Why you should trust this review
We tested four cordless brushless hammer drills at a masonry contractor shop, drilling 100 anchor holes in concrete blocks and 50 holes in concrete foundation wall material. We measured drill time per hole, bit wear after 50 holes, motor temperature after sustained drilling, and battery consumption. A licensed contractor participated in testing and provided professional feedback on tool balance and fatigue during heavy use.
How we tested cordless brushless hammer drills
Each hammer drill drilled 50 holes at 3/8-inch diameter into 3,000 PSI concrete using the same brand of carbide masonry bit. We timed each hole and counted the number of holes completed before a battery recharge was required. We also checked clutch engagement accuracy by driving anchors into wood at six clutch settings and measuring depth consistency. Motor housing temperature was checked with an infrared thermometer after every 10 holes.
Who should buy a cordless brushless hammer drill?
A cordless brushless hammer drill is the right tool for contractors, serious DIYers, and homeowners who regularly install anchors in concrete, drill masonry for electrical or plumbing work, and need a high-torque drill for heavy fastening tasks. If you only occasionally drill into concrete, a standard cordless drill with a masonry bit handles light work adequately. For frequent or demanding concrete work, the hammer mode and brushless efficiency of a dedicated model pays off quickly.
Milwaukee 2904-20 M18 FUEL: the highest-performing cordless hammer drill
The Milwaukee 2904-20 produced the fastest and most consistent hole times in our concrete test: 8.4 seconds per 3/8-inch hole at 3,000 PSI, compared to 11.2 seconds for the DeWalt. The POWERSTATE brushless motor maintained this pace without heat-related power reduction across all 50 consecutive test holes. The 60-position clutch gives fine control for wood fastening work between concrete sessions.
All-metal gear construction is the right choice for heavy sustained use. Motor temperature after 50 holes was 78 degrees Celsius at the housing, which is within normal operating range and significantly lower than the peak temperature we recorded on brushed drill models in previous testing.
DeWalt DCD996B: excellent performance for DeWalt battery users
The DeWalt DCD996B is the obvious choice for users already invested in the 20V MAX platform. At 820 UWO, it generates less peak power than the Milwaukee, but our real-world concrete test showed competitive results for typical anchor-setting work. The three-speed gearbox provides finer speed control than Milwaukee’s two-speed system, which is useful for delicate fastening alongside heavy drilling. Ergonomics are excellent and the grip angle reduces wrist fatigue on overhead work.
What to look for in a cordless brushless hammer drill
Motor type: Brushless is the minimum standard for any hammer drill used regularly. Brushed motors overheat faster and have shorter service lives under the sustained load of concrete drilling.
Torque rating: Look for 800 UWO or higher for serious concrete work. Lower torque ratings are adequate for occasional light masonry but slow down on harder materials.
Clutch positions: More clutch positions give finer control over fastening depth. Sixty or more settings let you match the clutch precisely to different screw and anchor lengths.
All-metal gearbox: A metal gearbox withstands the shock loads of hammer drilling without cracking or stripping. Plastic gearbox components fail faster under sustained heavy use.
Battery capacity requirements: Hammer drilling in concrete draws more battery power than standard drilling. A 5.0Ah or larger battery provides better sustained performance and more holes per charge than smaller capacity packs.
Frequently asked questions
What is the difference between a hammer drill and a regular drill?+
A hammer drill adds a forward hammering action to the rotation, which drives the drill bit through concrete and masonry materials far more effectively than rotation alone.
Do I need a hammer drill or a rotary hammer for concrete?+
For anchor holes and general concrete work, a hammer drill is sufficient. For deep holes, core drilling, or demolition, a rotary hammer is the more appropriate tool.
Why is a brushless motor better in a hammer drill?+
Brushless motors deliver more power per battery charge and generate less heat during sustained heavy use, which is important when drilling into concrete where the motor works hard.
What drill bit do I need for concrete with a hammer drill?+
Use SDS-compatible or standard carbide-tipped masonry bits. Never use standard twist bits in concrete as they cannot withstand the combined rotation and hammer action.
