Harvey Tool 926512-C3 Carbide Sphere Bur 3/16 in

Product Description

The HARVEY TOOL 926512-C3 is a solid carbide sphere-profile abrasive bur with an AlTiN coating, designed for aggressive material removal in tight or contoured workpiece areas. The ball-shaped head measures 0.1875 inches in cutting diameter with a 0.16-inch length of cut, and the overall tool length is 2 inches. The double-cut tooth pattern produces a smoother finish than single-cut geometry while still clearing chips efficiently. This bur is sized on a 3/16-inch shank and is intended for use in pneumatic or electric die grinders operated by machinists, toolmakers, maintenance technicians, and fabricators working in production or job-shop environments.

This bur is suited for deburring, porting, shaping, and surface blending on ferrous and hard materials including cast iron, steel, and stainless steel. The sphere geometry allows the tool to reach concave surfaces, recesses, and complex contours that flat or cylindrical profiles cannot access. The AlTiN coating improves wear resistance and thermal stability at elevated cutting temperatures, extending tool life in abrasive materials.

Key Features

• Ball head geometry for contouring, blending, and recessed-area access
• Double-cut tooth style for efficient chip removal and smoother finish
• AlTiN coating for improved heat resistance and extended tool life in hard materials
• Solid carbide head construction for rigidity and wear resistance
• Rated for cast iron, steel, and stainless steel applications
• 3/16-inch shank fits standard die grinder and rotary tool collets

Compatibility

Designed for use in pneumatic or electric die grinders accepting a 3/16-inch collet. Suitable for material removal and finishing operations on cast iron, steel, and stainless steel workpieces per the SD industry specification designation.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician familiar with rotary cutting tools and die grinder safety practices. Ensure the grinder is powered off and the collet is fully released before inserting or removing the bur. Verify the collet size matches the 3/16-inch shank diameter and that the nut is properly tightened before operation. Always use appropriate eye protection and follow applicable OSHA and shop safety guidelines when operating rotary abrasive tools.
