About This Product

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 and allows for easy transport on a tool belt and easy fitting into a job site tool bag. The Milwaukee M12 FUEL 1/2 in. Hammer Drill is the Most Powerful Subcompact Drill Driver, the Most Compact in size, and providing the Fastest Speed Under Load. The Milwaukee POWERSTATE brushless motor delivers the most power for the capability to perform the widest variety of applications at high speed for unrivaled subcompact performance. At only 5.9 in. in length, this portable drill is the shortest solution in class offering most access into tight spaces. Milwaukee REDLINK PLUS Intelligence delivers top of the line thermal performance to give users the Fastest Speed Under Load in order to drill and drive faster than any other subcompact drill. Our M12 REDLITHIUM HIGH OUTPUT CP2.5 Battery Pack delivers 25% more power and runs 25% cooler vs our other M12 REDLITHIUM CP battery packs. This increased performance of the lithium-ion battery gives you the same power and runtime of an M12 REDLITHIUM XC battery in a lighter and more compact package.


  • FLUID-DRIVE hydraulic powertrain reduces metal on metal contact within the tool, delivering quieter operation, smoother performance and increased durability over a standard impact
  • Longer sustained torque delivers similar drive times in application as most 12-Volt impact drivers
  • Up to 2X quieter operation makes this tool ideal for occupied spaces
  • Compact head length and compact battery footprint gives more access than competitive impact drivers
  • POWERSTATE brushless motor delivers maximum power and long motor life
  • REDLINK PLUS intelligence prevents damage to the tool and battery due to overloading or overheating
  • REDLITHIUM batteries deliver more work per charge and more work over the life of the battery
  • Includes: (1) 2551-20 (tool-only), belt clip, (1) 3404-20, (2) high output 2.5Ah battery packs
