Osborn 0003087200 End Brush Ceramic Crimped Wire 120 Grit

Product Description

The OSBORN 0003087200 is a ceramic-fill end brush designed for aggressive surface finishing, deburring, and cleaning on metal and composite workpieces. The crimped wire configuration uses premium ceramic filaments to deliver consistent cut and long service life. The brush measures 0.5 inches in diameter and is rated to a maximum of 9,000 RPM, making it suitable for use with standard die grinders, rotary tools, and drill press applications. A removable plastic bridle controls flare during use, and the shank is included for direct chuck mounting. The fine grade, 120 grit ceramic fill is well suited to controlled material removal and surface preparation tasks where a consistent scratch pattern is required.

This end brush is used in metalworking, fabrication, and maintenance applications where a technician needs to reach into bores, ports, weld seams, or recessed cavities. The flared, bridled design with a filled ceramic medium is a common choice for pipe prep, casting cleanup, and general surface conditioning in industrial and light manufacturing environments. The included shank allows direct installation into standard rotary tool chucks without additional adapters.

Installation Notes

Installation and operation of this brush should be performed by a qualified machinist or maintenance technician familiar with rotary abrasive tooling. Confirm the tool spindle speed does not exceed the 9,000 RPM maximum rating before mounting. Secure the shank fully in the chuck and ensure the chuck key is removed before starting the tool. Eye protection and appropriate PPE are required when operating any rotary brush at speed.
