The 1-3/4 in SDS MAX® combination hammer is a midweight, high performance hammer that is powered by durable German engineered mechanisms. It delivers 10.5 J of impact energy for fast drilling and chipping, even in the hardest concrete. Constant speed electronics allow the tool to maintain speed under load, while the patented E-Clutch® system helps protect the user in bind up situations by stopping the rotation of the bit. The midweight design makes it ideally suited for high performance, horizontal serial drilling for #5 to #8 rebar, dry coring up to 4 in, chipping in any upper to lower wall and bushing applications. The SHOCKS Active Vibration Control® system 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 Tool Connect™ app.
