Osborn 0001140200 Wheel Brush 1-1/2 in Crimped Nylon 320 Grit

Product Description

The OSBORN 0001140200 is a 1-1/2 inch diameter wheel brush designed for surface finishing, deburring, and blending applications. It uses crimped nylon filaments impregnated with 320-grit silicon carbide abrasive, making it well suited for light material removal and surface conditioning on metal, wood, or composite substrates. The brush mounts via a 1/2 inch arbor hole and carries a maximum rated speed of 20,000 RPM. A face width of 1/4 inch and a trim length of 1/4 inch give it a compact profile for precision work in tight areas. Machinists, fabricators, and maintenance technicians are the typical installers and operators of this tool.

This wheel brush is used in bench grinder, drill press, and rotary tool setups where a controlled abrasive action is needed without aggressive stock removal. The 320-grit silicon carbide fill produces a fine finish appropriate for pre-polish prep, light scale removal, and cleaning weld seams on ferrous and non-ferrous metals. Its small diameter makes it practical for detail work and component finishing in both shop and field maintenance settings.
