Osborn 0004725400 Crimped Disc Brush 320 Grit 1-1/2 in

Product Description

The OSBORN 0004725400 is a 1-1/2 inch silicon carbide crimped disc brush rated at 320 grit for extra fine surface finishing. It features a quick-change connector and a 1/4 inch shank diameter, making it suitable for fast tooling swaps in production and maintenance environments. The crimped round filaments measure 0.022 inches in diameter and provide consistent, even contact across the work surface. With a maximum operating speed of 4,500 RPM, this brush is built for controlled, precision finishing passes. Machinists, fabricators, and maintenance technicians use this type of brush for deburring, surface prep, and light stock removal on metals and composites.

This disc brush is designed for use in CNC machine applications where quick tooling changes and consistent abrasive performance are required. The silicon carbide abrasive material is well suited to non-ferrous metals, ceramics, and hard materials where aggressive cutting action is not needed. The extra fine 320 grit delivers a smooth finish with minimal material removal, making it appropriate for final-stage surface conditioning. The 1-3/8 inch trim length provides adequate reach for standard disc brush applications in automated or handheld rotary setups.

Installation Notes

This brush is installed by a machinist or maintenance technician using the quick-change connector on a compatible rotary spindle or CNC tool holder. Always power down and de-energize the machine before mounting or removing the brush. Do not exceed the rated maximum of 4,500 RPM during operation. Inspect the filaments for wear or deformation before each use and replace if the brush shows signs of uneven wear or filament loss.
