Frequently Asked Questions

What is the OSG A Brand screw machine drill bit #3 used for?

This OSG A Brand drill bit is designed for drilling stainless steel and super alloys. Its WXL coating and 140° R-Thinning point reduce heat and improve chip evacuation, while coolant-through capability enables deeper, faster holes in tough materials.

What are the specifications of the OSG 520021312 drill bit?

The OSG 520021312 is a #3 screw-machine-length solid carbide drill bit with WXL coating, a 140° R-Thinning point, and coolant-through design. It has a 0.2130-inch diameter and is engineered for stainless steel and super alloys.
