End Mill Carbide HB12 VHM AT 440N 12mm 4-Flute AlTiN Coated

High-performance solid carbide end mill from the MILL HB12 series, designed for precision machining of hardened steels and high-alloy materials. The VHM (Vollhartmetall) construction ensures exceptional durability and cutting edge retention, while the AlTiN coating provides superior heat resistance and extended tool life.

Advantages

This end mill offers excellent wear resistance and thermal stability, enabling high-speed machining of materials up to 55 HRC. The 4-flute design with 35° helix angle ensures efficient chip evacuation and smooth cutting action, reducing vibration and improving surface finish. The cylindrical shank with h6 tolerance guarantees precise clamping and concentricity.

Suitable for

• Hardened steels (up to 55 HRC)
• Tool steels and high-alloy steels
• Roughing and finishing operations
• Milling of complex profiles and cavities
