Osborn 0002604800 Knotted Wire Wheel Brush 6.5 in

Product Description

The OSBORN 0002604800 is a knotted wire wheel brush designed for aggressive material removal on metal surfaces. The 6.5-inch outside diameter wheel features stringer bead twist wire knots made from steel fill material, delivering consistent cutting action across weld spatter, rust, scale, and burrs. Rated to 12,000 RPM, it is built for use with pneumatic angle grinders and electric power tools. The threaded arbor hole accepts a 5/8-11 arbor, with no shank included. Licensed trades and fabrication professionals specify this brush for surface prep work where consistent wire geometry and durability are required.

This wheel brush suits a wide range of surface preparation applications including weld cleaning, rust and scale removal, and general deburring on structural steel, pipe, plate, and fabricated assemblies. The stringer bead wire configuration concentrates contact force for faster stock removal compared to crimped-wire designs. It is commonly used in industrial, commercial, and trade settings where air tools or corded grinders provide the drive. The 0.25-inch face width keeps the working area focused, making it well-suited for groove cleaning, weld seam prep, and tight-profile work.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive wheel safety. Always power down and de-energize the drive tool before mounting or removing the brush.

Operators should wear appropriate PPE including face shield, gloves, and hearing protection when running wire wheel brushes at speed.
