General grade we offered for round carbide cutters
Grade | Density(g/cm3) | Hardness(HRA) | TRS(N/mm2) (SampleB) | Recommended Applications |
YS2T | 14.45 | 91.5 | 2380 | An ultra fine cemented carbide with tungsten powder and binder cobalt. Good toughness and wear resistance. Suitable for low speed cutting allowing a big rake angle, Ensuring the sharpness of the edges, Bearing a heavy cutting force and Achieving good surface finish. |
YL10.2 | 14.45 | 91.5 1600 (HV3) | 2880 | With good transversal rupture strength and wear resistance. It is suitable for low speed rough turning and milling of heat resistant alloys ,titanium alloys and fiberglass. |
