Milwaukee's M12 FUEL SURGE™ 1/4” Hex Hydraulic Driver is the industry's first 12-volt hydraulic driver. Featuring our FLUID-DRIVE™ Hydraulic Powertrain, the hydraulic driver will let you 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 give you unmatched access in tight spaces and allows for easy transport on a tool belt and easy fitting into your job site tool bag. The POWERSTATE™ Brushless Motor delivers up to 0-3,200 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 your tool and battery caused by overloading or overheating. The cordless hydraulic driver is compatible with all Milwaukee® M12™ REDLITHIUM™ Compact Batteries or Extended Capacity Batteries, providing you 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 gives you greater control over output speed and power for greater versatility in a wide range of applications. Self-Tapping Screw Mode reduces walking when you are self-tapping screws as well as reduces overdriving, breaking and stripping out screws.
