Milwaukee Tool 2438-20 Cordless Disc Sander 3 in 12V

Product Description

The MILWAUKEE TOOL 2438-20 is a cordless handheld disc sander designed for grinding, sanding, and polishing tasks on the job site or in the shop. Running on a 12-volt platform, it accepts disc sizes from 2 inches up to 3 inches in diameter, giving technicians and tradespeople a compact, battery-powered abrasive tool that fits in tight spaces where larger angle grinders cannot. Its handheld form factor makes it practical for surface prep, deburring, and finishing work on metal, wood, and composite materials. Licensed electricians, HVAC techs, plumbers, and general tradespeople keep this class of tool on hand for field metalwork and surface finishing without needing a corded power source.

The 2438-20 is suited for residential and light commercial trade applications where portability and access to confined work areas matter. Typical use cases include deburring cut conduit, smoothing weld seams, prepping metal pipe ends, and light surface finishing on sheet metal or structural components. Because this unit ships as a tool-only package, it pairs with compatible MILWAUKEE TOOL M12 series batteries and chargers sold separately. It is appropriate for any trade professional already working within the M12 cordless ecosystem.
