The DEWALT DCH773Y2 is the industry"s most powerful cordless 2 in. SDS MAX combination rotary hammer. The 60V MAX* Cordless 2 in. SDS MAX Combination Hammer is a heavy weight, high-performance hammer that is powered by a brushless motor and a durable German-engineered mechanism. It delivers 19.4 Joules of impact energy for fast drilling and chipping, even in the hardest concrete. The constant speed electronics allow the tool to maintain speed under load. The heavy weight design makes it ideally suited for horizontal and downward drilling for #9 - #14 rebar dowel applications, dry coring up to 6 in., chipping in any lower wall and floor, ground rod driving, and bushing. This hammer is part of the PERFORM & PROTECT™ product line, integrated with the Anti-Rotation E-CLUTCH® System and the SHOCKS Active Vibration Control® System. E-CLUTCH® shuts down the tools in bind up situations. SHOCKS™ reduces vibration felt by the user at the handles, compared to rotary hammers without this feature. This tool comes Tag Ready™ so users and companies can attach the DEWALT Tag™ and track its location virtually anywhere via the DEWALT Tool Connect™ app.
