Product Description

The OSG Extra Long Drill Bit (25/64") is a WXL-Coated Cobalt chip-clearing extended-length drill bit with a 300 mm overall length and a 120° X-thinning point. It is designed for deep-hole drilling applications requiring extended reach and durability.

Frequently Asked Questions

What is the OSG Extra Long Drill Bit 17523911 used for?

The OSG Extra Long Drill Bit 17523911 is used for drilling deep holes in tough materials like stainless steel and high-temperature alloys. Its 300 mm overall length and 120° X-thinning point reduce thrust and improve chip evacuation, making it ideal for industrial machining applications where standard-length bits cannot reach.

What are the specifications of the OSG Extra Long Drill Bit 17523911?

The OSG Extra Long Drill Bit 17523911 has a 25/64" (0.3906 inch) diameter, 300 mm overall length, 120° X-thinning point, and WXL-coated cobalt construction. The WXL coating enhances wear resistance and heat dissipation. The manufacturer part number is 17523911.

Where to buy the OSG Extra Long Drill Bit 17523911 worldwide?

You can source the OSG Extra Long Drill Bit 17523911 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 genuine OSG tooling to procurement teams and plant engineers internationally.

How to select the correct OSG extra long drill bit for deep hole drilling?

Select an OSG extra long drill bit based on hole depth, material hardness, and required finish. For depths exceeding 10x diameter, choose a bit with a 120° X-thinning point to reduce thrust and improve chip flow. The WXL-coated cobalt variant suits high-temperature alloys. Always match the diameter and overall length to your machine's capacity.
