The Milwaukee M12 1/4-Inch Hex Impact Driver (Bare Tool) generates up to 1,000 inch-pounds of torque to quickly drive into hard surfaces. This driver is part of the versatile M12 tool series, and can run the same long-lasting REDLITHIUM batteries as the rest of your M12 collection. The cordless impact driver features variable speed of 0-2,500 RPM, so you can operate with a combination of speed and control, and conserve battery life for your more demanding tasks. An ergonomic handle reduces hand and wrist strain, and improves your grip to hold it more securely. The Milwaukee impact driver's keyless chuck allows you to make quick and easy bit changes so you can finish your task and get on to the next phase. An on-board gauge displays your battery's charge so you know when to get the replacement off the charger.
