Guhring tool materialsHigh speed steelsOnly high quality materials are used to produce GuhringHSS tools. Systematic selection of alloying elements ensurethe tool possesses the optimal characteristics for theindividual application.Tungsten, Molybdenum: increase tempering- and wearresistanceVanadium: increases wear-resistance of finishing toolsCobalt: enables increased hardening temperatures andimproves heat-resistance.GuhringdescriptionGermansteel descript.Material no.(steel code)Range ofapplicationcomparable steelsUSA France ItalyGreatBritainHSSHS 6-5-2(DMo5)1.3343standard tool material for mostcommon applicationsM 2Z 90 WDCV06-05-04-02HS 6-5-2 BM 2HSCOHSS-EHS 6-5-2-5(EMo5Co5)1.3243high heat-resistance, especially suitedfor roughing or when coolant insufficientM 35Z 90 WDKCV06-05-05-04-02HS 6-5-2-5 BM 35HSS-ES 6-5-3(EMo5V3)1.3344high friction resistance and cutting edge stability,especially important for reaming operationsM 3Z 120 WDCV06-05-04-03HS 6-5-3 –M42HSS-EHS 2-9-1-8 1.3247increased heat resistance and hardness,suitable for difficult-to-machine materialsM 42Z 110 DKCWV09-08-04-02-01HS 2-9-1-8 BM 42HSS-E-PM10-2-5-8PM52HS 6-5-3-8PM301.32531.3294high hardness, heat-resistance andcutting edge stability, very dense structure–Technical330
