Weiler 94643 Knotted Wheel Brush 6 Inch Carbon Steel

Product Description

The WEILER 94643 is a knotted wire wheel brush designed for aggressive surface preparation, weld cleaning, rust removal, and scale removal on metal workpieces. Measuring 6 inches in outside diameter with a 1/2 inch face width and 1-3/8 inch trim length, it mounts via a 5/8 inch arbor hole to angle grinders and bench grinders. The carbon steel knotted wire construction with a standard twist knot pattern delivers high-impact abrading action at speeds up to 9,000 RPM. It is a standard tool in metal fabrication, welding, and industrial maintenance applications where fast stock removal or surface conditioning is required.

This wheel brush is suited for use on ferrous metals in fabrication shops, structural steel work, pipe preparation, and weld joint cleanup. The knotted wire configuration concentrates wire ends at contact points, making it effective on heavily oxidized, scaled, or rough-welded surfaces. Typical users include welders, pipefitters, ironworkers, and industrial maintenance technicians working on steel components requiring surface prep prior to painting, coating, or inspection.

Key Features

• 6 inch outside diameter with 1/2 inch face width for broad contact coverage
• Knotted carbon steel wire with standard twist knot for aggressive material removal
• 9,000 RPM maximum rated speed for use with common angle grinders and bench grinders
• 5/8 inch arbor hole for direct mounting — no shank included
• 1-3/8 inch trim length provides consistent wire engagement and brush life
• Filament wire diameter in the 0.010 to 0.019 inch range for heavy-duty abrading

Compatibility

Designed for use with angle grinders and bench grinders that accept a 5/8 inch arbor hole mount and operate at or below 9,000 RPM. Verify that the tool spindle speed does not exceed the brush maximum RPM rating before use.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with abrasive wheel safety. Always power down and disconnect or de-energize the tool before mounting or removing the brush. Confirm the tool spindle RPM does not exceed the 9,000 RPM maximum rated speed marked on the brush. Wear appropriate PPE including a face shield and leather gloves during installation and operation, in accordance with ANSI B7.1 and tool manufacturer guidelines.
