Weiler 94667 Knotted Wheel Brush 6-7/8 in Stainless Steel

Product Description

The WEILER 94667 is a knotted wire wheel brush designed for aggressive surface preparation, weld cleaning, and rust or scale removal on metal workpieces. Built with stainless steel stringer bead twist wire, it delivers consistent cutting action without contaminating stainless steel or aluminum base materials. The brush measures 6.875 inches in outside diameter with a 3/16 inch face width and is rated to 9,000 RPM, making it suitable for angle grinders and bench grinders used in fabrication, welding, and industrial maintenance environments. Installation requires a 5/8-11 threaded arbor. No shank is included. Licensed tradespeople and industrial technicians are the primary users of this tool.

This wheel brush is used in metalworking, welding shops, and maintenance applications where knotted wire action is required to clean weld beads, remove mill scale, or prep surfaces for coating. It is appropriate for both ferrous and non-ferrous applications where stainless steel fill material prevents cross-contamination. Typical install scenarios include pre-weld and post-weld cleanup on structural steel, pipe, and sheet metal in commercial and industrial settings.

Key Features

• Knotted stringer bead twist wire for aggressive, consistent surface cutting action
• Stainless steel fill material prevents contamination on stainless and aluminum substrates
• 6.875 inch outside diameter with 3/16 inch face width for focused contact area
• 9,000 RPM maximum speed rating for compatibility with common angle grinders
• 5/8-11 threaded arbor hole for secure, direct mounting — no shank required
• 1.125 inch trim length for extended service life before wire fatigue

Compatibility

Designed for use on angle grinders and bench grinders with a 5/8-11 threaded arbor. Verify that the grinder's no-load RPM does not exceed 9,000 RPM before mounting.

Installation Notes

Installation should be performed by qualified operators familiar with abrasive wheel safety. Always power down and disconnect the grinder before mounting or removing the brush. Confirm the tool's rated speed does not exceed the 9,000 RPM maximum marked on the brush — operating above rated speed is a serious safety hazard. Eye protection, face shield, and appropriate PPE are required during operation per ANSI B11 and tool manufacturer guidelines.
