The DCD740B has a front to back length of 4.0 inches, which lets it fit between studs spaced 16 inches apart with room for a battery. A dual speed gearbox covers 0 to 650 rpm for large bits and 0 to 2,000 rpm for small ones. A multi-grip trigger lets you hold the tool in several positions.
It is a bare tool, so you need 20V MAX batteries. Compared with the Ryobi HP it has a wider speed range, and compared with the Makita XAD02Z it offers far more speed headroom. It is not a Hole Hawg, so one inch bits in dense timber are better done by the Milwaukee.
Expect a compact tool that is easy to store. Keep the chuck free of dust and avoid dropping the gear head. Bits with a hex shank work well in the tight chuck.
