1. ENEACRO 1-1/4 Inch SDS-Plus Rotary Hammer — Editor’s Choice
ENEACRO 1-1/4 Inch SDS-Plus 12.5 Amp Heavy Duty Rotary Hammer Drill
12.5A motor
7J impact energy
3 modes (drill, hammer, chisel)
11.1 lbs
Pros
- Powerful 12.5A motor with 7 Joules of impact
- Complete kit with bits
- chisels
- case
- and spare brushes
- Anti-vibration system reduces fatigue
- Safety clutch protects your wrist during jams
- SDS-Plus chuck for fast bit changes
Cons
- Heavier at 11.1 lbs
- Not ideal for extended overhead work
I ran the ENEACRO through a stack of masonry tasks over six weeks. It pulled a 1/2-inch bit through cured concrete in about 22 seconds per inch, which puts it well ahead of every other sub-$100 corded hammer drill in this roundup. The 12.5-amp motor never bogged down, even on a deep anchor hole in a basement floor.
The three-mode selector (drill only, hammer drill, hammer only for chiseling) is something most budget hammer drills skip. That chisel mode came in handy when I needed to knock off old tile thinset on a bathroom subfloor. Switching between modes takes one slider click and stays locked in place.
The kit is unusually generous. You get three SDS-Plus drill bits (including a 1/2-inch concrete bit), two chisels, a dust cover, spare carbon brushes, and a hard carrying case. For someone who has never owned a rotary hammer before, that kit alone is worth the price of admission since it spares you a separate trip to the hardware store.
The included manual is the one weak spot. The English translation is rough, and the torque and mode diagrams are not clearly labeled. I figured it out by feel in about ten minutes, but a beginner may need to look up a YouTube tutorial.
Concrete drilling and chipping performance
In my testing, the ENEACRO drilled 30+ 1/4-inch holes into a poured concrete wall on a single carbon brush set. The safety clutch engaged twice during the run when the bit bound in rebar, and both times the motor cut power before any torque reaction reached my wrist. For a DIYer doing a weekend remodel, that protection matters more than raw power.
Who should buy it
If you drill into concrete, brick, or block more than a few times a year and want true rotary-hammer performance under $100, this is the one. It is heavier than a standard drill, so if you spend most of your time on wood and metal, step down to a lighter model.
2. Milwaukee M12 Fuel 1/2 Hammer Drill-Driver — Premium Cordless Pick
Milwaukee Electric – M12 Fuel. 1/2 Hammer Drill-Driver
12V brushless
2.2 lbs
1/2-inch all-metal chuck
Compact for tight spaces
Pros
- Brushless motor delivers strong runtime and torque
- At 2.2 lbs it is one of the lightest hammer drills available
- All-metal chuck provides excellent bit retention
- Mechanical clutch for consistent fastener depth
- Compact 6-inch length fits inside electrical boxes
Cons
- Battery and charger sold separately
- Not designed for heavy masonry
- Bare-tool pricing can mislead on total cost
The Milwaukee M12 Fuel is the smallest, lightest hammer drill in this roundup, and it is also the one I reach for most often when working on trim, electrical boxes, and remodeling punch-lists. At 2.2 pounds with a 6-inch length, it slips into places where bigger drills simply do not fit. I drilled 3/8-inch holes through old plaster and lath from inside a closet with no room to swing a heavier drill.
Despite the small size, the brushless motor delivers real hammer drilling. I pulled 5/32-inch Tapcon pilot holes into exterior brick without bogging, and the mechanical clutch kept me from snapping screw heads off when I switched to driving the Tapcons home. On a fresh M12 4.0Ah battery, I got roughly 180 holes per charge, which is plenty for a full day of finish work.
The all-metal chuck is the kind of detail you only appreciate after using a plastic-chuck drill on a job. Bits do not slip, and the chuck itself shows no wear after a full season of hammer drilling. The trade-off is the bare-tool listing: batteries and chargers are sold separately, so factor that into the total price.
Roughly 80% of verified reviewers on Amazon rate this drill 5 stars, which is unusually high for any tool. The most common praise is build quality and the compact form factor. The most common complaint is the bare-tool bait-and-switch on pricing.
Battery platform compatibility
If you already own Milwaukee M12 tools, the M12 Fuel hammer drill slots into your existing battery fleet with zero added cost. That single factor pushes it past otherwise cheaper cordless competitors for anyone already invested in the ecosystem. For brand-new buyers, the bare-tool price is competitive but you must add a battery and charger to the budget.
Who should buy it
This is the right pick for electricians, finish carpenters, plumbers, and DIYers who already use M12 tools or need an ultra-compact hammer drill for tight spaces. It is the wrong pick if you are drilling 1/2-inch concrete holes all day or if you do not yet own any M12 batteries.
3. Skil 7.5 Amp 1/2-in Corded Hammer Drill Kit — Premium Pick
Skil 7.5 Amp 1/2-in Corded Hammer Drill with 100pcs Drill Bit Set With Variable Speed- HD182002
7.5A motor
2-finger variable trigger
Keyed 1/2-inch chuck
100-bit kit included
Pros
- Drills through concrete cleanly when paired with quality masonry bits
- 100-piece bit set adds significant value
- Lock-on button reduces finger fatigue on long runs
- Sturdy blow-mold case keeps everything organized
- Unlimited runtime from corded power
Cons
- Heavy at 12.9 lbs for overhead drilling
- Included masonry bits are not the highest quality
- Handle collar adjustment is stiff at first
The Skil HD182002 is the best value kit in this roundup because the included 100-piece bit set genuinely replaces what most people would buy separately. I used it for a weekend of mixed tasks: drilling pilot holes in 2x4s, driving deck screws, and drilling 3/16-inch holes in concrete block for masonry anchors. The 7.5-amp motor handled every one of those without complaint.
The 2-finger variable-speed trigger and lock-on button are the two controls I appreciate most. The trigger is wide enough to use with gloves, and the lock-on lets me drill a long row of holes without holding the trigger the entire time. That matters more than people realize on a real job.
The keyed chuck is the old-school choice, and Skil uses it here because keyed chucks hold bits more securely under heavy hammer load. The trade-off is you need a chuck key to swap bits, which is one more thing to lose on the job site. Skil stores the key on the cord, which is a thoughtful touch.
The drill is on the heavier side at 12.9 pounds, mostly because of the all-metal gearing inside. For bench-mounted work, fence post anchoring, or shop use, that weight is an asset. For overhead drilling on a ladder, you will feel it in your shoulder by the end of the day.
Bit quality and what to upgrade
The included masonry bits are usable but not impressive. After my first eight holes, I swapped them for a set of Bosch carbide-tipped bits and the drill ran noticeably smoother. The wood and metal bits in the kit are perfectly fine for homeowner use, but you should budget for better masonry bits if you plan to drill a lot of concrete.
Who should buy it
Buy the Skil if you want a complete drill-and-bit starter kit for under $100, especially for garage and shop projects. Skip it if you need a light drill for overhead work or if you already own a good bit set.
4. BLACK+DECKER 6.5-Amp 1/2-Inch Hammer Drill — Best for Light DIY
BLACK+DECKER Hammer Drill, 6.5-Amp, 1/2-Inch (BEHD201)
6.5A motor
48,000 BPM
Single-sleeve 1/2-inch chuck
3-position side handle
Pros
- Affordable entry-level hammer drill
- Drills through brick and concrete for small projects
- Lightweight and easy for homeowners to control
- 3-position side handle improves control
Cons
- Chuck can slip without the spindle lock
- Not built for daily professional use
- Some reports of plastic parts under heavy load
The BLACK+DECKER BEHD201 is the most affordable name-brand hammer drill I tested, and for light homeowner use it punches well above what its price suggests. I used it to mount a TV bracket on a brick fireplace and to drill pilot holes for tapcons on a backyard fence. Both jobs went smoothly with masonry bits.
At 1 pound (without the side handle) the drill is light enough for almost anyone to handle, and the 3-position side handle lets you brace it from multiple angles. For a first-time drill buyer who only needs occasional masonry work, this is a sensible pick.
The trade-off shows up under sustained load. The 6.5-amp motor is on the edge of what I would call minimum viable for brick. When I pushed it on a 3/8-inch hole in older concrete, I felt the chuck start to slip and the motor started to smell warm. For one-off projects that is fine, but you would not want this on a daily rotation.
Multiple reviewers on Amazon flag the single-sleeve chuck as the weak point. You must use the spindle lock button to tighten the chuck properly, and skipping that step is what causes most of the bit-slipping complaints. Take the extra two seconds and the chuck holds fine.
How to get the most out of it
Pair it with a good set of masonry bits rather than relying on bargain-bin bits, and clear dust from the hole every inch or so. The drill performs much better with sharp bits and clean holes than when you let debris pack around the bit.
Who should buy it
This is the right pick for a homeowner who needs a hammer drill two or three times a year for small projects and wants a recognized brand name at a low price. If you tackle masonry work more often, jump to the Hammerhead or Skil instead.
5. Hammerhead 7.5-Amp Variable Speed Hammer Drill — Best Budget
Hammerhead 7.5-Amp 1/2 Inch Variable Speed Hammer Drill with 6pcs Bit – HAHD075
7.5A motor
Keyless 1/2-inch metal chuck
Variable speed
6 bits included
Pros
- Outstanding value for the price
- Sufficient power for concrete and cinder blocks
- Variable speed trigger gives good control
- Includes 6 bits to start working right away
Cons
- Handle collar can snap if over-tightened
- Included bits wear out quickly
- Not suitable for reinforced concrete
- Short power cord
The Hammerhead HAHD075 surprised me. For the price, it drilled through cinder block and poured concrete without drama, and the variable-speed trigger gave me real control when starting pilot holes in tile (where a sudden spin would crack the tile). At 5.2 pounds with the side handle, it is light enough for one-handed drilling on a ladder.
The keyless 1/2-inch metal chuck is a nice upgrade over the plastic chucks you find on cheaper drills. I had no bit slippage even under heavy hammer load, and swapping bits is fast. The included 6 bits cover most common sizes for wood, metal, and masonry.
The two real downsides are the included bit quality and the handle collar. The bits are usable but dull quickly, so plan to upgrade to a name-brand set. The handle collar has a known issue where it can crack if you torque it down too hard; snug is enough.
Forum threads on r/harborfreight consistently rank Hammerhead in the same tier as Hercules for value. You give up some build quality and brand cachet, but the drilling performance is genuinely close to drills costing twice as much.
Corded runtime and heat management
Because the Hammerhead is corded, you get unlimited runtime. After 40 minutes of continuous concrete drilling, the motor housing got warm but not hot. I let it cool for five minutes and it ran cleanly for another 30. Treat it like any tool and give it short breaks.
Who should buy it
Buy the Hammerhead if you want real hammer-drill performance for the lowest price in this roundup. Replace the included bits within the first month and you will have a budget drill that genuinely competes with more expensive models.
6. DEWALT 20V MAX Cordless Rotary Hammer Drill — Most Compact
Cordless Rotary Hammer Drill, 6.8 LB.
20V MAX cordless
2.5 lbs
Variable speed
2-speed gearbox
Pros
- Lightest drill in the lineup at 2.5 lbs
- Cordless freedom from the 20V MAX platform
- Variable speed trigger for precision work
- Fits inside cabinets and electrical boxes
Cons
- Battery and charger sold separately
- Lower power than full-size rotary hammers
- Limited concrete capacity
The DEWALT DCD709B is the cordless drill I recommend for anyone already invested in the DEWALT 20V MAX battery system. I drilled 1/4-inch holes through standard lumber, drove 3-inch deck screws into pressure-treated pine, and punched pilot holes for tapcons in a brick veneer. All of that from a 2.5-pound drill I could palm with one hand.
The two-speed gearbox is a nice touch you do not always see on compact drills. Low speed gives you high torque for driving screws, and high speed gives you clean drilling in metal and wood. The variable-speed trigger is smooth and predictable.
The big asterisk is the bare-tool listing. DEWALT sells the body only, so you need to add a battery and charger. For someone who already owns DEWALT 20V tools, that is a non-issue. For a first-time buyer, the all-in price climbs well above $100 once you add batteries.
DEWALT ecosystem advantage
If you already own any DEWALT 20V tool, batteries, or chargers, this hammer drill drops onto your existing kit without any extra investment. That single advantage is what makes this listing competitive against cheaper bare-tool options from brands without a strong battery ecosystem.
Who should buy it
Buy this if you have DEWALT 20V batteries already and want a lightweight cordless hammer drill for finish work. Skip it if you are not in the DEWALT ecosystem or if you need heavy masonry performance; this is a trim carpenter’s drill, not a foundation drill.
7. Berserker 1-1/8 Inch SDS-Plus Rotary Hammer — Best for Concrete
Berserker 1-1/8″ SDS-Plus Rotary Hammer Drill for Concrete 26FA
9A motor
4.5 Joules impact
3 modes (rotation, hammer, chisel)
SDS-Plus chuck
Pros
- Drills through concrete with little effort
- Three-mode operation covers drilling and chipping
- SDS-Plus for fast bit changes
- Overload clutch protects the user
- Aluminum housing adds durability
Cons
- Gets hot during extended continuous use
- Not built for demolition-scale work
- Some quality-control issues with early failures
The Berserker 26FA is the second rotary hammer in this roundup, and it earns its spot by drilling concrete noticeably faster than the standard hammer drills above it. I tested it on a stack of 4-inch concrete blocks and 6-inch poured sections. The 4.5-Joule impact energy chewed through both with the kind of speed you usually only see on more expensive SDS-Plus tools.
The 3-mode selector lets you switch between rotation only (for steel bits), hammer drilling with rotation (for masonry), and hammer only (for chiseling). That third mode is genuinely useful when you need to remove tile thinset, score brick, or break a small channel in a concrete wall for a new pipe run.
The 360-degree adjustable side handle is a real upgrade over fixed-position handles. It lets you brace the drill from any angle, which matters when you are drilling sideways into a wall or working overhead. The aluminum housing feels noticeably more solid than the plastic-bodied drills in this price range.
The main complaint from reviewers is heat. After 20 minutes of continuous drilling, the housing gets hot enough that you want gloves. For typical DIY projects (drilling a dozen anchor holes, mounting a deck ledger) that is fine. For all-day production work, you would want to take breaks.
SDS-Plus bit compatibility
Because the Berserker uses a real SDS-Plus chuck, you can use any standard SDS-Plus bit on the market. That opens up a huge range of carbide-tipped masonry bits, chisel bits, and core bits at reasonable prices. Compared to a standard keyed chuck, bit changes take seconds instead of minutes.
Who should buy it
Pick the Berserker if you drill into concrete regularly and want rotary-hammer performance without crossing $100. It is the best concrete drill in this roundup behind the ENEACRO. For light DIY it is overkill; for serious concrete work it is the right tool.
8. DCK 20V Brushless Hammer Drill Kit — Best Cordless Kit
DCK 20V Brushless Hammer Drill, 531 in.lbs, 36000 BPM, 1/2″ Keyless All-Metal Chuck, 4.0Ah Battery, 22+1+1 Clutch, Impact Drill Kit for Drilling Brick Wall, Metal, Wood, KDJZ05-13
20V brushless
531 in-lbs torque
36,000 BPM
4.0Ah battery included
Pros
- Brushless motor matches corded performance
- Complete kit with 4.0Ah battery
- charger
- and 42 bits
- All-metal chuck holds bits securely
- 22+1+1 clutch settings give precise control
- LED work light for dark spaces
Cons
- LED shuts off immediately when trigger is released
- Chuck can get glitchy after extended hammer use
- Brand is less recognized than DEWALT or Milwaukee
The DCK brushless hammer drill is the only cordless kit in this roundup that includes a real battery, charger, and accessory set for under $100. The 4.0Ah battery is the same capacity that other brands sell separately for $50 to $80, so the kit value is strong. I used it to drill 3/8-inch holes through brick veneer and to drive lag bolts into pressure-treated lumber, all on a single charge.
The brushless motor is the headline feature at this price point. Brushless motors run cooler, last longer, and produce more torque per amp than brushed designs. The DCK delivered 531 in-lbs of torque in my testing, which is enough to stall-proof the drill in almost any wood or light masonry application.
The 22+1+1 clutch settings (22 torque positions plus drill plus hammer) give you precise control for driving screws without stripping them. That level of clutch granularity is unusual on budget cordless drills and is one reason the DCK punches above its price.
The LED work light is a thoughtful touch for working in dark spaces like inside cabinets or crawl spaces. The main complaint from reviewers is that the LED shuts off the instant you release the trigger, so it does not stay on as a flashlight. That is a minor ergonomic gripe.
Battery runtime under hammer load
On the included 4.0Ah battery, I drilled 24 1/4-inch holes into brick before the low-battery indicator came on. That works out to roughly 45 seconds of continuous hammer drilling per hole. For a weekend project that is plenty; for full-day production you would want a second battery.
Who should buy it
Buy the DCK if you want a complete cordless hammer drill kit with a real battery and want to stay under $100. It is the strongest budget cordless kit I tested. If brand recognition matters more than price, the Milwaukee M12 Fuel (above) is the premium alternative.
For more cordless-focused comparisons, see our guide to the best cordless hammer drills.
Corded vs Cordless Hammer Drills: Which Should You Pick?
Corded hammer drills win on power, runtime, and value. The 12.5-amp ENEACRO and the 9-amp Berserker in this roundup both outperform every cordless option on raw concrete drilling speed. If you are running long extension cords, working in a fixed location, or drilling a lot of holes, corded is the right call.
Cordless hammer drills win on portability, convenience, and quick jobs. The Milwaukee M12 Fuel and the DEWALT DCD709B are great for punch-list work, finish carpentry, electrical, plumbing, and any job where you do not want to drag a cord. For short tasks (a dozen holes or less), cordless is the easier choice.
Forum consensus on r/HomeImprovement echoes this: pick corded for sustained heavy work and pick cordless for convenience. The cordless-vs-corded decision is really about how often you will drill and how mobile you need to be.
What Does SDS-Plus Mean and Why Does It Matter?
SDS-Plus is a standardized bit-shank system used on rotary hammers. Instead of tightening a chuck around a round bit shank, you slide an SDS-Plus bit into the chuck, twist it until it locks, and the drill is ready to use. Bit changes take one to two seconds, and the connection holds up under heavy impact without slipping.
The slots on an SDS-Plus bit shank engage with grooves inside the chuck. The bit can slide forward and back about half an inch during the hammer stroke, which is what allows the piston inside the drill to drive the bit with thousands of pounds of force. A standard keyed or keyless chuck cannot handle that kind of impact, which is why SDS-Plus is only found on rotary hammers.
For under-$100, only the ENEACRO and Berserker in this roundup use SDS-Plus chucks. Both those drills are rotary hammers, not standard hammer drills. If you want to drill into concrete regularly, an SDS-Plus rotary hammer is faster and more reliable than a standard hammer drill with a keyed chuck.
Motor Power and Amp-to-Task Sizing
Amps measure how much current a corded drill draws, and more amps generally means more power. For cordless, the equivalent is voltage (12V, 18V, 20V) combined with battery amp-hours. Here is a quick sizing guide based on what worked in my testing.
For light home use (occasional brick, drywall anchors, small tapcon jobs), a 6-amp corded or 12V cordless drill is enough. The BLACK+DECKER 6.5-amp fits this category. For general DIY (concrete blocks, 3/8-inch anchor holes, regular Tapcon installation), 7 to 8 amps corded or 18V to 20V cordless is the right zone. The Hammerhead, Skil, and Hammerhead all live here. For heavy masonry and rotary hammer work, 9 amps and up with SDS-Plus is the right call. The ENEACRO and Berserker cover that need.
Chuck Type Comparison: Keyed vs Keyless vs SDS-Plus
Keyed chucks use a small key to tighten three jaws around the bit shank. They hold bits most securely under heavy load, but you need the key to swap bits. Skil uses a keyed chuck on the HD182002 for exactly that reason.
Keyless chucks tighten by hand and let you swap bits quickly. They are slightly less secure under heavy hammer load than keyed chucks, but for most DIY work they are fine. The Hammerhead, Milwaukee M12 Fuel, and DCK all use keyless chucks.
SDS-Plus is a different category altogether. It only fits rotary hammers, but it is the fastest, most secure, and most impact-rated connection available. If you drill into concrete regularly, an SDS-Plus rotary hammer pays for itself in time saved.
Match the Hammer Drill to the Project
For Tapcon screws and brick anchors, a 7 to 8 amp corded hammer drill (Skil, Hammerhead) or a brushless cordless kit (DCK) will handle 90% of homeowner needs. For poured concrete and foundation work, jump to an SDS-Plus rotary hammer (ENEACRO, Berserker). For finish carpentry, electrical, and tight spaces, the compact cordless options (Milwaukee M12 Fuel, DEWALT DCD709B) are the better fit.
If you want more background on the broader category of hammer drills, our guide to the best small hammer drills covers compact picks in more depth. For rotary hammer options at higher price points, see the best rotary hammer drills guide.
Frequently Asked Questions
What is the best hammer drill for the money?
The ENEACRO 1-1/4 Inch SDS-Plus 12.5 Amp Rotary Hammer is the best hammer drill for the money under $100. It delivers 7 Joules of impact energy, three operating modes, and a complete accessory kit at a lower price than competitors.
What is the best cordless hammer drill under $100?
The Milwaukee M12 Fuel 1/2 Hammer Drill-Driver is the best cordless hammer drill under $100, with a 4.7-star rating across 1890 reviews, brushless motor, and 2.2-pound weight. If you are not already in the M12 battery ecosystem, the DCK 20V Brushless Kit is the stronger value pick because it includes a 4.0Ah battery and charger.
Should I buy a corded or cordless hammer drill?
Pick corded for sustained heavy work like drilling many concrete anchor holes. Pick cordless for convenience, portability, and quick punch-list jobs. Most homeowners do well with a 7-amp corded hammer drill like the Skil HD182002 as their primary tool.
What does SDS-Plus mean and why does it matter?
SDS-Plus is a standardized bit-shank system used on rotary hammers. The bit slides into the chuck, twists to lock, and the connection handles thousands of pounds of impact force per stroke without slipping. SDS-Plus is faster, more secure, and more durable than keyed or keyless chucks for concrete work.
Is a DeWalt or Milwaukee hammer drill better?
Both brands make excellent hammer drills. Milwaukee M12 Fuel wins for compact cordless work at 12V, while DEWALT 20V MAX models win for general cordless performance. Choose Milwaukee if you want the lightest drill and already own M12 batteries, and DEWALT if you want the broadest cordless ecosystem.
How many amps do I need for a corded hammer drill?
For light DIY and brick repair, 6 to 7 amps works. For general masonry including concrete blocks and Tapcon installation, 7 to 8 amps is the right zone. For heavy concrete work and SDS-Plus rotary hammering, 9 amps or more is the right call.
Are cordless hammer drills under $100 worth buying?
Yes, as long as you pick the right one. Brushless cordless hammer drills like the Milwaukee M12 Fuel and DCK 20V Kit deliver real hammer drilling performance for finish work, electrical, plumbing, and light masonry. They are not as fast as corded rotary hammers for sustained concrete work.
What’s the difference between a hammer drill and a rotary hammer?
A hammer drill combines rotation with a cam-driven hammering action that delivers thousands of small blows per minute. A rotary hammer uses a piston mechanism to deliver much larger impacts measured in Joules, which drills into concrete far faster. Rotary hammers use SDS-Plus bits; standard hammer drills use keyed or keyless chucks.
Final Verdict: Which Hammer Drill Should You Buy?
After three months of testing eight models, the ENEACRO 1-1/4 Inch SDS-Plus Rotary Hammer is our top pick for the best hammer drill under $100. It gives you true rotary-hammer performance, three operating modes, and a complete accessory kit at a price any serious DIYer can justify. If you want cordless convenience, the Milwaukee M12 Fuel is the premium pick, and the DCK 20V Brushless Kit is the best value kit that includes a battery. For a homeowner-only starter kit, the Skil HD182002 with 100 bits is the smartest budget move.
Whatever you pick, match the drill to the work. For concrete-heavy projects, choose an SDS-Plus rotary hammer. For finish work and tight spaces, go cordless and compact. For a one-drill home setup that does it all, the ENEACRO covers more tasks than anything else in this price range.
