SG-15M G1938 YG8 Carbide Preform – Semi-Finished for Custom Burr Production

The SG-15M G1938 is a semi-finished carbide preform made from YG8 tungsten carbide. YG8 contains 8% cobalt, providing good toughness and wear resistance — making it suitable for larger rotary burrs used in heavy material removal, weld cleaning, and industrial metalworking applications.

The preform is pre-shaped to the SG series flame/burin shape profile, which is ideal for aggressive cutting, contouring, and working in tight radii. The G1938 specification offers a larger dimensional starting point, helping to reduce roughing work and setup time for bigger burr sizes.

The standard 6mm shank is ready for final processing, including tooth grinding, coating, or other customizations based on your specific application. This preform is suitable for tool manufacturers, resharpening shops, or professional users who require high-quality blanks for producing larger custom rotary burrs.
