Osborn 0004725700 Silicon Carbide Crimped Disc Brush 120 Grit

Product Description

The OSBORN 0004725700 is a 2-inch silicon carbide crimped disc brush designed for surface conditioning, deburring, and finishing applications on metal, composites, and other hard materials. Fitted with a quick-change connector and a 1/4-inch shank diameter, the brush mounts easily to compatible rotary tools and CNC machines without additional adapters. The crimped filament construction provides consistent abrasive contact across irregular surfaces, and the 120-grit silicon carbide abrasive delivers a fine-grade cut suited to light material removal and surface prep. Maximum operating speed is 4500 RPM. Filament diameter is 0.040 inches, and trim length is 1.375 inches.

This disc brush is used in machine shops, fabrication facilities, and maintenance environments where controlled surface finishing is required. Its quick-change connector and 1/4-inch shank make it compatible with CNC machine spindles and handheld rotary tools configured for that connection type. Typical applications include edge deburring after machining, weld seam blending, and surface oxide removal on ferrous and non-ferrous workpieces. The black silicon carbide filaments are well-suited for harder substrate materials that require a sharper abrasive than aluminum oxide.

Key Features

• 120-grit silicon carbide abrasive for fine-grade surface finishing and light deburring
• Crimped round filaments maintain consistent abrasive contact on contoured and flat surfaces
• Quick-change connector allows fast tooling swaps without additional hardware
• 1/4-inch shank diameter fits standard rotary tool and CNC spindle collets
• Rated to 4500 RPM for use at typical machine operating speeds
• 1.375-inch trim length provides controlled flex and filament durability

Compatibility

Designed for use with CNC machines and rotary tools accepting a 1/4-inch quick-change shank connection.

Installation Notes

This brush is installed by a machinist or maintenance technician familiar with rotary abrasive tooling. Always confirm the spindle or tool RPM rating meets or exceeds the 4500 RPM maximum before mounting. Power down and de-energize the machine fully before changing brush tooling. Do not exceed the rated maximum RPM, and inspect the filaments for wear or damage before each use.
