M.a. Ford. 70030020 Carbide Ball Bur SD-51 0.25in

Product Description

The M.A. FORD. 70030020 is a carbide abrasive bur in a ball head shape, conforming to SD-51 industry specification. It features a 0.25-inch cutting diameter and a single-cut tooth style that removes material efficiently while producing a smoother surface finish than double-cut alternatives. The overall length is 1.7188 inches with a 1/8-inch shank diameter, making it compatible with standard die grinders and rotary tools. This bur is suited for deburring, blending, and shaping operations performed by machinists, tool-and-die makers, fabricators, and maintenance technicians working in metalworking and manufacturing environments.

The 70030020 is designed for use on a broad range of materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Its ball profile is particularly well suited for contoured surface work, cavity blending, and internal radius finishing. The uncoated carbide head maintains consistent cutting performance across hard and abrasive workpiece materials. This is a single-piece package intended for bench-level or field repair applications where precision material removal is required.

Compatibility

Designed as an SD-51 specification ball-style carbide bur replacement suitable for 1/8-inch collet die grinders and rotary tools used in metalworking, fabrication, and maintenance applications.

Installation Notes

Installation and operation should be performed by qualified machinists or metalworking technicians familiar with rotary tool safety practices. Always power down and disconnect the die grinder before inserting or removing the bur from the collet. Ensure the shank is fully seated and the collet nut is properly tightened before operation. Do not exceed the rated maximum of 45,000 RPM, and always wear appropriate eye protection and gloves when operating abrasive rotary tools.
