Frequently Asked Questions

What is the OSG 17437508 jobber length drill bit used for?

The OSG 17437508 is a 7/16" V-coated cobalt jobber-length drill bit with a 130° R-thinning point and coolant-through design. It is used for high-performance drilling in tough materials like stainless steel and hardened alloys, where coolant delivery extends tool life and improves chip evacuation.

What are the specifications of the OSG 17437508 drill bit?

The OSG 17437508 is a 7/16" (0.4375 inch) jobber-length drill bit with a 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 17437508 drill bit worldwide?

3G Electric supplies the OSG 17437508 V-coated cobalt coolant-through drill bit to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for a quote and lead time on this precision tool.

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

For hardened steel, choose a cobalt or carbide drill bit with coolant-through capability, like the OSG 17437508. The 130° R-thinning point reduces thrust and heat, while the V-coating provides wear resistance. Ensure your machine has a through-spindle coolant system for best results.
