Frequently Asked Questions

What is an OSG screw machine drill bit used for?

An OSG screw machine drill bit is designed for high-speed drilling in automated machining centers. Its short, rigid length reduces deflection, making it ideal for precise hole creation in production environments. The TiN coating extends tool life on ferrous metals.

What are the specifications of the OSG 10250005 drill bit?

The OSG 10250005 is a 1/4" general purpose cobalt screw-machine length drill bit with a 130° R-thinning point and TiN coating. It is designed for rigidity and wear resistance in production drilling. The manufacturer part number is 10250005.

Where to buy OSG drill bits worldwide?

3G Electric supplies OSG drill bits worldwide, handling full logistics and customs clearance. As a global industrial solutions provider, we source and deliver genuine OSG tooling to your facility. Contact us for pricing and lead time on the 10250005.

How to select the right screw machine drill bit?

Select a screw machine drill bit based on material, hole depth, and machine rigidity. For ferrous metals, a TiN-coated cobalt bit like the OSG 10250005 offers heat resistance. Match the point angle (130°) to the material hardness and ensure the shank fits your chuck.
