Weiler 98435 Cup Brush 5/8 in Stainless Steel Crimped 37000 Rpm

Product Description

The WEILER 98435 is a miniature stainless steel cup brush designed for use with rotary tools and die grinders. It features crimped stainless steel wire fill with a wire diameter of 0.005 inches, delivering consistent surface contact for light deburring, cleaning, and surface prep on metal workpieces. The brush measures 5/8 inches in diameter with a 1/4 inch trim length and an overall length of 2 inches. A 1/8 inch shank arbor type allows direct chuck mounting on standard rotary tools. Rated to a maximum of 37,000 RPM, this brush suits high-speed applications where a compact profile is required. Maintenance technicians and fabricators commonly reach for this size when working in confined areas or on small-diameter pipe, tubing, or fittings.

This cup brush is suited for light-duty surface preparation tasks including weld cleaning, rust removal, paint stripping, and oxidation removal on stainless steel, aluminum, and other metals. Its small diameter and high RPM rating make it a practical choice for detail work on equipment, fittings, and assemblies in HVAC, plumbing, and general mechanical maintenance applications. The stainless steel wire fill resists contamination and is appropriate for use on stainless substrate materials where carbon steel wire is not acceptable.

Installation Notes

This brush is installed by inserting the 1/8 inch shank directly into a compatible rotary tool or die grinder chuck and tightening securely before operation. Always confirm the tool RPM rating meets or exceeds the brush maximum RPM of 37,000 before use. Wear appropriate eye protection and gloves when operating wire brush attachments at high speed. Inspect the brush for damaged or splayed wire fill before each use and replace if wear is evident.
