Weiler 94038 Knot Wire Wheel Brush

The Weiler 94038 is a stainless-steel knot wire wheel brush designed for die grinders. It features a 1/4-inch round shank and a 3-1/4-inch diameter with a 3/8-inch face width. Standard twist knots use .014-inch wire for aggressive surface preparation on stainless steel.

Suited for metalworkers cleaning welds

This brush suits operators who need a compact wheel for tight areas on stainless steel. It is not for users requiring wider face widths, longer bristle lengths, or tools that cannot accept a 1/4-inch shank. Buyers needing lower maximum speeds should verify equipment compatibility before purchasing.

Stem mount enables quick changes on die grinders

The round shank fits directly into compatible collets without additional adapters. Stainless-steel bristles resist contamination when working on similar alloys. A 25,000 RPM maximum rating supports high-speed material removal in demanding applications.

Questions about this item

What size die grinder collet does the 1/4 in round shank require?

The brush fits a standard 1/4 in collet on any die grinder rated for at least 25,000 RPM.

Will the 0.014 in stainless knots damage softer metals I still machine?

The fine 0.014 in stainless knots clean aggressively but are gentle enough for aluminium and brass when used with light pressure.

How can I confirm the wheel is running true at 25,000 RPM after mounting?

Spin the brush briefly; a smooth, vibration-free hum and an even wire pattern show it is seated correctly and balanced.
