Got metalwork that needs serious cleaning or deburring? Felton’s knotted wire end brushes are built for heavy-duty action. This pack comes with 10 brushes, each with a 1-inch diameter and a 1-inch trim, filled with tough .014-inch steel wire. The knotted design gives you a more aggressive scrub than crimped brushes—perfect for knocking off rust, scale, paint, weld spatter, or corrosion from metal surfaces, edges, and corners. They’re ideal for fabrication shops, automotive work, or DIY metal projects. Made to spin at high speeds—up to 25,000 RPM—they deliver fast, efficient material removal. The flared knots help contour into tight spots, so you get into grooves and angles easily. Use them with angle grinders, drills, or bench motors for cleaning, finishing, or prepping surfaces before painting or welding. Durable, reliable, and great value in a 10-pack. Whether you’re a pro or a serious hobbyist, these brushes will save you time and elbow grease. Just remember to wear safety gear and run them at 18,000 RPM or higher for best results!
