Sgs Pro 12728 Carbide Ball Bur SD-11 Double Cut 1/8 in

Product Description

The SGS PRO 12728 is a tungsten carbide abrasive bur in the SD-11 ball head configuration, designed for aggressive material removal and surface blending in metalworking and fabrication applications. The double-cut tooth style produces a fast, smooth cut with reduced chatter, making it well suited for deburring, contouring, and cavity work. The cutting head measures 1/8 inch in diameter with a 3/32 inch length of cut, and the bur runs on a 1/4 inch shank with a 2 inch overall length. Rated to 100,000 RPM, it is built for use in high-speed pneumatic or electric die grinders.

This bur is intended for professional metalworking, tooling, welding prep, and maintenance applications where precise stock removal is required. It is suitable for use on steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys. Typical users include machinists, fabricators, pipefitters, and maintenance technicians working in industrial, shop, and field environments. The uncoated tungsten carbide head delivers consistent cutting performance across this broad range of ferrous and non-ferrous materials.
