Product Description

The M.A. FORD. 43375020 is a single-cut carbide abrasive bur with a ball head profile, conforming to industry specification SD-3. It is designed for material removal, deburring, shaping, and surface finishing in metalworking applications. The bur features an uncoated carbide head with a 3/8 inch cutting diameter and a 1/4 inch shank diameter, and is rated for operation up to 30,000 RPM. With an overall length of 2.3125 inches and a length of cut of 0.3125 inches, it is sized for use in die grinders and rotary tool setups. Installation and operation are handled by machinists, tool and die makers, and metal fabricators.

This bur is suited for aggressive material removal and fine finishing work on a wide range of metals, including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. The ball head shape makes it effective for contoured surface work, cavity blending, and internal radius finishing. It is commonly used in production machining, weld prep, mold and die finishing, and repair work where precise material removal in tight or curved geometries is required.
