Crimped brass end brush

The Weiler 93804 is a crimped wire end brush built for detail work on brass surfaces. It fits straight grinders, drills, impact drivers and pencil grinders that accept a 1/4 in round shank. The brush reaches a maximum speed of 22,000 RPM and measures 1 in across the bristle face with a 1 in trim length.

Build fit and clearance

The 1/4 in shank slips into standard collets and chucks without adapters. At 3 in overall length the brush keeps the motor housing clear of the workpiece on flat or contoured parts. Brass wire is softer than steel so it removes oxidation and light coatings without gouging the base metal.

Suited for light deburring and polishing

Users cleaning brass fittings, electrical contacts or decorative hardware will find the crimped wire compliant and non-sparking. Builders needing aggressive stock removal on hardened steel or heavy rust should choose a stiffer wire type. The brush is not intended for high-volume production lines that demand continuous-duty rated tools.
