Weiler 94052 Knotted Wheel Brush 4.5 in Stainless Steel

Product Description

The WEILER 94052 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 on surfaces where contamination from carbon steel is not acceptable. The wheel measures 4.5 inches in outside diameter with a 3/16-inch face width and a 7/8-inch trim length. The threaded 5/8-11 arbor hole mounts directly to standard angle grinders and bench grinder spindles without an additional shank. It is rated to 12,500 RPM, making it suitable for use on most 4.5-inch right-angle grinders at full operating speed.

This wheel brush is used in metalworking, fabrication, and maintenance applications where weld spatter, mill scale, corrosion, or surface contaminants must be removed. Stainless steel fill wire makes it the correct choice when working on stainless steel, aluminum, or other materials that require contamination-free wire to prevent cross-contamination or surface discoloration. Typical users include welders, pipefitters, millwrights, and maintenance technicians working in industrial, commercial, and light manufacturing environments.

Installation Notes

Installation should be performed by a qualified operator following the grinder and accessory manufacturer guidelines and applicable ANSI B11 or OSHA abrasive wheel standards. Always power down and disconnect the grinder before mounting or removing the wheel brush. Verify that the tool spindle speed does not exceed the 12,500 RPM maximum rating stamped on the wheel. Inspect the brush for damaged or loose wire before each use and wear appropriate eye, face, and hand protection during operation.
