Osborn 0007571000 Cup Brush 9/16 in Stainless Steel

Product Description

The OSBORN 0007571000 is a miniature cup brush designed for deburring, cleaning, and surface preparation in tight or confined areas. It features a straight shank mount with a 1/8 inch shank diameter, making it compatible with rotary tools, die grinders, and similar handheld power tools. The brush fill is stainless steel wire at 0.005 inches in diameter, suited for work on stainless steel, aluminum, and other metals where carbon steel wire would risk contamination. Rated to 25,000 RPM, it handles high-speed tool spindles without issue. HVAC technicians, pipefitters, and fabricators commonly use brushes like this for tube end prep, weld bead cleanup, and oxide removal before brazing or fitting connections.

This cup brush is well-suited to residential and light commercial trade applications where small-diameter rotary accessories are required. Typical use cases include cleaning burrs from cut copper or stainless tubing, removing oxidation from fittings prior to solder or braze joints, and light surface conditioning in areas inaccessible to larger abrasive tools. The 9/16 inch brush diameter fits standard rotary tool chucks and small die grinder collets with a 1/8 inch shank capacity.

Installation Notes

Installation and operation should be performed by a qualified technician familiar with rotary abrasive tooling and applicable workplace safety standards. Always verify the tool spindle speed does not exceed the 25,000 RPM rating of the brush before use. Secure the shank fully in the collet or chuck and confirm the accessory is locked before operating. Wear appropriate eye protection and hand protection when using any rotary wire brush.
