Nanograin Carbide
Manufactured with the hardest nanograin carbide sub-strate and coated with YG-1’s silicon based X5070 blue coating. This special coating and substrate combination is heat resistant up to 1,400°C, enabling extreme cutting speeds in the hardest of steels up to 70 Rockwell.
Dry Cutting
Designed for DRY machining. Tool life can actually be increased by up to 2.5 times when machining dry compared to with coolant. Flood coolant can cause thermal shock cracks in the coating and break down the cutting edge in high temperatures. Dry machining can also maintain a sharper cutting edge for longer.
