Osborn 0004725100 Silicon Carbide Crimped Disc Brush 80 Grit

Product Description

The OSBORN 0004725100 is a silicon carbide crimped disc brush designed for surface conditioning, deburring, and finishing on hard metals, composites, and non-ferrous materials. Built with a quick-change connector and a 1/4-inch shank diameter, it mounts easily to compatible rotary tools and CNC machines without additional hardware. The brush measures 1.5 inches in outside diameter with a 1.375-inch trim length and operates at up to 4,500 RPM. At 80 grit medium grade, it delivers controlled material removal suited for precision finishing work in production and maintenance environments.

This disc brush is well suited for CNC machining centers and handheld rotary tools where consistent surface prep is required. Typical applications include edge blending, scale removal, weld cleanup, and light deburring on machined parts. The quick-change connector reduces changeover time during high-volume operations. It is commonly installed by machinists, fabricators, and maintenance technicians working in industrial and manufacturing settings.

Key Features

• Black brush color aids in visual inspection during use

Compatibility

Designed for use with CNC machines and rotary tools that accept a 1/4-inch shank with a quick-change connector system.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with rotary abrasive tooling. Always power down and lock out the machine before mounting or removing the brush. Verify that the spindle speed does not exceed the 4,500 RPM maximum rating before operation. Wear appropriate eye protection and follow all applicable shop safety protocols when using rotary abrasive tools.
