Sgs Pro 12475 Carbide Ball Burr SD-2 5/16 in Single Cut

Product Description

The SGS PRO 12475 is a single-cut tungsten carbide ball burr conforming to the SD-2 industry specification. Designed for aggressive material removal and contour finishing, it features a 5/16-inch cutting diameter with a 1/4-inch length of cut and mounts via a standard 1/4-inch shank. The overall assembled length is 2 inches. The uncoated tungsten carbide head delivers the hardness and edge retention required for extended use on ferrous and non-ferrous metals. Rated to 45,000 RPM, this burr is suited for use in pneumatic die grinders and high-speed rotary tools common in fabrication, maintenance, and tool-and-die work.

This burr is used across metalworking, fabrication, and maintenance repair operations where precise material removal, port matching, or surface blending is required. The ball shape is particularly effective for internal radius blending, contour shaping, and cavity work. Compatible materials include steel, hardened steel, stainless steel, cast iron, titanium, cermet, nickel, copper, and copper alloys, making it a versatile option for machinists, pipefitters, and maintenance technicians working across multiple metal types.

Installation Notes

Install and remove this burr only with the rotary tool powered off and air supply disconnected. Secure the shank fully in the collet before operating and confirm the tool RPM rating meets or exceeds the 45,000 RPM maximum. Always wear appropriate eye protection and work gloves when operating carbide burrs at high speed. A licensed machinist or experienced tradesperson should perform any work requiring precise material removal tolerances.
