Two new variations of Iscar’s Cut-Grip inserts feature flat-top rakes without chipbreakers for threading. Precision ground for a 60-degree (MT) thread profile, the inserts are designed for machining threads on short chipping materials such as brass and cast iron.

The inserts can be installed in existing toolholders without modification.
