The DEWALT 20V MAX SDS Rotary Hammer Drill is a versatile and powerful cordless tool designed for various applications such as drilling in concrete, installing seismic and safety attachments, and rail mounting. It features a robust brushless motor that offers efficient performance and long runtime. The drill operates at a maximum speed of 2800 RPM and provides 2.1 Joules of impact energy, making it highly effective in tough materials like concrete. With a lightweight design, it weighs only 6.4 pounds, which enhances user comfort during prolonged use, especially in overhead tasks or confined spaces.
The tool has a rotating dial that allows users to switch between drilling, hammer drilling, and chiseling modes easily, adding to its versatility. Additionally, the SHOCKS ACTIVE Vibration Control System reduces vibration, which minimizes user fatigue and offers a smoother operation compared to other rotary hammers without this feature. The maximum chuck size is 20 millimeters, which is suitable for a variety of bit sizes. However, the drill is sold as a bare tool, meaning it does not come with batteries, which must be purchased separately. This may be a drawback for some users who prefer an all-in-one package.
The drill is OSHA Table 1 compliant when paired with a compatible dust extractor, making it a suitable choice for professional environments that require strict dust control. The DEWALT 20V MAX SDS Rotary Hammer Drill stands out for its power, versatility, ergonomic design, and vibration control, although the need to purchase batteries separately may be a downside for some users.
The Milwaukee M18 FUEL 1-3/4 in. SDS M rotary hammer is a battery-powered drill designed for heavy-duty work, making it a strong choice if you need portability without being tied to a cord. It comes with two 12.0 Ah lithium-ion batteries, which promise good runtime and power for demanding tasks. The motor delivers 15 amps and up to 380 RPM, offering solid drilling speed and torque (8.1 foot-pounds) suitable for tough materials like concrete and metal up to 13 millimeters thick. The 1.75-inch chuck size is large enough for many professional-grade bits, fitting well with various drilling and chiseling jobs. However, it only has one speed setting, which might limit precision for more delicate work.
The drill weighs about 44 pounds, which is on the heavier side, so it may feel bulky during extended use despite its ergonomic design with glass-filled nylon material aimed at durability. The package includes two batteries and the tool itself, ready to go out of the box. It is best suited for professionals or serious DIYers who prioritize power and battery convenience over lightweight or variable speed features due to its weight and single-speed operation.

This makes it ideal for use in locations without easy access to power outlets. The motor delivers up to 324 watts, strong enough to handle tough materials like concrete. The tool’s SDS-Max chuck allows for quick bit changes and supports large drill bits common in professional jobs.
Weighing about 46 pounds, it is on the heavier side, which might make prolonged use tiring, but the metal construction promises durability. The product holds a perfect 5-star rating from available reviews, indicating high satisfaction among users who tried it. This rotary hammer suits professionals or serious DIYers needing a cordless, robust tool for demanding drilling tasks in construction or renovation.
