Norton 66252839028 Cup Brush 1-3/4 in Carbon Steel Crimped

Product Description

The NORTON 66252839028 is a crimped carbon steel cup brush designed for surface preparation, weld cleaning, rust removal, and scale removal on metal workpieces. It mounts via a 1/4-inch shank arbor, making it compatible with standard die grinders and rotary tools. The brush measures 1-3/4 inches in diameter with a wire diameter of 0.012 inches and a trim length of 3/4 inch. A maximum rated speed of 13,000 RPM suits high-speed rotary tool applications. Crimped wire fill provides a consistent, flexible cutting action suited to contoured or irregular surfaces. This tool is used by welders, fabricators, pipefitters, and general metalworkers.

This cup brush is intended for use with die grinders and similar handheld rotary tools across a wide range of metal surface preparation tasks. Typical applications include cleaning weld beads, removing mill scale, stripping light corrosion, and preparing surfaces for coating or inspection. It is well suited to both shop and field use in fabrication, maintenance, and repair environments where a compact, shank-mounted brush is required.

Installation Notes

Installation is performed by trade professionals including welders, fabricators, and maintenance mechanics. Before mounting, confirm the tool spindle speed does not exceed the 13,000 RPM maximum rating stamped on the brush. Secure the 1/4 inch shank firmly in the tool collet and verify it is fully tightened before operation. Always wear appropriate eye and face protection when operating wire brushes, as broken wire fragments can be ejected at speed.
