Weiler 10218 Knot Wire End Brush 0.5 in Stainless 10 Pack

Product Description

The WEILER 10218 is a knot wire end brush designed for aggressive surface preparation, deburring, and weld cleaning on metal workpieces. Built with stainless steel bristles, this brush delivers consistent cut and long service life on stainless steel base materials and other metals where carbon contamination must be avoided. The 0.5 inch brush diameter and 0.014 inch wire diameter make it well suited for detail work in confined areas, and the 20000 RPM maximum speed rating gives it broad compatibility with standard die grinders and rotary tools used in mechanical and fabrication environments.

This end brush is commonly used by HVAC technicians, pipe fitters, welders, and sheet metal workers for cleaning weld joints, removing mill scale, and preparing mating surfaces before brazing or soldering. The knot wire construction provides more aggressive action than crimped wire, making it effective on heavier scale and rust. Each box contains 10 brushes, supporting regular bench stock for service fleets or fabrication shops with high consumption rates.

Installation Notes

Installation and use of wire end brushes should follow ANSI B165.1 safety standards and the tool manufacturer guidelines for maximum operating speed. Always verify the tool RPM rating does not exceed the 20000 RPM maximum before mounting. Wear appropriate personal protective equipment including eye and face protection, as wire bristles can detach during use. Inspect the brush for damaged or missing wires before each use and replace if defects are found.
