Engineered for professionals who demand hard-hitting power in an ultra-compact frame, the DEWALT DCH172B ATOMIC 20V MAX 5/8-inch SDS-Plus Rotary Hammer Drill delivers industrial-grade performance without the prohibitive weight of traditional rotary hammers. Driven by a high-efficiency brushless motor and a durable, German-engineered mechanism, this compact tool delivers an impressive 1.4 Joules of impact energy, making it an ideal choice for rod hanging, concrete forming, cable tray mounting, and structural bracket installations.

As part of DEWALT’s premium PERFORM & PROTECT™ product line, the tool features the SHOCKS Active Vibration Control® system. This technology dampens hand-arm vibration down to 8.8 m/s², significantly lessening user fatigue during extended all-day use. Designed for dynamic job sites, it offers a versatile two-mode selector switch to quickly shift between standard drilling and hammer-drilling applications. An integrated bright LED work light provides clear visibility in dark spaces, while the onboard tool tether point offers added safety when working at heights.
