Threading tools

The ingenious locking interface

iLock™ is a secure locking interface between the insert and tool holder that prevents the cutting forces from affecting the tool position. This results in high dimensional accuracy, long tool life, and good chip control.

Threading inserts and grades

Threads created by thread milling, thread turning, tapping or thread whirling must meet and exceed the rigorous standards and tolerances set by the oil and gas, automotive, medical and aerospace industries. Find the insert and/or grade here for achieving high quality thread profiles with excellent chip control and surface finish.
