The Makita DTW700Z is a compact and powerful 1/2" impact wrench driven by an efficient brushless motor that delivers more run-time compared against traditional motors with carbon brushes and requires no maintenance.The DTW700Z has a maximum torque of 700Nm and an electronic 4 stage impact power selection for precision tightening/loosening of bolts and nuts up to M24. Features include an ergonomic soft-grip, LED job light and auto-stop system to prevent nuts from running off their threads and getting lost. A button allows the variable speed on the trigger to be bypassed and goes straight to "full-speed" mode which shortens the trigger travel reaching full speed quicker.The DTW700Z has a 1/2" square drive with C ring and is suitable for use with impact grade sockets only.Specifications: Blows per Minute (Max) - ipm: 0 - 2,700 ipmNo Load Speed (max/hard/med/soft): 0 - 2,200/ 1,900/ 1,200/ 500 rpmNut Busting Torque: 1,000 NmVoltage: 18 vDriving Shank: ½” Square Drive, C-ringBlows per
