Frequently Asked Questions

What is an OSG helical-flute thread mill used for?

An OSG helical-flute thread mill is used for cutting internal or external threads in stainless steel and super alloys. Its helical flute design reduces cutting forces and improves chip evacuation, making it ideal for tough materials in aerospace, automotive, and oil-and-gas applications.

What are the specifications of the OSG thread mill MPN 3900075?

The OSG thread mill MPN 3900075 has an M20x2.5 metric thread size, 4 flutes, and an EXO coated carbide body. The helical-flute geometry is engineered for stainless steel and super alloys. 3G Electric supplies this genuine OSG tool and can confirm full specs on request.
