All of our inserts and cutters are manufactured to our specifications using high grade carbide with micro-grain size of 0.7-1.0 µm. These micro-grains are combined with a 10% binder that yields a hardness of 1650 HV10. They are then finely ground to a razor cutting edge with toughness and durability for long-lasting, smooth cutting in the most dense hardwoods.
