The FLEXVOLT 1-7/8 in. SDS MAX Combination Hammer, with its durable and hard hitting German engineered mechanism, delivers category leading 13.3 Joules of impact energy. Constant speed electronics allows the tool to maintain speed under load, even in the hardest concrete, while the patented E-Clutch ® system protects the user in bind up situations by stopping the rotation of the bit. This tool is ideally suited for horizontal and downward drilling for #5 - #9 rebar applications, core drilling up to 5 in. and chipping in any mid-to-lower wall and floor applications. Active Vibration Control® technology also reduces vibration felt by the user for less fatigue and greater productivity. 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.
