Frequently Asked Questions

What is an OSG #28 screw machine drill bit used for?

The OSG #28 screw machine drill bit is designed for high-speed drilling in production environments. Its 130° R-thinning point reduces thrust, while the TiN-coated cobalt construction handles harder materials like stainless steel and alloy steels. 3G Electric supplies this bit for precision machining across industrial sectors.

What are the specifications of the OSG 10140505 drill bit?

The OSG 10140505 is a #28 screw machine length drill bit with a 0.1405 inch diameter. It features a 130° R-thinning point and TiN-coated cobalt for heat resistance and wear life. This general-purpose bit is suited for automated machining operations. 3G Electric sources this genuine OSG tool for global delivery.

Where to buy OSG 10140505 drill bits worldwide?
