Osborn 0009912200 Cup Brush 2 in Silicon Carbide 180 Grit

Product Description

The OSBORN 0009912200 is a 2-inch diameter cup brush designed for surface preparation, deburring, and light abrasive finishing work. It uses silicon carbide fill material in a crimped configuration, which provides consistent abrasive contact across irregular or contoured surfaces. The brush is rated to a maximum of 5,000 RPM and mounts via a 1/4-inch shank for use in standard rotary tools, die grinders, and drill chucks. At 180 grit, it is suited for fine to medium surface conditioning rather than aggressive material removal. Weighing 0.18 pounds, it is a compact, single-piece consumable used by tradespeople and fabricators in light deburring, cleaning, and finishing applications.

This cup brush is appropriate for use on materials where silicon carbide abrasives perform well, including non-ferrous metals, ceramics, composites, and masonry surfaces. The crimped fill style makes it well suited for work on irregular surfaces or in areas where consistent pressure across the entire brush face is needed. It is commonly used in HVAC, plumbing, and general fabrication shops for cleaning pipe ends, deburring fittings, and surface conditioning prior to bonding or coating.

Key Features

• 2-inch brush diameter for compact access in tight working areas
• Silicon carbide abrasive material - effective on non-ferrous metals, ceramics, and composites
• 180 grit for fine to medium surface conditioning and finishing
• Crimped fill configuration for consistent abrasive contact on uneven surfaces
• 1/4-inch shank mounts directly to die grinders, rotary tools, and standard drill chucks
• 5,000 RPM maximum speed rating

Compatibility

Designed for use with rotary tools, die grinders, and drills equipped with a standard 1/4-inch chuck or collet. Suitable as a replacement cup brush in any application requiring a 2-inch diameter, 1/4-inch shank, 180-grit silicon carbide crimped brush.

Installation Notes

Install the shank securely into the tool chuck or collet before operating. Do not exceed the 5,000 RPM maximum rated speed. Always wear appropriate eye protection and follow applicable ANSI safety standards for abrasive tools. Inspect the brush for damage or excessive wear before each use and replace if fill material is compromised.
