Product Description

OSG Helical-Flute Thread Mills for Stainless Steel & Super Alloys.

Frequently Asked Questions

What is the OSG Helical-Flute Thread Mill used for?

This OSG thread mill is designed for threading stainless steel and super alloys. Its helical-flute geometry reduces cutting forces and improves chip evacuation, making it ideal for producing 1/8"-27 NPT threads in tough materials. It is commonly used in aerospace, oil and gas, and general industrial machining applications.

What are the specifications of the OSG Thread Mill 4200000211?

The OSG thread mill has a 1/8"-27 NPT thread size, 3 flutes, and an EXO coated carbide construction. The manufacturer part number is 4200000211. It is specifically designed for threading stainless steel and super alloys, offering high wear resistance and thread accuracy.

Where to buy the OSG Thread Mill 4200000211 worldwide?
