Frequently Asked Questions

What is the OSG 15218805 jobber length drill bit used for?

The OSG 15218805 is a general-purpose cobalt jobber-length drill bit used for drilling into hard materials such as stainless steel and alloy steels. Its 130° R-thinning point reduces thrust and improves chip evacuation, while the TiN coating extends tool life and allows higher cutting speeds.

What are the specifications of the OSG 15218805 drill bit?

The OSG 15218805 is a 7/32" (0.2188 inch) diameter jobber-length drill bit with a 130° R-thinning point and TiN-coated cobalt construction. It is designed for general-purpose drilling in ferrous metals and is manufactured by OSG under MPN 15218805.

Where to buy OSG 15218805 drill bits worldwide?

3G Electric supplies the OSG 15218805 drill bit worldwide. As a global industrial equipment distributor since 1990, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on this item.

How to select the correct OSG jobber length drill bit for stainless steel?

For stainless steel, select a cobalt jobber-length drill bit like the OSG 15218805 with a 130° point angle and TiN coating. The cobalt alloy provides heat resistance, and the coating reduces friction. Ensure the diameter matches your hole size and use appropriate cutting speeds and coolant.
