Milwaukee 2855-20 M18 Fuel 1/2 in Compact Impact Wrench

Product Description

The Milwaukee Electric Tool Corp 2855-20 is a compact, cordless 1/2 inch impact wrench built on the M18 FUEL platform. It uses a friction ring anvil for fast socket changes in tight work environments. Designed for professional tradespeople — electricians, plumbers, HVAC techs, and mechanical contractors — this tool delivers high torque output in a compact form factor that fits into confined spaces where full-size impact wrenches cannot. The M18 FUEL designation indicates a brushless motor with battery-powered cordless operation, making it suitable for job sites without ready power access.

This impact wrench is suited for residential and light commercial service work, including fastening conduit fittings, pipe flanges, mechanical equipment mounts, and structural fasteners. It is commonly used during HVAC equipment installations, plumbing rough-in, and electrical panel or gear mounting where repetitive fastening with controlled torque is needed. The 1/2 inch drive size accommodates a wide range of standard impact sockets used across trades.
