Disston Company 842677 Crimped Wire Cup Brush 3 in Fine

Product Description

The DISSTON COMPANY 842677 is a 3-inch utility crimped wire cup brush designed for surface prep work including smoothing, cleaning, and polishing on metal and other hard materials. The brush mounts via a 1/4-inch shank, making it compatible with standard electric drills and drill presses. Wire diameter is .008 gauge, placing this in the fine category for applications where a lighter touch is needed to avoid deep scoring. Maximum rated speed is 3,000 RPM. Installed by electricians, HVAC technicians, plumbers, and general tradespeople for cleaning pipe ends, removing rust or scale, and prepping weld zones before or after work.

This cup brush suits both bench-mounted drill presses and handheld power drills equipped with a 1/4-inch chuck or collet. It is appropriate for light-to-medium deburring, corrosion removal, and surface conditioning on steel pipe, conduit, fittings, and structural metal. Its crimped wire configuration allows the bristles to flex under load, which reduces gouging and suits contoured or irregular surfaces common in mechanical and electrical trade work. Typical use environments include shop fabrication, field service, and maintenance settings.

Installation Notes

A licensed electrician or qualified tradesperson should ensure the drill or drill press is fully de-energized and the chuck is secured before mounting or removing this brush. Never exceed the 3,000 RPM maximum rated speed. Wear appropriate eye protection and work gloves when operating wire brushes, as wire bristles can shed under load. Inspect the brush for broken or missing wires before each use and replace if damage is found.
