Product Description

The OSG Extra Long Drill Bit (5/64") is a WXL-Coated Cobalt chip-clearing extended-length drill bit with an 85 mm overall length and a 120° X-Thinning Point. This OSG-manufactured tool (MPN 17515311) is designed for deep-hole drilling applications requiring extended reach and cobalt durability.

Frequently Asked Questions

What is the OSG Extra Long Drill Bit 17515311 used for?

The OSG Extra Long Drill Bit 17515311 is designed for drilling deep holes in hard materials such as stainless steel and alloy steels. Its 85 mm overall length and 120° X-thinning point reduce thrust and improve chip evacuation, making it ideal for industrial machining applications where standard bits cannot reach.

What are the specifications of the OSG Extra Long Drill Bit 17515311?

The OSG Extra Long Drill Bit 17515311 has a diameter of 5/64" (0.0781 inch), an overall length of 85 mm, and a 120° X-thinning point. It features a WXL-coated cobalt construction for heat resistance and extended tool life. The manufacturer part number is 17515311.

Where to buy the OSG Extra Long Drill Bit 17515311 worldwide?

You can source the OSG Extra Long Drill Bit 17515311 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply this WXL-coated cobalt drill bit to procurement teams globally.

How to select the correct OSG Extra Long Drill Bit for deep hole drilling?

Select the OSG Extra Long Drill Bit based on hole depth, material hardness, and required diameter. For hard materials like stainless steel, choose the WXL-coated cobalt variant (e.g., MPN 17515311) with a 120° X-thinning point to reduce cutting forces. Ensure the overall length (85 mm) exceeds the hole depth for proper chip clearance.
