Frequently Asked Questions

What is the OSG 17781308 jobber length drill bit used for?

The OSG 17781308 is a 25/32" coolant-through cobalt drill bit with a 130° R-thinning point and V-coating. It is designed for high-performance drilling in tough materials like stainless steel and hardened alloys, where coolant delivery through the bit extends tool life and improves chip evacuation.

What are the specifications of the OSG 17781308 drill bit?

The OSG 17781308 is a jobber length drill bit with a 25/32" (0.7813 in) diameter, 130° R-thinning point, V-coated cobalt construction, and coolant-through capability. It is designed for demanding industrial drilling applications requiring precision and durability.

Where to buy the OSG 17781308 drill bit worldwide?

3G Electric supplies the OSG 17781308 V-coated cobalt coolant-through drill bit to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for a quote and lead time on this precision cutting tool.

How to select the right coolant-through drill bit for hardened steel?

For hardened steel, choose a coolant-through drill bit with cobalt construction and a specialized point geometry like the 130° R-thinning point on the OSG 17781308. The V-coating reduces friction and heat. Ensure your machine has through-spindle coolant capability to fully utilize the bit's design.
