Osborn 0007567700 End Brush Brass Crimped Wire Fine

Product Description

The OSBORN 0007567700 is a miniature wire end brush designed for precision cleaning, deburring, and surface preparation in tight or small-diameter areas. Built with fine-grade crimped brass wire, it delivers gentle yet effective scrubbing action without scratching or damaging delicate base materials. The 0.25-inch brush diameter and crimped wire fill make it well-suited for reaching into bores, ports, and recesses where larger brushes cannot fit. With a maximum rated speed of 25,000 RPM, it is compatible with high-speed rotary tools and die grinders. A shank is included for direct tool chuck mounting. Technicians across HVAC, plumbing, electrical, and light industrial trades use this brush for cleaning fittings, ports, valve seats, and threaded openings.

This end brush is intended for use on delicate parts and assemblies where brass wire is appropriate to avoid material damage. Typical applications include cleaning copper tubing ends, electrical contact points, small threaded fasteners, valve bodies, and similar components. The fine crimp pattern allows the wire to conform lightly to surface irregularities, improving contact across uneven geometry. It is packaged individually and sized for use with standard rotary tools, die grinders, and drill presses.

Installation Notes

Installation and operation should be performed by qualified technicians familiar with rotary abrasive tooling. Always confirm the tool spindle speed does not exceed the 25,000 RPM maximum rating before mounting. Secure the shank fully in the chuck and inspect the brush for damaged or splayed wire before each use. Wear appropriate eye protection and follow applicable workplace safety standards when operating rotary wire brushes.
