Weiler 94632 Knotted Wire Wheel Brush 4 Inch Carbon Steel

Product Description

The WEILER 94632 is a knotted wire wheel brush designed for aggressive surface preparation, weld cleaning, and rust or scale removal. Mounted via an arbor hole, this brush fits standard bench grinders and angle grinders used by fabricators, ironworkers, pipefitters, and maintenance technicians. The carbon steel wire construction handles heavy-duty deburring and surface conditioning tasks at a maximum rated speed of 20,000 RPM. At 4 inches in outside diameter with a 0.5-inch face width and a 0.875-inch trim length, it delivers focused cutting action on metal workpieces in shop and field environments.

This wheel brush is suited for use on ferrous metals including structural steel, pipe, weldments, and fabricated components. It is a standard tool on job sites and in fabrication shops where weld spatter, mill scale, corrosion, and burrs must be removed before coating, inspection, or assembly. The knotted wire configuration with standard twist knots provides greater aggressiveness than crimped wire brushes, making it the appropriate choice for heavy contamination and harder base materials.

Key Features

• Knotted carbon steel wire with standard twist knots for aggressive material removal
• 4-inch outside diameter with 0.5-inch face width for focused brush contact
• Rated to 20,000 RPM for use on high-speed angle grinders and bench grinders
• Arbor hole mount — no shank included, fits standard arbor-style grinder spindles
• 0.875-inch trim length provides consistent wire tension and controlled cut
• Filament wire diameter in the 0.010 to 0.019-inch range for heavy-duty surface work

Compatibility

Designed for use with arbor-hole-style bench grinders and right-angle grinders that accept a 4-inch wheel brush. Verify spindle thread size and arbor bore before installation.

Installation Notes

Installation is performed by qualified trades personnel familiar with angle grinder and bench grinder safety. Always power down and disconnect the grinder before mounting or removing the brush. Confirm the grinder RPM rating meets or exceeds the 20,000 RPM maximum rating of the brush before operation. Wear appropriate PPE including eye and face protection, as wire wheel brushes can shed filaments at operating speed.
