A cordless hammer drill has to do two things. It must hit masonry hard enough to drill brick and block, and it must stay light enough for overhead work and long sessions. Look at blows per minute, no-load speed, weight, length and chuck type. Also check whether the tool runs on a battery at all, because several listings here are corded. We put 10 products on one spec sheet so you can compare them directly. Our ranking uses specs, and we flag the ones that miss the cordless brief.

We reviewed 19 hammer drills and kept only the 10 that pass every check below. Those are ranked by a Best Score built from spec fit for this job, warranty, sales rank.
These reviews are based on specifications and listing information. They cover the top five ranked products, and we flag the corded ones.
Leads our ranking, but it is corded
This is a corded tool, so it does not match the battery-powered need in this keyword. It leads our ranking on specs alone. The motor draws 7.5 A, and the maker lists 3000 RPM and 48000 BPM. Higher BPM means more impacts each minute, which helps when drilling into brick and block.
Weight is 5.18 lb and length is 11.75 in. That is heavier than the cordless DEWALT models here, which makes overhead work tiring sooner. It has a side handle and a depth rod, which help you hold the drill steady and stop at the right depth. A lock-on trigger and variable speed add control for longer jobs.
The listing says it cannot be used in reinforced concrete walls. That limits it to lighter masonry. It has a keyless 1/2 in metal chuck, so bit changes are quick. It suits garage and shop use better than ladder work. Pick it only if a cord is fine for your work.
VerdictA capable corded drill that tops our ranking, yet it misses the cordless brief.
The lightest drill here, and truly cordless
This is the cordless model that best fits the keyword. It ranks second in our list. It weighs 3.49 lb, the lowest weight among the nine products that list it. Light weight matters for overhead holes and long sessions, because your arm carries the tool the whole time. Length is 7.32 in, so it fits into tighter spots.
It is a 20V MAX XR brushless drill with a 1/2 in keyless chuck. The listing gives two speed settings, with no-load speed up to 2000 RPM. It also lists an LED work light and an anti-rotation system that shuts the tool down if it twists too much. The data gives no BPM figure, so its impact rate cannot be compared with the others.
The listing claims up to 175 holes per charge. It is sold as tool only, so you need to supply a battery and charger. For masonry work, check that the missing BPM figure suits your concrete needs. Weight and size are its clearest strengths.
VerdictThe best fit for the keyword on weight and cordless design, with one gap on impact data.
Cordless DEWALT with a real impact rate
This 20V MAX XR brushless drill lists 38250 BPM, which is the impact rate you want for brick and block. It ranks third on our list. It also lists 2250 RPM, higher than the other cordless DEWALT here at 2000 RPM. Of the two cordless DEWALT models, it is the one that publishes an impact rate.
Weight is 4 lb, light enough for overhead work, though heavier than the 3.49 lb DCD806B. The listed length of 4 in is the lowest on the page, but it looks short for a drill with a 1/2 in chuck, so check it before you buy. The chuck is a keyless ratcheting metal design with carbide inserts for bit grip.
The listing says the motor gives up to 75% more runtime than 18V NiCad brushed motors. That compares to old battery tech, not to rivals. It also has a three-mode LED light for dark spaces. Battery details are not in the data.
VerdictA cordless pick with a published impact rate that suits light masonry work.
Highest speed and BPM, but corded and renewed
This model leads the page on speed and impact. It lists 3100 RPM and 52700 BPM, both the highest among the models that list them. A high BPM figure means more hammer strikes each minute, which helps in brick and block. It is a corded drill, so it does not fit a battery-powered search.
Weight is 5.29 lb and length is 12.4 in. That is on the heavy side for overhead use, and longer than both cordless DEWALT models here. The chuck is keyed. The listing says this improves bit retention, but you need a key to change bits. A lock-on trigger and variable speed help on long jobs. The data lists no side handle or depth rod.
The title says Renewed, so it is not sold as new. The data lists a warranty of 3 years. Read the seller terms before you buy. Check what the seller includes in the box. It ranks fourth on our list.
VerdictThe strongest numbers on the page, but the wrong tool for a cordless search.
Highest motor current, but corded
The DW511 has the highest motor current in the lineup at 7.8 A, among the six models that list it. More amps means the motor can draw more power for tough masonry. It is corded, so it misses the battery-powered need in this keyword. It ranks fifth on our list.
Max speed is 3000 RPM, and the drill has a keyless chuck. That top speed matches the Hammerhead and Bosch models on this page. It also has a side handle and a depth rod. The listing says the handle turns 360° and the rod improves depth accuracy. The data lists no BPM figure, so impact rate cannot be compared.
Weight is where the data conflicts. The spec says 5.55 lb, while the listing text says 4.3 lbs. Going by the spec figure, it is heavier than the cordless DEWALT models. Length is 12.19 in, so it is long for overhead use. Check the real weight before you buy.
VerdictA strong-motored corded drill, but it does not answer the cordless brief.
Best among the reviewed tools
Several top-ranked products on this page are corded. If you want battery power, look for 20V-class names and check whether a battery and charger come in the box. Some listings say tool only. Ranking on specs alone does not account for cord versus cordless.
BPM counts how many times the hammer action strikes each minute. More strikes help in brick and block. Not every listing publishes it. Among the eight products that list BPM, the range runs from 25500 to 52700.
Overhead work and long sessions punish heavy tools. Listed weights run from 3.49 lb to 8.15 lb among the nine that list weight. Length runs from 4 in to 14.96 in. Treat very short lengths with care and confirm them on the maker page.
Keyless chucks change bits by hand. Keyed chucks need a key. A side handle and a depth rod help control and hole depth, but the data lists them only for some models. Check these before you buy.
The DEWALT DCD806B lists 3.49 lb, the lowest weight among the nine products that list weight. The DEWALT DCD996B lists 4 lb. Both are cordless 20V MAX XR brushless drills with 1/2 in keyless chucks.
Yes, for masonry. BPM is how many impacts the drill delivers each minute. The DEWALT DCD996B lists 38250 BPM. The DEWALT DCD806B does not list a figure, so check the maker's page if impact rate matters for your concrete work.
Not all. The Hammerhead HAHD075 lists itself as corded, and so does the CRAFTSMAN CMED741R. The DEWALT DW511 lists an amp rating, which points to a corded tool. The DEWALT DCD806B and DCD996B are the cordless picks in the top five.
The Hammerhead listing says it cannot be used in reinforced concrete walls. Other listings give no such rating, so do not assume they can. Check the maker's guidance for concrete and rebar before you drill.
