Frequently Asked Questions

What is the OSG Jobber Length Drill Bit 15656205 used for?

This OSG general-purpose cobalt jobber-length drill bit is designed for drilling into hard materials such as stainless steel and alloy steels. Its 130° R-thinning point and TiN coating reduce heat and wear, making it suitable for production and maintenance drilling in industrial metalworking applications.

What are the specifications of the OSG 15656205 drill bit?

The OSG 15656205 is a jobber-length drill bit with a 21/32" diameter (0.6563 inches). It features a 130° R-thinning point and a titanium nitride (TiN) coating on cobalt high-speed steel. This combination provides hardness, heat resistance, and extended tool life for drilling ferrous metals.

Where to buy OSG drill bits worldwide?

3G Electric supplies OSG drill bits like the 15656205 to customers worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for pricing and lead time on this item.

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

For stainless steel, choose a cobalt jobber drill bit with a 130° point angle and a TiN coating, like the OSG 15656205. The cobalt alloy provides heat resistance, while the coating reduces friction. Ensure the bit diameter matches your hole size and that your drill speed is appropriate for the material hardness.
