Frequently Asked Questions

What is the OSG Jobber Length Drill Bit 15257005 used for?

The OSG 15257005 is a general-purpose cobalt jobber-length drill bit with a 130° R-thinning point and TiN coating. It is designed for drilling into hard materials like stainless steel and alloy steels in industrial machining, metalworking, and maintenance applications.

What are the specifications of the OSG 15257005 drill bit?

The OSG 15257005 is a Letter F jobber-length drill bit with a 0.2570-inch diameter, 130° R-thinning point, and TiN-coated cobalt construction. It is designed for general-purpose drilling in tough materials, offering heat resistance and extended tool life.

Where to buy the OSG 15257005 drill bit worldwide?

How to select the right OSG jobber-length drill bit for my application?

Select based on material hardness and hole depth. The OSG 15257005 with TiN coating suits stainless and alloy steels. For softer materials, uncoated HSS may suffice. Match the Letter F (0.2570 inch) diameter to your hole size and use proper speeds/feeds for cobalt bits.
