- High-torque levels loosen or remove the most stubborn nuts and bolts with ease. Whether used for auto projects or construction work, this impact wrench achieves up to 1400 ft/lbs of breakaway torque and 1000 ft/lbs of fastening torque to power through tasks with effective results.
- The Intelligent Constant Torque System maintains consistent high-performance levels, so you never have to worry about losing torque when battery levels get low or during long periods of use.
- High-efficiency brushless motor runs 50% longer, delivers 25% more power, and has a 10X longer life than brushed motors.
- Do more, recharge less. The included Power Share PRO 5.0Ah battery is designed to stay cool, resist damage, and optimize power control to boost equipment runtime.
- Trigger features a patented non-contact control switch which stands tough against excess vibration and friction, unlike contact switches that wear down over time.
- Power through high-intensity jobs without wearing down the tool. With a special high-strength impact transmission, this impact wrench lasts much longer than competing products.
- With 4 Mode Control, switch between 3 Speed Settings + Auto Mode to get the perfect pace for different projects. Auto Mode maintains precise speed control and stops immediately once the bolt is loosened or fastened. In forward rotation, Auto Mode helps prevent overtightening. In reverse rotation, Auto Mode helps prevent bolts from falling off and getting lost when working overhead.
