Harvey Tool 926516-C3 Carbide Bur Ball Double Cut 1/4 in

Product Description

The HARVEY TOOL 926516-C3 is a double-cut carbide abrasive bur with a ball-shaped head, designed for aggressive material removal in metalworking and fabrication applications. The head is manufactured from solid carbide and finished with an AlTiN coating to extend tool life under high heat and abrasive conditions. The cutting diameter measures 0.25 inches with a length of cut of 0.213 inches. The bur runs on a 1/4-inch shank and has an overall length of 2.5 inches. It is suited for use in die grinders and rotary tools operated by machinists, tool-and-die makers, and fabrication professionals.

This bur is built for use on cast iron, steel, and stainless steel. The ball head geometry and 270-degree included angle make it effective for contouring, deburring, porting, and blending in cavities and curved surfaces. It performs well in both hand-held die grinder setups and fixed rotary tool configurations. The double-cut tooth pattern removes material efficiently while producing a reasonably smooth finish, reducing the need for secondary finishing passes on hard ferrous metals.

Key Features

• Carbide head construction for durability in hard ferrous metal applications
• AlTiN coating improves heat resistance and extends tool life
• Double-cut tooth pattern for fast material removal with moderate surface finish
• Ball head shape with 270-degree included angle for contouring and cavity work
• 1/4-inch shank diameter compatible with standard die grinder collets
• Compact 0.25-inch cutting diameter suited for detail and precision work

Compatibility

Designed for use with standard 1/4-inch collet die grinders and rotary tools. Rated for cast iron, steel, and stainless steel material applications per manufacturer specification.

Installation Notes

Installation is performed by machinists or fabricators using a die grinder with a 1/4-inch collet. Ensure the grinder is fully powered off and the collet is fully disengaged before inserting or removing the bur. Inspect the shank and head for cracks or wear before each use and replace immediately if damage is found. Always wear appropriate eye and face protection when operating rotary abrasive tools.
