HGT Technology Co. introduces square end mills designed for reliable roughing and finishing in pre-hardened steels around HRC 55. Built for dimensional accuracy and edge life, this series suits toolrooms and production lines needing dependable steel performance without constant tool changes.
Engineered for HRC ~55 steels, these carbide tools pair proven square-end geometry with TiAlN coating for heat resistance and wear control. Choose 2-flute when chip space matters in slots and deep features; choose 4-flute for higher feed potential and added stability on profile and shoulder work. Consistent edge prep supports predictable surface finish and reduced deburr. Inch and metric sizes available.

Highlights
• TiAlN-coated carbide for wear/heat resistance in HRC ~55 steels
• 2F for chip evacuation; 4F for productivity and stability
• Square-end geometry for flats, shoulders, and accurate edges
• Suited to roughing-to-finish paths on pre-hardened steels
• Inch & metric; standard and extended lengths

For manufacturers targeting consistent steel throughput near HRC 55, HGT’s square end mills deliver the balance of finish, tool life, and predictable handling demanded in mold bases, fixtures, and general machining.
