438F81 Keyway End Mills

Bulk orders will be discounted, please contact us.

These keyway end mills feature a TiN coating that helps protect them from wear, increases chip flow in softer materials, and allows the end mills to run at higher speeds than keyway end mills with a bright finish. High-speed steel end mills provide good wear resistance for general purpose milling applications. High-speed steel end mills have some flexibility and can absorb some shock and vibration in machining tasks.
