Quick Answer: For serious concrete and masonry work, the Bosch GBH2-28L rotary hammer is our top pick. Its 2-pound rated impact energy plows through rebar-reinforced concrete while staying manageable for overhead work. If you only drill occasional anchor holes, a hammer drill will suffice, but for regular masonry work a rotary hammer is essential.
What to Look For
The most important spec for concrete drilling is impact energy, measured in foot-pounds. Rotary hammers use an electro-pneumatic mechanism that delivers far more force than standard hammer drills, which simply vibrate the bit rapidly. Look for SDS-Plus chuck systems for bits up to 1-1/8 inch, and SDS-Max for larger holes. Anti-vibration technology matters significantly since sustained concrete drilling causes fatigue and long-term joint issues. Variable speed control lets you start holes cleanly without wandering. Dust collection compatibility is increasingly important on jobsites due to OSHA silica dust regulations. Weight is a practical concern for overhead drilling into concrete ceilings or lintels.

How to Choose
If you drill into concrete weekly or more, invest in a rotary hammer. The Bosch GBH2-28L is unmatched for corded reliability on heavy commercial jobs. For contractors who need cordless flexibility, the Milwaukee 2912-20 pairs perfectly with an existing M18 battery fleet. The DeWalt DCH273B is the best choice for weight-conscious users doing overhead anchoring or those already on the 20V MAX platform. For homeowners who only need occasional concrete anchors, a quality hammer drill mode on a standard drill will handle light-duty work without the extra investment. If you need an all-purpose drill rather than a dedicated concrete tool, see our best cordless drills guide. Of the brands tested here, DeWalt's approach to cordless masonry work is worth understanding in context -- our DeWalt DCD999B review covers how its FLEXVOLT Advantage tech handles high-torque concrete work.

Which Drill Is Right for Your Concrete or Masonry Work?
Concrete drilling ranges from occasional anchor bolts to daily hole-drilling in commercial construction. The right tool depends entirely on hole diameter, volume, and material hardness.
Electrical, HVAC, and plumbing contractors -- You drill 3/4-inch to 1-inch holes through concrete walls and floors constantly, often in awkward positions. The Milwaukee 2912-20 M18 FUEL SDS-Plus is the professional-grade answer: 2.0 ft-lbs of impact energy, DRIVE CONTROL that prevents tool rotation on bit bind, and M18 battery compatibility with the rest of your platform. The POWERSTATE brushless motor maintains drilling speed under load without the slowdown that plagues standard rotary hammers in hard concrete.
General contractors and structural work -- Anchor bolts for Simpson Strong-Ties, ledger connections, and hold-down hardware require 1/2 to 3/4-inch holes with exact depth control. The DeWalt DCH273B's depth stop rod sets a precise drilling depth for consistent anchor embedment -- important when post-installed anchor performance depends on embedment depth matching the manufacturer spec. Its 20V MAX compatibility means one battery ecosystem covers your drill, circular saw, and rotary hammer.
Shop and garage users with power access -- The Bosch RH328VC corded model delivers 2.6 ft-lbs of impact energy -- 30% more than the cordless options -- and runs indefinitely without battery weight or management. For a fixed shop or basement workbench where you drill concrete anchors for shelving, machinery, and structural connections, the corded model's sustained power and lower purchase price make it the better value. It also includes a depth stop rod and a side handle for two-handed control on larger holes.
Homeowners drilling occasional anchors -- A 1/2-inch SDS-Plus rotary hammer handles all residential anchor work: concrete screws (Tapcon), wedge anchors, and sleeve anchors for up to 1/2-inch diameter holes. The SKIL RE4018 at its price point covers this usage well. If you find yourself drilling more than 10-15 holes per year in concrete, step up to the DeWalt DCH273B for the battery integration and better ergonomics on repeated work.
FAQ
What’s the difference between a hammer drill and a rotary hammer?
A hammer drill vibrates the bit rapidly while spinning. A rotary hammer uses an internal piston to deliver actual hammer blows, producing 3-5x more impact energy. For anything beyond small anchors in block, a rotary hammer is vastly more effective and less fatiguing.
Can I use a rotary hammer for regular drilling?
Yes, most rotary hammers have a rotation-only mode that works for standard drilling. However, the SDS-Plus chuck requires SDS bits, so you will need adapters or dedicated bits.
Do I need a dust collector for concrete drilling?
OSHA silica dust regulations require dust control on construction sites. Even for home use, a vacuum attachment dramatically reduces cleanup and protects your lungs. Most rotary hammers now have integrated dust collection ports.
What SDS bits should I buy for an SDS-Plus rotary hammer?
Bosch SDS-Plus bits are the benchmark for quality and consistency. For occasional use, Dewalt and Milwaukee SDS bits perform comparably. Avoid no-name bulk bit sets -- the carbide tip geometry and steel hardness are inconsistent, producing irregular holes and faster dulling in hard aggregate concrete. A quality 4-piece set (3/16, 1/4, 3/8, 1/2-inch) covers 90% of residential and light commercial anchor work. For anchor-critical structural applications, replace bits every 200-300 holes to ensure consistent hole diameter for proper anchor engagement.
How do I drill through reinforced concrete without hitting rebar?
Use a rebar scanner (available at equipment rental shops) to locate rebar before drilling. In post-tension slabs, this is critical -- cutting a post-tension cable is catastrophic and extremely dangerous. For ordinary reinforced concrete, if your bit contacts rebar mid-hole, stop immediately and relocate. Do not try to drill through rebar with an SDS bit. Mark the hole location 2-3 inches from the original position and re-drill. For structural anchors that must hit a specific location, consult the engineer of record before relocating.
Why does my rotary hammer keep stopping mid-hole?
Most stalls during concrete drilling are caused by aggregate contact (hitting a dense stone piece in the mix), a dull bit, or the tool's anti-bind clutch triggering. If you hit an aggregate pocket, apply steady forward pressure without forcing -- let the percussion action work the bit through. If the bit is dull (evident from poor penetration rate and excessive vibration), replace it. If the tool's clutch keeps triggering on normal drilling, you may be applying too much downward force. Let the hammer mechanism do the work; excessive pressure actually reduces drilling speed by overloading the bit.
