HGT Technology Co. introduces corner radius end mills designed for reliable steel machining around HRC 55. The added corner radius strengthens the edge to reduce chipping and extend tool life on shoulders, pockets, and contour paths.
Engineered for HRC ~55 pre-hardened steels, these carbide tools combine proven square-profile cutting with a protective radius and durable TiAlN coating for heat and wear resistance. Use 2-flute for chip space in slots and deep features; choose 4-flute for higher feed potential and stable wall finishes. Available in inch and metric sizes.

Highlights
• TiAlN-coated carbide for wear/heat resistance in HRC ~55 steels
• Corner radius to resist edge chipping and extend tool life
• 2F for chip evacuation; 4F for productivity and stability
• Crisp floor/shoulder quality for pockets and profiles
• Inch & metric; standard and extended lengths

For shops targeting steady throughput in pre-hardened steels, this series balances durability and finish while cutting down on edge breakage and rework.
