Norton 66252839110 Cup Brush 2in Carbon Steel Crimped

Product Description

The NORTON 66252839110 is a crimped carbon steel cup brush designed for surface preparation, deburring, and scale removal on metal workpieces. Measuring 2 inches in diameter with a 0.012-inch wire diameter, this brush mounts via a 1/4-inch shank and is rated for use up to 13,000 RPM. The crimped fill configuration provides moderate, consistent contact pressure across the work surface, making it well suited for cleaning welds, removing rust, and blending light surface irregularities. It is typically used with angle grinders or drill presses equipped with a compatible chuck or collet.

This cup brush is appropriate for light-to-medium metalworking tasks in fabrication shops, maintenance facilities, and field service environments. The 1/4-inch shank allows direct mounting in standard drill chucks and die grinders without additional adapters. The 5/8-inch trim length gives the filaments enough flex to conform to irregular surfaces while maintaining aggressive cutting action. Typical installers and users include welders, pipefitters, millwrights, and general maintenance technicians.

Compatibility

Designed for use with angle grinders, die grinders, and drill presses accepting a 1/4-inch shank. Verify that the tool spindle speed does not exceed 13,000 RPM before mounting.

Installation Notes

Always power down and disconnect the tool from its power source before mounting or removing the brush. Confirm the tool chuck or collet is rated for the shank diameter and that the tool maximum RPM does not exceed the brush rating of 13,000 RPM. Operators should wear appropriate PPE including safety glasses or a face shield and gloves, as wire filaments can shed during use. Follow OSHA and ANSI B11 abrasive tool safety guidelines when operating rotary wire brushes.
