NTK Micro-Grain Carbide is characterized by an extremely small grain size (less than 1μm).
This achieves high toughness with a perfect hardness at the same time. This effects extremely sharp cutting edges.
Compared to the conventional “Fine-Grain Carbide”, it offers excellent wear and tear resistance at high temperatures. NTK Micro-Grain Carbide with PVD coatings provides more resistance against wear.
