Value Collection 22689 Ball Abrasive Bur 1/8 Inch Carbide

Product Description

The VALUE COLLECTION 22689 is a ball-shaped abrasive bur designed for precision grinding, deburring, and material removal in metalworking and fabrication applications. Built to industry specification SD-42, this bur features a solid carbide head with an uncoated finish, delivering consistent cutting performance on hardened materials. The 1/8 inch shank diameter fits standard die grinders, rotary tools, and flex-shaft handpieces commonly used by machinists, tool-and-die makers, and general fabricators. The ball head geometry allows access to contoured surfaces, interior cavities, and radiused profiles that flat or cylindrical burs cannot reach.

This bur is suited for bench-level deburring, port work, mold finishing, and surface blending tasks in machine shops, maintenance facilities, and production environments. The SD-42 specification indicates standardized geometry, making it a consistent choice for shops that spec burs by industry code. It is sold individually and is appropriate for both light production use and one-off repair work where a small-diameter ball bur is required.

Key Features

• Ball head geometry for contouring, cavity work, and radiused surface access
• Solid carbide construction for durability on hardened and abrasive materials
• Uncoated head finish suitable for general-purpose grinding and deburring
• SD-42 industry specification for standardized geometry and interchangeability
• 1/8 inch shank diameter compatible with common die grinders and rotary tools

Compatibility

Designed as a standard SD-42 ball abrasive bur for use with die grinders, rotary tools, and flex-shaft machines accepting a 1/8 inch collet or chuck.

Installation Notes

Installation is performed by machinists or fabricators using standard rotary tool or die grinder equipment. Ensure the tool is fully powered down and the collet is released before inserting or removing the bur. Secure the shank fully into the collet to the recommended engagement depth before operation. Always wear appropriate eye protection and follow shop safety protocols when operating rotary cutting tools.
