Product Description

The YG-1 G8B59 X5070 Blue cutter is a 4 flute 0°Helix stub corner radius mill. Special high feed geometry delivers very high metal removal on prehardened and hardened steels. Nanograin carbide with silicone based coating supports dry machining to 1400°c and HRc70. Reduced clearance angles and short flutes increase strength for high speed roughing and finishing.

  • Use hydraulic, shrink, HP3/GSK, or power milling chucks
  • Heat resistance to 1400°
  • Strong negative land for high hardness machining
  • High abrasion resistance and mirror surface finish
  • Diameters 2mm–12mm
