Frequently Asked Questions

What is the OSG A Brand screw machine drill bit used for?

This OSG A Brand drill bit is designed for precision drilling in stainless steel and super alloys. Its WXL-coated carbide construction and 140° R-thinning point provide efficient chip evacuation and heat resistance, making it ideal for high-strength materials in aerospace, automotive, and medical manufacturing.

What are the specifications of the OSG 8665850 drill bit?

The OSG 8665850 is a coolant-through solid carbide screw-machine length drill bit with an 8.5 mm diameter, WXL coating, and a 140° R-thinning point. It is engineered for stainless steel and super alloys, with a part number of 8665850 and a decimal equivalent of 0.3347 inches.

Where to buy OSG drill bits worldwide?

3G Electric supplies OSG drill bits worldwide, handling full logistics and customs clearance for global delivery. As a sourcing partner, we provide genuine OSG A Brand tooling like the 8665850 model, ensuring you receive the correct specifications for your industrial applications.

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

Select an OSG drill bit with WXL coating and coolant-through capability for stainless steel and super alloys. The 140° R-thinning point reduces thrust and improves chip flow. Match the diameter (e.g., 8.5 mm) to your hole size and ensure your machine supports through-coolant for optimal performance.
