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
