Norton 66252838877 End Brush 1/2 in Carbon Steel Knotted

Product Description

The NORTON 66252838877 is a knotted wire end brush designed for aggressive surface preparation and cleaning on metal, welds, and castings. Measuring 1/2 inch in brush diameter, it accepts a 1/4-inch pilot shank that is 1-1/2 inches long, allowing it to mount in standard rotary tools, die grinders, and drill chucks. The carbon steel fill wire runs in the 0.0101 to 0.0200 inch diameter range and is rated for a maximum of 22,000 RPM. Its coarse grade makes it well suited for deburring, rust removal, and weld splatter cleanup. HVAC technicians, pipefitters, welders, and general maintenance trades routinely use this style of brush for fast material removal in tight or recessed areas.

This end brush is used in both residential and light commercial maintenance applications where a small-diameter rotary brush is needed to reach bores, ports, tube ends, pipe interiors, or recessed weld joints. It is a single-unit, non-bridled, non-encapsulated brush with no flared filaments, keeping the wire action focused and consistent throughout the tool life. It is sold and packaged as a single brush.

Installation Notes

Always confirm the spindle speed of the host tool does not exceed 22,000 RPM before mounting this brush. Disconnect power or remove the battery from the tool before installing or removing the brush. Wear appropriate eye protection and a face shield during operation, as wire bristles can dislodge under load. Inspect the brush for damaged or loose wires before each use and replace if any are found.
