The OSG 10328105 is a general-purpose cobalt screw-machine length drill bit designed for high-speed drilling in tough materials. Its 130° R-thinning point reduces thrust and improves chip evacuation, making it ideal for automated machining centers and production environments requiring precise, repeatable holes.

The OSG 10328105 is a 21/64" (0.3281 inch) diameter screw-machine length drill bit with a 130° R-thinning point. It features a TiN-coated cobalt construction for enhanced wear resistance and heat dissipation. The manufacturer part number is 10328105, and it is classified as a general-purpose cobalt screw-machine length drill bit.

Select the OSG 10328105 for drilling holes in hardened steels or abrasive materials where a 130° point angle reduces walking and thrust. Match the 21/64" diameter to your hole size and ensure your machine spindle can accommodate screw-machine length shanks. For softer materials, consider a standard jobber-length bit instead.
