Small D.O.C. ap = 0.1 ~ 0.3 mm

HL Hardened steel finishing

55HRC or less

HD Removing carburized layer Large D.O.C.

From carburized layer to unhardened layer ap = 0.3 ~ 0.7 mm

Advantages of MEGACOAT

Improved Stability

High speed

Extended tool life

machining

Long tool life and stable machining due to superior heat-resistance and hardness. Stability improvement through prevention of crater wear (oxidation, diffusional wear). High thermal stability and surface smoothness provide excellent surface finish.
