Makita-built brushless motor delivers 3,600 Max RPM and 1,590 in. 4-speed power selection (0-1,100/ 0-2,100/ 0-3,200/ 0-3,600 RPM & 0-1,100/ 0-2,600/ 0-3,600/ 0-3,800 IPM) provides precise fastening control for a wide range of applications. Additional one-touch 4-speed power selector button under the chuck for added convenience. Assist Mode (A-mode) feature helps eliminate “screw cam-out” and “cross threading” by driving at low speed until tightening begins. Two Tightening Modes (T-mode) for faster tightening of self-drilling screws in thick or thin gauge metal helps prevent damage to the screw or workpiece. Reverse rotation auto-stop mode stops rotation and impact when fastener is loosened adequately. Designed with dual ball bearing chuck to reduce bit wobble and run out.
