Walter Surface Technologies 13C130 Knotted Wheel Brush

Product Description

The WALTER SURFACE TECHNOLOGIES 13C130 is a knotted steel wheel brush designed for aggressive surface preparation and weld cleaning on metal workpieces. Mounted via a 1/4-inch shank included with the brush, it installs directly into a die grinder for fast material removal. The 13C130 is rated to 25,000 RPM, making it suitable for high-speed finishing passes without sacrificing brush integrity. Cable-twist wire knots deliver concentrated, consistent contact across the work surface. The 2-3/4-inch outside diameter and 3/8-inch face width provide a narrow, focused cleaning path suited to welds, joints, and tight profiles. HVAC fabricators, pipefitters, ironworkers, and sheet metal mechanics are the typical end users for this type of tooling.

This wheel brush is built for use on steel surfaces and is compatible with die grinders accepting a 1/4-inch shank. It is well suited to weld spatter removal, scale cleaning, surface deburring, and pre-weld joint prep on mild steel, structural steel, and similar ferrous materials. The cable-twist knot construction maintains wire tension under load, extending brush life in sustained grinding applications. Sold individually.

Compatibility

Designed for use with die grinders accepting a 1/4-inch shank. Rated for steel material applications. Verify tool RPM rating meets or exceeds 25,000 RPM before use.

Installation Notes

Installation is performed by threading or inserting the 1/4-inch shank into a compatible die grinder collet and securing per the tool manufacturer's instructions. Always confirm the tool's maximum RPM rating is at or above the brush's 25,000 RPM rating before operation. Wear appropriate PPE including face shield and gloves when operating wire brushes at speed. Inspect the brush for damaged or broken wires before each use and remove from service if wire loss is detected.
