Weiler 94645 Knotted Wheel Brush 6 Inch Stainless Steel

Product Description

The WEILER 94645 is a knotted wire wheel brush designed for aggressive surface preparation, weld cleaning, rust removal, and scale removal on metal workpieces. The brush features stainless steel wire in a standard twist knot configuration, mounted via a 5/8 inch arbor hole. Rated to 9,000 RPM, it is built for use on angle grinders and bench grinders in industrial, fabrication, and maintenance applications. The 6 inch outside diameter and 1/2 inch face width provide focused contact on workpiece surfaces. Licensed tradespeople and fabricators install and operate this brush in metal finishing workflows.

The WEILER 94645 is suited for use in metal fabrication shops, welding operations, structural steel work, and general industrial maintenance environments. It is appropriate for both production and field service settings where stainless steel wire is required to avoid carbon contamination on stainless steel or aluminum base materials. The 1-3/8 inch trim length provides consistent wire projection throughout the service life of the brush.

Compatibility

Designed for use with angle grinders and bench grinders equipped with a 5/8 inch arbor hole. Verify that the grinder nameplate RPM rating meets or exceeds the brush maximum RPM before installation.

Installation Notes

Always power down and disconnect the grinder from its power source before mounting or removing the brush. Confirm the arbor hole fits the grinder spindle without forcing. Operators should wear appropriate eye, face, and hand protection during use, as wire bristles can fracture and become projectiles at operating speed. Never exceed the 9,000 RPM maximum speed rating marked on the brush.
