Disston Company 842622 Crimped Wire Cup Brush 2 in 1/4 Shank

Product Description

The DISSTON COMPANY 842622 is a 2-inch coarse utility crimped wire cup brush designed for aggressive surface preparation on metal, wood, and masonry. Fitted with a 1/4-inch shank, it mounts directly into standard drill chucks and drill presses without adapters. The brush runs at up to 4,500 RPM and uses .012-inch wire gauge bristles to deliver fast, consistent material removal. Electricians, pipefitters, and general maintenance technicians reach for this brush when prepping surfaces before welding, coating, or bonding. It strips paint, knocks off rust scale, and clears loose debris from joints, flanges, and weld seams in a single pass.

This cup brush is suited for both handheld electric drills and bench-mounted drill presses, making it a practical addition to a field or shop toolbox. It handles residential and light commercial maintenance tasks where surface cleanliness is critical before applying primers, pipe dope, flux, or protective coatings. The coarse crimped wire configuration bites into oxidized or painted surfaces quickly, reducing prep time on small-diameter pipe ends, fittings, and structural steel sections. It is commonly used in HVAC, plumbing, and general metalworking applications.
