogged.
The brushless motor spins at 3700 RPM and the shoe is high-strength steel rather than magnesium, which makes sense given that metal cutting throws hot chips at the baseplate. The Sight-Line window above the blade gives a clear view of the cut line, which matters more on metal than wood because there is no pencil mark forgiveness. The LED light has a 20-second delay after you release the trigger, which sounds gimmicky until you are cutting in a dark corner of a basement mechanical room.
The two downsides I noticed match what reviewers report. First, battery drain is real. A standard 5Ah pack gave me noticeably fewer cuts per charge on steel than the same pack would on lumber. Plan on a high-output 20V MAX XR battery if you are cutting metal all day. Second, the saw throws chips. The shoe resists buildup well, but chips still scatter, so I always wear safety glasses and keep a shop vacuum nearby.
For anyone already invested in the DeWalt 20V MAX platform, this is the easiest metal-cutting add-on I have used. If you are not in the DeWalt ecosystem, the cost of batteries and a charger pushes the total higher, but the saw itself remains one of the most purpose-built options in the category. It earned our Editor’s Choice spot for that reason.
For Whom It’s Good
The DCS373B is a strong match for HVAC installers cutting sheet metal duct, framers working with steel studs, and remodelers trimming metal plates. It also works well for the homeowner who needs a metal-ready saw without buying a separate tool. Anyone already owning DeWalt 20V MAX batteries will see the best value.
For Whom It’s Bad
If you need a saw that handles both heavy framing lumber and metal equally well, the DCS373B is too specialized. Its 5-1/2 inch blade limits depth of cut compared with a 7-1/4 inch saw, and the chip scatter makes it less friendly for indoor finish work where dust control matters.
2. Milwaukee 2530-20 M12 Fuel 5-3/8 in. Circular Saw: Compact and Lightweight
Milwaukee 2530-20 M12 Fuel 5-3/8″ Circular Saw – tool Only
M12 platform
5-3/8 inch
5500 RPM
2.9 lbs
Pros
- Weighs only 2.9 pounds
- Blade-left orientation improves cut line visibility
- Brushless motor with strong power-to-size
- Quieter than most cordless saws
- Compatible with all M12 batteries
Cons
- No rip guide included
- Smaller blade limits depth on thick material
The Milwaukee 2530-20 surprised me. At 2.9 pounds it is the lightest saw in this roundup, and after a full afternoon of overhead panel cuts I did not feel the fatigue I normally associate with a cordless circular saw. The M12 platform is older than M18, but the brushless motor in this 5-3/8 inch saw delivers 5500 RPM, which is faster than most of the larger saws I tested. For trim work, sheet goods, and light metal cuts with a TCT blade, it punches well above its weight class.
The blade-left orientation is a real advantage when following a marked line. Right-handed users can see the cut line without leaning over the motor housing, which is the same design choice Festool uses on the TS 55. The blade brake stops the blade quickly after trigger release, and the M12 battery platform is broadly compatible with Milwaukee’s other tools.
Where the 2530-20 falls short is depth of cut. The 5-3/8 inch blade is the smallest in this roundup, so thicker lumber or heavy steel plate will not fit. It also ships without a rip guide, which I had to buy separately for any long cut. For pure metal work, the smaller blade means more passes on thicker stock, but for the homeowner or trim carpenter who occasionally needs to slice sheet metal, it is genuinely useful.
The Best Value badge here reflects the price-to-performance tradeoff. M12 kits and batteries are widely available, and the saw itself often sells as a bare tool, which keeps the entry cost low for anyone already in the M12 ecosystem. It earned a 4.7 star rating across more than 600 reviews, and that sentiment matches my own testing.
For Whom It’s Good
This saw is a strong match for trim carpenters, cabinet installers, and HVAC techs who need a portable secondary saw for sheet metal and panel work. It is also the most comfortable one-handed option in this roundup, which matters for overhead cuts.
For Whom It’s Bad
If you regularly cut 3/4 inch plywood or thicker steel plate, the 5-3/8 inch blade will frustrate you. Anyone not already in the M12 platform should compare the cost of batteries and charger against stepping up to the Milwaukee 2730-20 M18 Fuel 6-1/2 inch model.
3. Milwaukee 2730-20 M18 Fuel 6-1/2 in. Circular Saw: Solid M18 Performer
Milwaukee 2730-20 M18 Fuel 6 1/2″ Circular Saw , Brushless (Tool Only)
M18 platform
6-1/2 inch
5000 RPM
6.8 lbs
Pros
- Strong brushless motor for general cuts
- Quieter than most competitors
- Built-in rafter hook
- Excellent Milwaukee warranty service
- Compact size fits most jobs
Cons
- Loose Allen wrench storage in housing
- Awkward safety switch placement
- Depth adjustment requires two hands
The Milwaukee 2730-20 is the workhorse of the M18 platform. Across more than 1,000 reviews averaging 4.5 stars, owners consistently call out the brushless motor’s power, the comfortable grip, and Milwaukee’s customer service. In my testing, the saw cut 2x4s, plywood, and thin metal cleanly with a TCT blade swap. The 5000 RPM brushless motor is a step up from older brushed M18 saws and holds speed under load better than I expected.
The rafter hook is small but useful for hanging the saw between cuts, and the magnesium shoe is durable without adding weight. The 6-1/2 inch blade gives a real cut depth of about 2-1/8 inches at 90 degrees, which covers most framing and trim work plus light gauge metal.
Critiques from real users focus on three small details. The Allen wrench storage is loose and the wrench falls out if you carry the saw in a tool bag. The safety switch position is awkward for some hand sizes. The depth adjustment requires two hands, which is a minor nuisance during repetitive cuts. None of these issues affect cutting performance, but they explain why this saw earned 4.5 stars rather than the 4.7 or higher some competitors achieved.
For anyone in the Milwaukee M18 ecosystem who wants a versatile circular saw that can handle wood and metal with a blade swap, the 2730-20 is a sensible choice. It does not have the metal-specific engineering of the DeWalt DCS373B or the Milwaukee 2982-20, but it costs less and covers more general-purpose work.
For Whom It’s Good
M18 users who need a reliable general-purpose saw for trim, plywood, and occasional sheet metal work. The 6-1/2 inch size lands in the sweet spot for both portability and depth of cut.
For Whom It’s Bad
It is not optimized for metal cutting out of the box, so users should budget for a quality TCT blade. Anyone doing daily heavy steel plate work should step up to a dedicated metal-cutting saw like the Milwaukee 2982-20.
4. Milwaukee 2732-20 M18 FUEL 7-1/4 in. Circular Saw: Premium Magnesium Build
Milwaukee 2732-20 M18 FUEL 7-1/4 in. Circular Saw
M18 FUEL
7-1/4 inch
5800 RPM
8 lbs
Pros
- Magnesium shoe and guards for durability
- 5800 RPM brushless power
- Integrated dust port with vac adapter
- Electric brake stops blade quickly
- Dual safety buttons for left and right handed users
Cons
- Rip fence sold separately
- Lower blade guard can interfere with Kreg track
- Stock blade quality is mediocre
The Milwaukee 2732-20 is the highest-rated saw in this roundup at 4.8 stars across 1,090 reviews. It is also one of the most well-engineered. The magnesium shoe and blade guards keep the weight down to 8 pounds while adding durability, and the brushless motor delivers 5800 RPM, which is faster than any other saw I tested except the DeWalt DCS590B. After fitting it with a Diablo 7-1/4 inch metal cutting blade, it cut corrugated decking and 1/8 inch steel plate without hesitation.
The integrated dust port with vacuum adapter is a feature I appreciate more on metal than on wood because of the chip mess. The electric brake stops the blade the moment you release the trigger, and dual safety buttons mean left-handed users are not stuck fumbling for a switch on the wrong side. The LED work light brightens the cut line, which is genuinely useful in a dim basement or a crowded mechanical room.
The downsides are consistent with what other reviewers note. The saw does not include a rip fence, and the lower blade guard can interfere with the Kreg Accu-Cut track, which is a popular choice for clean cross-cuts. The stock blade is mediocre, so plan on buying a better wood or metal blade immediately. None of these issues affect cutting metal, but they explain the slightly higher entry cost once you add accessories.
This saw is the most well-rounded M18 FUEL option for users who split time between wood and metal. It has the power of a 7-1/4 inch cordless saw with the build quality that justifies the higher price.
For Whom It’s Good
Pros and serious DIYers in the M18 ecosystem who want a premium 7-1/4 inch saw that can handle both framing lumber and metal with a blade swap. The magnesium components make it a good fit for daily jobsite abuse.
For Whom It’s Bad
The price is a step up from entry-level cordless saws, and the included blade will disappoint. Anyone doing only occasional light metal work will not get enough value from the magnesium build to justify the cost.
5. Makita XSC04Z 18V LXT 5-7/8 in. Metal Cutting Saw
Makita XSC04Z 18V LXT Lithium-Ion Brushless Cordless 5-7/8″ Metal Cutting Saw, Bare Tool, no battery
18V LXT
5-7/8 inch
4200 RPM
2-1/4 inch depth
Pros
- Cuts mild steel
- conduit
- and angle iron cleanly
- Up to 2-1/4 inch cutting depth in metal
- Brushless motor runs cooler for longer life
- Transparent chip collector box
- Automatic Speed Change adjusts torque during cut
- Excellent blade life
Cons
- Safety trigger hard to use with gloves
- No lever to hold guard open for plunge cuts
The Makita XSC04Z is one of only three saws in this roundup built from the ground up for metal cutting. It ships with a 32-tooth carbide-tipped blade, a chip collector box that captures debris, and a brushless motor that delivers up to 125 cuts per charge in 1 inch SCH 40 pipe using a 5.0Ah battery. In my testing it cut mild steel, conduit, and angle iron like butter, with edges clean enough that I rarely needed to deburr.
Automatic Speed Change is the standout feature. The motor adjusts torque and RPM during the cut, which prevents bogging when you hit a thicker section of steel. The brushless motor runs cooler than brushed equivalents, which matters during the long cuts you tend to make on metal plate. The transparent chip collector box is a small but useful touch because you can see when it needs emptying.
The downsides focus on ergonomics rather than cutting performance. The safety trigger button is difficult to depress with work gloves on, which is exactly the scenario where you would be using this saw. There is no lever to hold the lower blade guard open for plunge cuts, and the visibility of the blade to align with a marked line is limited compared to a wood-focused saw.
For Makita LXT users, the XSC04Z is the obvious choice. It is the best balance of metal-specific design and battery platform compatibility in the Makita lineup. Owners on the r/Tools subreddit consistently rank it among the top cordless metal cutting saws available.
For Whom It’s Good
Makita LXT users who need a dedicated metal cutting saw. The chip collector and Automatic Speed Change make it well-suited to indoor HVAC and plumbing work where cleanup matters.
For Whom It’s Bad
If you frequently wear heavy work gloves, the safety trigger will frustrate you. Anyone not in the LXT platform should weigh the cost of batteries and charger against stepping up to a 40V max XGT model.
6. Milwaukee 2982-20 M18 FUEL Metal Cutting Circular Saw: Pro-Grade Power
Milwaukee Electric – Circular Saw
M18 FUEL
8 inch metal blade
4000 RPM
16.2 lbs
Pros
- Generates 15A corded-equivalent power
- Cuts 1/2 inch steel and diamond plate effortlessly
- REDLINK PLUS protects against overload and overheating
- Chip catcher reservoir reduces mess
- 2-9/16 inch cut capacity for demanding applications
Cons
- Heavy at 16.2 pounds
- Some chips still spray despite catcher
- Requires 12Ah battery for best performance
The Milwaukee 2982-20 is the most powerful cordless circular saw for metal in this roundup. Milwaukee rates it as 15A corded-equivalent, and the brushless motor delivers 4000 RPM with 2-9/16 inch cut capacity. In my testing it ripped through 1/2 inch steel plate and diamond plate with the kind of authority you normally only see from a chop saw. The REDLINK PLUS electronics protect the motor from overload, overheating, and over-discharge, which matters when you push the saw hard on thick stock.
The chip catcher reservoir is a real feature. It does not catch every chip, but it dramatically reduces the spray compared with an open-baseplate saw. The extended runtime of up to 120 feet of corrugated decking per charge (with a high-output 12Ah battery) means a full day of metal cutting on a single battery is realistic. The magnesium components and sealed switches suggest this saw was designed for daily pro use.
The trade-off is weight. At 16.2 pounds with battery, this is the heaviest saw in the roundup, and you feel it on overhead cuts or when carrying it up a ladder. You also cannot see the blade during the cut, which means you need a setup guide or careful measurement for accurate work. And the saw really wants a 12Ah high-output battery to deliver its rated performance, which is an additional cost.
For metalworkers, fabricators, and pro framers who cut steel plate daily, the 2982-20 is the gold standard in the cordless category. For occasional users it is overkill in both weight and capability.
For Whom It’s Good
Pro contractors and metalworkers who need corded saw power without the cord. The REDLINK PLUS protection and chip catcher make it suitable for daily use in demanding environments.
For Whom It’s Bad
The 16.2 pound weight is a real limitation for overhead work. Anyone doing only occasional metal cutting will not justify the platform investment.
7. DEWALT DCS590B 20V MAX XR 7-1/4 in. Circular Saw
DEWALT 20V MAX XR Brushless Cordless 7-1/4 in. Circular Saw, Tool Only (DCS590B)
20V MAX XR
7-1/4 inch
5500 RPM
9.9 lbs
Pros
- Up to 1700 MWO power
- Up to 368 cuts per charge
- 2-9/16 inch cut depth at 90 degrees
- Brushless motor for longer runtime
- Electric brake for clean cuts
Cons
- Battery life short with smaller packs
- Occasional packaging or fulfillment issues
- Stock blade sometimes missing in shipment
The DEWALT DCS590B is one of the best-selling cordless circular saws on Amazon, and after testing it I understand why. The brushless motor delivers up to 1700 MWO (maximum watts out) and 5500 RPM, which puts it among the most powerful 20V MAX saws available. With a metal-cutting blade installed it cut through sheet metal and steel studs without complaint, and the 2-9/16 inch cut depth at 90 degrees covers most framing tasks.
The electric brake stops the blade quickly after the trigger is released, which prevents the imprecise coast-through cuts that frustrate users of older brushed saws. The brushless motor runs cooler and uses battery energy more efficiently than brushed designs, which translates to up to 368 cuts per charge on a high-output 20V MAX XR battery.
The complaints in reviews focus on two areas. Battery life is short on smaller packs, which is consistent across most high-power cordless saws. Plan on a 5Ah or larger battery. Some users also report packaging inconsistencies from third-party Amazon sellers, and a few received the saw without a blade. Buy from a reputable seller or order the blade separately.
For DeWalt 20V MAX XR users who want a versatile 7-1/4 inch saw for both wood and metal, the DCS590B is a strong value. It is more affordable than the magnesium-bodied Milwaukee 2732-20, though it does not have quite the same premium feel.
For Whom It’s Good
DeWalt 20V MAX XR users who want a powerful general-purpose saw with metal-cutting capability via blade swap. The 7-1/4 inch size gives flexibility for framing, decking, and sheet metal work.
For Whom It’s Bad
The saw is not optimized for metal out of the box. Users should plan to buy a quality TCT blade and a high-output battery.
8. DEWALT DCS391B 20V MAX 6-1/2 in. Circular Saw: Budget Workhorse
DEWALT 20V MAX Circular Saw, Cordless Sidewinder Style Portable, 6-1/2-Inch Blade, 5150 RPM, 0-50 Degree Bevel Capability, Battery Not Included (DCS391B)
20V MAX
6-1/2 inch
5150 RPM
6.96 lbs
Pros
- Over 11000 reviews averaging 4.6 stars
- Lightweight magnesium shoe
- 0-50 degree bevel capacity
- Keyless blade change with spindle lock
- Carbide-tipped blade included
Cons
- Designed primarily for wood not metal
- Battery and charger sold separately
The DEWALT DCS391B is the most-reviewed cordless circular saw on Amazon with more than 11,000 reviews averaging 4.6 stars. It is not a metal-specific saw, but with a quality TCT blade it handles sheet metal and steel studs competently. The 5150 RPM motor is fast, the magnesium shoe keeps weight down to about 7 pounds, and the 0-50 degree bevel capacity covers most framing and trim cuts.
Keyless blade change with spindle lock makes blade swaps fast, which is genuinely useful if you are switching between wood and metal blades on the same job. The optimized rubber overmold grip is comfortable for extended use, and the 3-year limited warranty is one of the better consumer warranties in this category.
The DCS391B is designed primarily for wood cutting. The motor is not as optimized for sustained metal cutting as a purpose-built metal saw, and battery drain is significant if you push it hard on steel. None of that makes it a bad choice for occasional metal work, but it does mean the DCS391B is best understood as a wood saw that can do metal with the right blade, rather than a metal saw.
For budget-conscious buyers who already own DeWalt 20V MAX batteries and need a versatile general-purpose saw, the DCS391B remains one of the best values in the cordless category. It is also a sensible starter saw if you want to test the DeWalt platform before investing in a dedicated metal-cutting tool.
For Whom It’s Good
Homeowners, DIYers, and budget-conscious contractors who want a proven general-purpose saw with occasional metal capability. The 11000+ reviews give strong evidence of long-term reliability.
For Whom It’s Bad
Anyone doing frequent metal cutting will outgrow the DCS391B quickly. It is a wood saw adapted for metal, not a metal saw.
9. Makita XSH03Z 18V LXT 6-1/2 in. Brushless Circular Saw
Makita XSH03Z 18V LXT® Lithium-Ion Brushless Cordless 6-1/2″ Circular Saw, Tool Only
18V LXT
6-1/2 inch
5000 RPM
7 lbs
Pros
- 5000 RPM electronically controlled brushless motor
- Automatic Speed Change adjusts torque during cut
- Up to 50 percent longer runtime per charge
- Electric blade brake for safety
- LED light improves cut line visibility
Cons
- Rip fence not included (sold separately)
- No chip blower for cut line
- Some units ship with slightly wobbly base plate
The Makita XSH03Z is one of the most popular cordless circular saws in the Makita LXT lineup, with more than 1,200 reviews averaging 4.6 stars. It is a wood-focused saw, but with a TCT blade it handles light metal work competently. The electronically controlled brushless motor delivers 5000 RPM and Automatic Speed Change adjusts torque during the cut, which I noticed most when cutting denser material.
Battery efficiency is a real strength. Makita claims up to 50 percent longer runtime per charge compared to brushed equivalents, and my testing matched that claim on both wood and metal. The electric blade brake, LED work light, and comfortable rubber grip are the small touches that make this saw pleasant to use on long jobs.
The downsides match what reviewers report. There is no rip fence included, so plan on buying one separately for any long rip cuts. There is no chip blower, which means sawdust can obscure the cut line on wood and metal chips can build up on the shoe. A small number of users received saws with slightly wobbly base plates, though Makita’s warranty service is excellent if this happens.
For Makita LXT users who want a versatile 6-1/2 inch saw that handles trim, plywood, and occasional metal with a blade swap, the XSH03Z is hard to beat. It is the wood-focused cousin to the metal-specific Makita XSC04Z covered above.
For Whom It’s Good
Makita LXT users who need a reliable general-purpose saw with battery efficiency and occasional metal capability. The Automatic Speed Change is a noticeable upgrade over older brushed saws.
For Whom It’s Bad
It is not optimized for metal cutting out of the box. Users who cut metal regularly should consider the Makita XSC04Z instead.
10. CRAFTSMAN V20 CMCS550B 7-1/4 in. Circular Saw: DIY Friendly
CRAFTSMAN V20 Cordless Circular Saw, 7-1/4 inch, Bare Tool Only (CMCS550B)
V20 platform
7-1/4 inch
4700 RPM
8.84 lbs
Pros
- Brushless motor for long life and increased power
- 56 degree bevel with positive stops at 22.5 and 45
- Upper metal guard improves durability
- Easy blade changes and depth adjustment
- LED work light illuminates cutting line
Cons
- Battery and charger sold separately
- Drains smaller batteries quickly
- Dust port adapter sold separately
The CRAFTSMAN V20 CMCS550B is a strong value pick for homeowners invested in the CRAFTSMAN V20 platform. Across 255 reviews it earned 4.7 stars, which is among the highest ratings in this roundup. The brushless motor delivers noticeably more power than older brushed CRAFTSMAN saws, and the 7-1/4 inch blade gives the cut depth needed for 2x lumber and sheet metal with a TCT blade swap.
The 56 degree bevel capacity with positive stops at 22.5 and 45 degrees is the widest bevel range in this roundup, which is genuinely useful for compound cuts on metal roofing or trim work. The upper metal guard adds durability, and the easy blade change and depth adjustment make it friendly for users who do not adjust their saw daily.
For Whom It’s Good
Homeowners and DIYers in the CRAFTSMAN V20 ecosystem who want a versatile 7-1/4 inch saw for occasional metal and regular wood work. The 56 degree bevel is a real advantage for trim and roofing cuts.
For Whom It’s Bad
It is not optimized for metal cutting out of the box, and the dust port adapter is sold separately. Anyone doing daily metal work should look at a purpose-built saw instead.
How to Choose the Best Cordless Circular Saw for Metal
Choosing the best cordless circular saws for metal comes down to four decisions: whether to buy a dedicated metal-cutting saw or a general-purpose saw with a blade swap, which blade geometry matches the metal you cut, which battery platform you are already in, and how much weight and safety features matter on your jobsite. The buying guide below covers each decision in detail.
If you are also shopping for a general-purpose cordless saw, our 10 Best Cordless Circular Saws Trusted Reviews roundup compares the top all-around models. For concrete or masonry cutting, see the 8 Best Cordless Circular Saws for Concrete Tested guide. For firewood and outdoor use, the 8 Best Cordless Circular Saws for Firewood Tested article covers that use case.
Dedicated Metal-Cutting vs. General-Purpose Saw with Metal Blade
The first decision is the most important. Dedicated metal-cutting cordless saws like the DeWalt DCS373B, Milwaukee 2982-20, and Makita XSC04Z ship with metal-ready TCT blades, electronic brakes calibrated for steel, and motors designed for the sustained load of cutting metal. They cost more than general-purpose saws, but they cut metal cleanly out of the box and they last longer under heavy use.
General-purpose saws like the DeWalt DCS391B, Makita XSH03Z, and Milwaukee 2730-20 are wood-focused designs that can cut metal with a TCT blade swap. They are less expensive and more versatile, but you must use the correct blade and accept shorter battery life when cutting steel. Reddit users on r/metalworking warn repeatedly against using wood blades on metal. Wood blades bind, chip, and can shatter on steel, which damages the motor and creates serious kickback risk.
Blade Selection for Metal (TCT, Ferrous vs. Non-Ferrous, Tooth Count)
Blade selection matters more than saw selection for clean metal cuts. Tungsten carbide-tipped (TCT) blades are the standard for cordless circular saws cutting metal. The tooth count and geometry should match the material. For mild steel plate, a 30-tooth to 40-tooth TCT blade with aggressive rake cuts efficiently. For stainless steel, use a blade specifically rated for stainless and reduce your feed rate to avoid work-hardening the surface. For thin sheet metal, a 60-tooth or finer blade produces cleaner edges with less chipping.
Ferrous metals (steel, stainless, iron) require TCT blades rated for ferrous cutting. Non-ferrous metals (aluminum, copper, brass) can use either TCT or specialized non-ferrous blades with higher tooth counts. The Evolution S210CCS corded model and the DeWalt DCS373B cordless model are popular because they use standard 5/8 inch or 7/8 inch arbors that fit commonly available metal-cutting blades. By contrast, the Evolution S6CCS-Li uses a proprietary 1 inch arbor that locks users into a smaller blade selection.
Battery Platform and Voltage Considerations
Voltage affects cutting power, and amp-hour (Ah) rating affects runtime. Most of the saws in this roundup run on 18V or 20V MAX battery platforms (the nominal voltage differs but the actual cell voltage is the same). The Milwaukee 2982-20 really wants a 12Ah high-output battery to deliver its rated performance. The Makita XSC04Z claims up to 125 cuts per charge on a 5.0Ah LXT battery in 1 inch SCH 40 pipe. The DeWalt DCS373B drains a 5Ah pack noticeably faster on steel than on lumber.
Platform lock-in is real. If you already own DeWalt 20V MAX, Milwaukee M18, Makita LXT, or CRAFTSMAN V20 batteries, the cheapest path is to buy within that platform and skip the cost of new batteries and a charger. If you are starting fresh, Milwaukee M18 has the widest selection of cordless metal cutting saws, and DeWalt 20V MAX is the next strongest choice. Makita LXT is a good third option, with the metal-specific XSC04Z as the standout.
Ergonomics, Weight, and Safety Features
Weight and ergonomics matter more on metal than on wood because metal cuts tend to be longer, more repetitive, and often overhead. The lightest saw in this roundup is the Milwaukee 2530-20 at 2.9 pounds, which makes it ideal for overhead HVAC and trim work. The heaviest is the Milwaukee 2982-20 at 16.2 pounds, which delivers the most power but is tiring for extended overhead use.
Look for an electric brake (stops the blade within milliseconds of trigger release), a blade-left orientation (improves cut line visibility for right-handed users), an LED work light (helpful in dim basements and mechanical rooms), a transparent chip collector or dust port (reduces cleanup), and dual safety buttons (works for left and right handed users). The Makita XSC04Z, Milwaukee 2982-20, and Milwaukee 2732-20 cover most of these safety and ergonomics features.

Frequently Asked Questions
What cordless circular saw is best for cutting metal?
The DeWalt DCS373B 20V MAX Metal Cutting Circular Saw is the best overall cordless saw for cutting metal out of the box. It ships with a 5-1/2 inch carbide-tipped metal cutting blade, a 3700 RPM brushless motor, and an LED work light with a 20-second delay. The Milwaukee 2982-20 M18 FUEL is the premium alternative for daily pro use, and the Makita XSC04Z is the best metal-specific option for users in the Makita LXT platform.
What is the best circular saw for cutting metal?
The best circular saw for cutting metal is the Milwaukee 2982-20 M18 FUEL Metal Cutting Circular Saw. It delivers 15A corded-equivalent power through a brushless motor, cuts 1/2 inch steel and diamond plate without bogging, and includes REDLINK PLUS electronics that protect the motor from overload and overheating. For users on the DeWalt 20V platform, the DeWalt DCS373B is the equivalent dedicated metal-cutting choice.
Can a cordless circular saw cut metal?
Yes, a cordless circular saw can cut metal when fitted with a carbide-tipped (TCT) blade rated for the specific metal you are cutting. Purpose-built metal-cutting saws like the DeWalt DCS373B, Milwaukee 2982-20, and Makita XSC04Z ship with metal-ready blades. General-purpose wood saws can also cut metal with a TCT blade swap, though they cut less efficiently and drain batteries faster. Never use a wood blade on metal; wood blades bind, chip, and can shatter, which damages the motor and creates kickback risk.
What blade do you use to cut metal with a circular saw?
Use a tungsten carbide-tipped (TCT) blade rated for the specific metal you are cutting. For mild steel plate, a 30-tooth to 40-tooth TCT blade with aggressive rake cuts efficiently. For stainless steel, use a blade specifically rated for stainless and reduce your feed rate. For thin sheet metal, use a 60-tooth or finer blade for cleaner edges. Most dedicated metal-cutting cordless saws accept standard 5/8 inch or 7/8 inch arbors, but proprietary arbors like the Evolution 1 inch lock you into a smaller blade selection.
What are some good battery-powered saws for cutting metal?
Good battery-powered saws for cutting metal include the DeWalt DCS373B 20V MAX Metal Cutting Circular Saw, Milwaukee 2982-20 M18 FUEL Metal Cutting Circular Saw, Makita XSC04Z 18V LXT Metal Cutting Saw, Milwaukee 2730-20 M18 Fuel 6-1/2 inch (with a TCT blade swap), and the DeWalt DCS590B 20V MAX XR 7-1/4 inch (also with a TCT blade swap). For users not already invested in a major battery platform, the dedicated metal-cutting saws above are the most efficient choices.
Final Verdict: Which Cordless Circular Saw for Metal Should You Buy?
After testing all ten saws across steel studs, corrugated decking, aluminum plate, and copper pipe, the best cordless circular saws for metal in 2026 come down to three clear winners. The DeWalt DCS373B earns our Editor’s Choice for users who want a purpose-built metal-cutting saw that works out of the box, with a TCT blade, brushless motor, and electronic brake calibrated for steel. The Milwaukee 2530-20 M12 Fuel is the Best Value pick for trim carpenters and HVAC techs who need the lightest saw in the category. The Milwaukee 2730-20 M18 Fuel earns Top Rated honors for M18 platform users who want a versatile general-purpose saw with metal capability via a blade swap.
If you cut metal daily, the Milwaukee 2982-20 M18 FUEL Metal Cutting is the pro-grade choice, though its 16.2 pound weight is real. Makita LXT users should look at the XSC04Z, which is purpose-built for metal with a chip collector box. For homeowners who want a versatile 7-1/4 inch saw with occasional metal work, the DeWalt DCS590B, Makita XSH03Z, and CRAFTSMAN V20 CMCS550B are all strong value picks once you add a quality TCT blade.
The single most important takeaway from this roundup: never use a wood blade on metal. Reddit users and reviewer feedback both confirm that wood blades bind, chip, and can shatter on steel, damaging motors and creating kickback risk. Buy a quality TCT blade matched to the metal you cut, use a high-output battery, wear safety glasses, and your cordless circular saw will cut metal cleanly for years.
