The Milwaukee M12 FUEL SURGE 1/4 in. Hex Hydraulic Driver is the industry's first 12-Volt hydraulic impact driver. Featuring the FLUID-DRIVE Hydraulic Powertrain, the hydraulic impact will allow users to experience operation up to 2X quieter with less vibration for smoother and faster driving speeds compared to standard impacts. The compact size of the tool and battery provides users with unmatched access in tight spaces & allows for easy transport on a tool belt and easy fitting into a job site tool bag. Performance is not sacrificed despite lower peak torque due to its Longer Sustained Torque that allows the tool to complete core users most common applications. The POWERSTATE Brushless Motor delivers up to 0 RPM-3,000 RPM with constant power output to drive screws faster. Built-in REDLINK PLUS intelligence is the most advanced electronic system on the market, preventing damage to the user's tool and battery caused by overloading or overheating. The cordless impact driver is compatible with all Milwaukee M12 REDLITHIUM Compact Batteries or Extended Capacity Batteries, delivering users with more work per charge and more work over the life of the pack than competitive batteries. The impact driver's 4-Mode DRIVE CONTROL provides users with greater control over output speed and power for greater versatility in a wide range of applications. Self-Tapping Screw Mode reduces walking when users are self-tapping screws as well as reduces overdriving, breaking and stripping out screws.
