Walter Surface Technologies 13C065 Cup Brush 1-1/2 in

Product Description

The WALTER SURFACE TECHNOLOGIES 13C065 is a 1-1/2 inch diameter crimped cup brush designed for surface preparation, deburring, and weld cleaning on metal workpieces. Filled with stainless steel wire at 0.0118 inches in diameter, the crimped fill pattern provides consistent contact pressure and flexibility across irregular surfaces. The brush operates at a maximum of 13,000 RPM and mounts via a 1/4 inch diameter shank, making it compatible with standard die grinders and rotary tools. Fabricators, welders, pipefitters, and maintenance technicians use this type of brush for removing mill scale, rust, paint, and light oxidation without contaminating carbon steel or sensitive base materials.

This cup brush is suited for light to medium surface conditioning tasks in fabrication shops, field maintenance, and MRO applications. Its stainless steel fill makes it the correct choice when working on stainless steel, aluminum, or other materials where cross-contamination from carbon steel wire must be avoided. The 1/4 inch shank fits directly into die grinders, inline grinders, and drill chucks commonly found in both shop and field environments.

Installation Notes

Installation and operation should follow ANSI safety standards for abrasive and wire brush products. Ensure the grinder is powered off and disconnected before mounting or removing the brush. Thread the 1/4 inch shank fully into the collet and tighten securely before operating. Always verify the tool's free-speed RPM does not exceed the brush's 13,000 RPM maximum rating, and wear appropriate eye and face protection during use.
