Frequently Asked Questions

What is OSG Jobber Length Drill Bit #18 used for?

The OSG Jobber Length Drill Bit #18 is a general-purpose cobalt drill bit with a 130° R-thinning point and TiN coating, designed for drilling precise holes in hardened steels and tough alloys across machining, tooling, and maintenance applications.

What are the specifications of OSG Jobber Length Drill Bit #18?

This OSG drill bit has a #18 wire gauge size (0.1695 inch diameter), a 130° R-thinning point for reduced thrust, and a TiN-coated cobalt construction for heat resistance and extended tool life in industrial drilling operations.

Where to buy OSG Jobber Length Drill Bit #18 worldwide?

3G Electric supplies the OSG Jobber Length Drill Bit #18 (MPN 15169505) to global customers, handling full logistics, customs clearance, and delivery worldwide. Contact us for sourcing and lead time on this precision cutting tool.

How to select the right OSG jobber drill bit for hardened steel?

For hardened steel, choose a cobalt jobber drill bit like the OSG #18 with TiN coating and a 130° point angle. The R-thinning point reduces walking and cutting forces, while the cobalt substrate withstands high temperatures during deep-hole drilling.
