GWS Tool Group is a leading manufacturer of thread whirling inserts. Our precise geometries, advanced substate, and coatings, along with FAST delivery and service are what separates us from the rest. We offer multiple grades and designs for any threading application.

• CG139-515—Standard High Performance Grade for SST, Biodur, Cobalt Chrome
• CG138-521—Ultimate Performance ZOMBIE – Titanium, Cobalt-Chrome, Stainless

For high volume applications, where tool life is essential, the Zombie grade is a great benefit for our customers.  Our Zombie whirler name was coined by one of our own customers.  The Zombie outperformed other thread whirling inserts time and again, leading to the conclusion that “you just can’t kill the Zombie.”
