Cordless rotary hammer drills

A combination hammer covers four modes in one machine: hammer drilling, plain drilling, screwdriving, and chiselling. The SDS-Plus chuck swaps for a keyless chuck without tools, which is what makes the switch practical rather than theoretical. This is the one to reach for when a job mixes fixing into concrete with ordinary drilling and driving, and carrying three machines up a ladder isn't sensible. Chiselling brings it into light breaking work — removing tile, chasing, cutting back render — that a drill alone can't do.
