Osborn 0004786100 Ceramic Disc Brush 80 Grit 2 in

Product Description

The OSBORN 0004786100 is a 2-inch ceramic abrasive disc brush rated at 80 grit and classified as fine grade. It is designed for surface finishing, deburring, and blending operations on metal and composite workpieces. The brush features a quick-change connector for fast spindle mounting without additional tooling. Round ceramic filaments with a 0.055-inch diameter deliver consistent cut rate and long service life across repeated passes. This brush is suited for use by machinists, tool-and-die technicians, and CNC machine operators working in production or job-shop environments. The 1/4-inch shank diameter and 1-3/8-inch trim length are engineered for controlled, repeatable engagement at the workpiece surface.

The 0004786100 disc brush is intended for use on CNC machines and compatible rotary tool setups where a quick-change interface is present. It is well-suited for light deburring, edge blending, and surface conditioning on ferrous and non-ferrous metals. The fine-grade ceramic abrasive provides a controlled cut that works well in finish-pass applications where surface integrity must be maintained. This brush is typically deployed in automated or semi-automated machining cells but can also be run on manual spindle equipment that accepts a 1/4-inch shank with a quick-change connector.

Key Features

• 80 grit fine-grade ceramic abrasive filaments for controlled surface finishing and deburring
• Quick-change connector allows fast brush swaps without hand tools
• Round ceramic filaments at 0.055 inches in diameter for consistent contact and cut rate
• 1/4-inch shank diameter compatible with standard quick-change rotary spindles
• 1-3/8-inch trim length provides stable filament engagement at the workpiece
• Maximum operating speed of 4500 RPM for safe use in production environments

Compatibility

Designed for CNC machines and rotary spindle equipment that accept a 1/4-inch quick-change shank connector.

Installation Notes

Installation is performed by qualified machinists or tool-setup technicians. Disengage all power and confirm the spindle is fully stopped before mounting or removing the brush. Verify the machine spindle speed does not exceed 4500 RPM before operation. Inspect filaments for wear or damage before each use and replace the brush if filament length has diminished to a point that reduces effective trim contact.
