Weiler 93806 Brass End Brush

The Weiler 93806 is a crimped wire end brush designed for use with straight grinders, drills, impact drivers, and pencil grinders. It features a 1/4 inch round shank for secure chucking in compatible power tools. This brush targets metalworkers and maintenance technicians needing to clean or deburr internal surfaces and hard-to-reach areas.

Brass Wire Performance Under Load

Crimped brass wires measuring 0.005 inch in diameter provide flexible brushing action that conforms to irregular contours without excessive aggression. The brass construction resists sparking and avoids contaminating non-ferrous workpieces during extended sessions. Rated for a maximum operating speed of 25,000 RPM, the brush maintains integrity under sustained high-speed rotation.

1/2 Inch Brush Diameter Constraint

A brush diameter of 1/2 inch defines the maximum contact area and determines access to confined bores or recesses. The 7/8 inch bristle length and 2 1/2 inch overall length set the reach envelope for internal cleaning tasks. Buyers needing wider surface coverage or deeper cavity access should verify these dimensions against their specific application requirements.

Questions about this item

How much heat does the brass wire generate when the brush runs continuously at 25,000 RPM?

Brass conducts heat well, so the crimped wire stays cooler than steel under the same speed and load.

What shank size must my tool accept to mount this 1/4 in round shank?

The tool chuck or collet needs a 1/4 in opening to hold the round shank securely.

Will the 0.005 in brass wire damage the softer brass fittings I keep on older projects?

The fine brass wire is softer than the base brass, so it cleans without gouging the fittings.
