Milwaukee 2658-20 M18 3/8 Inch Cordless Impact Wrench

Product Description

The Milwaukee Electric Tool Corp 2658-20 is a cordless impact wrench built for the M18 18-volt battery platform. It accepts a 3/8 inch drive and delivers the rotational force needed to drive and remove fasteners on mechanical, HVAC, plumbing, and general trade applications. The tool-only configuration means no battery or charger is included, making it a practical addition for techs already running M18 equipment. Its compact impact mechanism reduces hand fatigue during extended overhead or confined-space work, and the 3/8 inch drive size suits the mid-range fastener applications common in equipment installation and service.

This impact wrench fits naturally into residential and light commercial service work. HVAC technicians use 3/8 inch drive tools for equipment panels, motor mounts, and condensing unit hardware. Plumbers and pipefitters reach for this size when working with fixture carriers, valve flanges, and equipment anchoring. Electricians use it for panel mounting hardware and strut work. The cordless M18 platform removes the need for an air compressor or hose on the job site, improving mobility in tight mechanical rooms and rooftop equipment areas.
