Norton 66252839043 End Brush 1/2 in Stainless Steel Crimped Wire

Product Description

The NORTON 66252839043 is a stainless steel crimped wire end brush designed for rotary tool and die grinder applications. It mounts via a 1/4-inch pilot shank and delivers coarse-grade abrasive action for deburring, surface prep, weld cleaning, and rust removal on metal workpieces. The crimped wire construction allows the filaments to flex on contact, making it effective on irregular surfaces and hard-to-reach areas. Rated to a maximum of 25,000 RPM, it is suited for high-speed rotary tools commonly used by machinists, fabricators, and maintenance technicians working in industrial and manufacturing environments.

This end brush is used in metalworking applications where controlled surface finishing or cleaning is required in confined spaces or on internal bores and recesses. The 1/2-inch brush diameter and 1-1/2-inch shank length make it compatible with standard die grinders and rotary tools that accept a 1/4-inch shank. It is well-suited for light deburring, cleaning weld seams, and preparing metal surfaces prior to coating or inspection in fabrication shops and maintenance settings.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using standard die grinders or rotary tools. Always power down and disconnect the tool from its power source before mounting or removing the brush. Ensure the tool collet is tightened securely to the shank before operation, and verify that the tool's rated RPM does not exceed the 25,000 RPM maximum rating of the brush. Always wear appropriate personal protective equipment including eye protection when operating wire brushes at high speed.
