VK110super high wear-resistant

Ultra micro-grain quality carbide is ultra high wear resistant, but less impact-resistance. It is applied in mid and low speed light cutting of various materials that require ultra high wear resistance. Generally, it is applied in good work condition, stable cutting, good part fixture and continuous light-duty machining. Reference ISO K10

VK100super high hardness

General quenching for heat treatment of high hardness materials (HRC48° ~ 67°) and various types of quenching difficult material processing(including Ni, Cr, Mo, Si, Ti etc.),and SKD11,SKD61(processing HRC62°)HSS,SKH51,SKH57(processing 65°).

VP350:(high wear-resistant)

It is applicable for HRC18°~48°the material that like high temperature alloy\heat-resistant alloy\cast iron of nickel-vanadium-titanium alloy\stainless steel (including Ni, Cr, Mo, Si, Ti etc.) It is excellent machining tool before heat treatment and after thermal refining.
