GTZ Series End Mills have free cutting positive geometry which is ideally suited for aerospace alloys. These cutters have round high clearance angle round inserts that provide a smooth and clean cutting action. The combination of geometry and insert give the GTZ style tooling the machining qualities similar to helical tools. GTZ Series has precision hardware components to ensure quick accurate insert indexing. The hardened hardware components provide body protection for superior tool durability.
