Product Description
X5070 Multi Flute 45° Helix Ex-Long End Mill (G8D64) is a 6&8-Flute Ball Nose for HRc45–70. It uses a nanograin carbide substrate with blue silicone based coating for dry machining to 1400°c. The long length 45° helix and strong negative land deliver feed rates, surface finish, and tool life. Suitable for steels, heat resistant steels, and hardened steels up to HRc70, including trochoidal machining.
