Osborn 0007569800 Nylon End Brush 5/16 in 600 Grit

Product Description

The OSBORN 0007569800 is a miniature ATB end brush designed for light-duty cleaning and surface finishing applications. It features premium nylon filaments impregnated with aluminum oxide abrasive, rated at a super fine 600 grit. The brush measures 5/16 inch in diameter and comes with a shank included for direct mounting in a rotary tool, drill, or die grinder. Rated for up to 6,000 RPM, this end brush delivers controlled, consistent abrasive action on delicate surfaces. It is well suited for deburring, cleaning, and surface prep in tight or contoured areas where a larger brush cannot reach. Weight is approximately 0.12 pounds per unit.

This end brush is used across a broad range of trade and industrial applications including light surface conditioning, weld cleanup on thin materials, cleaning ports and small bores, and finish work in confined geometries. Its super fine grit and nylon filament construction make it appropriate for use on softer metals, composites, and finished surfaces where aggressive abrasive action would cause damage. Technicians and machinists working with precision components will find the small diameter and high RPM rating practical for detailed work.
