M.a. Ford. 69080020L3 Carbide Abrasive Bur Ball Nose Tree

Product Description

The M.A. FORD. 69080020L3 is a single-cut carbide abrasive bur with a ball nose tree head profile, designed for aggressive material removal and contour finishing in metalworking applications. The cutting head measures 0.125 inches in diameter with a 0.5 inch length of cut, and the overall tool length is 3 inches. The uncoated carbide head runs at up to 90,000 RPM, making it well suited for use in pneumatic die grinders and high-speed rotary tools. Machinists, tool-and-die technicians, and fabricators install this bur when precise shaping, deburring, or surface blending is required on hard or abrasive materials.

This bur is intended for use on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. The ball nose tree geometry allows access to contoured surfaces, internal radii, and recessed areas where flat or cylindrical profiles cannot reach. It is commonly used in mold and die finishing, weld preparation, port work, and general metal fabrication. The 1/8 inch shank fits standard die grinder collets and rotary tool chucks, making it a direct-use tool in most shop and field setups.

Installation Notes

Installation is performed by machinists, fabricators, or tool-and-die technicians using a die grinder or rotary tool with a 1/8 inch collet. Confirm the collet is clean and the shank is fully seated before tightening. Always verify the tool and spindle RPM rating before use and do not exceed the 90,000 RPM maximum. Eye protection and appropriate PPE are required when operating rotary burs on metal.
