Frequently Asked Questions

What is the OSG 10390605 screw machine drill bit used for?

The OSG 10390605 is a general-purpose cobalt screw-machine length drill bit used for high-speed drilling in production environments. Its 130° R-thinning point and TiN coating improve cutting efficiency and tool life on materials like steel and stainless steel. It is ideal for automated lathes and CNC machines requiring precise, short-hole drilling.

What are the specifications of the OSG 10390605 drill bit?

The OSG 10390605 is a 25/64" diameter screw-machine length drill bit with a 130° R-thinning point and TiN-coated cobalt construction. Its decimal equivalent is 0.3906 inches. The manufacturer part number is 10390605. This general-purpose bit is designed for high-speed drilling in ferrous metals and offers enhanced wear resistance.

Where to buy OSG 10390605 drill bits worldwide?

You can source the OSG 10390605 drill bit through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations.
