| Thickness | 3.18 mm | 1/8" |
| Insert Width | 12.70 mm | 1/2" |
YBC301 Grade Material
YBC301 is a premium CVD (Chemical Vapor Deposition) coated grade. It features a thick Al2O3 layer and a TiCN coating over a high-strength carbide substrate. This "Black Diamond" technology provides superior heat resistance, making it the best wear-resistant milling insert for P15–P35 steel groups.
AFTN Geometry (Chipbreaker)
The AFTN geometry is optimized for general-purpose milling. It features a flat top with a precise rake angle that ensures stable chip flow and minimizes cutting force, which is essential for reducing spindle wear on your CNC machinery.
