Product Description
X-POWER PRO 4 Flute 30° Helix Long Corner Radius End Mill GM819 balances reach and reliability. Advanced ‘Z Coating’ with an ultrafine micrograin carbide substrate supports long life in wet or dry cutting. It machines steels, stainless steel, cast iron, and hardened steels to 55 Rockwell with accuracy. Compared to the original X-Power, expect 20–30% longer life and over 20% faster cutting. Corner radius edges enhance durability and surface finish during high speed, high precision milling.
