Milwaukee 2855P-20 M18 FUEL 1/2" Compact Impact Wrench, Pin Detent

Milwaukee 2855P-20 M18 FUEL 1/2" Compact Impact Wrench, Pin Detent

The Milwaukee 2855P-20 is a 1/2" compact impact wrench from the M18 FUEL series, built for professionals who need high-torque fastening performance in tight, hard-to-reach spaces. Designed around the M18 battery platform, this compact impact wrench pairs with Milwaukee's M18 system of interchangeable batteries and chargers, giving trade professionals a consistent power source across their tool lineup. The 2855P-20 features Pin Detent socket retention, which locks sockets onto the anvil to help prevent them from slipping off mid-task — a detail that matters when working overhead, in confined bays, or on ladders and lifts. Its compact footprint is engineered specifically for clearance-limited fastening work where a standard full-size impact wrench simply won't fit.

Key Features

• 1/2" Compact Impact Wrench: A right-sized anvil and body designed for tight-clearance fastening tasks in automotive, industrial, and structural settings where space is limited.
• M18 FUEL Series: Part of Milwaukee's M18 FUEL lineup, built to run on the M18 battery platform shared across Milwaukee's M18 tool ecosystem.
• Pin Detent Retention: A pin-style detent secures sockets onto the anvil, helping keep them seated during use and reducing lost time from dropped or slipped sockets.
• Compact, Maneuverable Body: Sized to fit into confined work areas — wheel wells, engine bays, equipment housings, and other restricted spaces — without sacrificing fastening capability.
• Model 2855P-20: Milwaukee's designated model number for this configuration of the M18 FUEL 1/2" compact impact wrench with Pin Detent.

Why Milwaukee?

Milwaukee built the M18 FUEL line around a shared M18 battery platform, so professionals can move a single set of batteries and chargers across an entire lineup of compatible tools rather than managing multiple incompatible systems. The 2855P-20's compact 1/2" sizing and Pin Detent socket retention reflect that same focus on practical jobsite performance — a tool sized and equipped for the tight-clearance, high-torque fastening work that professional trades encounter daily. For technicians and contractors already invested in the M18 platform, the 2855P-20 extends that ecosystem with a dedicated compact impact wrench built for the job.
