Milling Grades Uncoated Carbide Grades Features Due to KORLOY's advanced sintering technology, our uncoated carbide grades have a fine alloy structure which is necessary to get superior quality from a uncoated cutting tool P type Advantages Consist of P,M,K carbide grades and can be used in all kinds of workpiece Excellent quality at machining with coolant, due to the superior thermal crack resistance of the carbide Due to the special design of carbides, it has fine micro structure and low affinity with workpiece It has excellent toughness and produces lower cutting loads M type Selection system K type Workpiece Grade Recommended cutting speed(m/min) ISO Application range Steel A30 80 (60 100) P30 A30 Cast iron H01, H05 150 (110 190) K10 H01 H05 H10 H10, G10E 120 (90 150) K20 G10E Aluminum alloy H01 600 (450 750) N10 N Copper alloys H05 425 (320 530) N20 H05 Main composition and application range Workpiece Composition Features Workpiece P WC-TiC-TaC-Co Excellent thermal shock resistance and plastic deformation resistance Carbon steel, Alloy steel, Stainless steel M WC-TiC-TaC-Co General grades with thermal shock resistance and hardness Carbon steel, Alloy steel, Stainless steel, Cast steel K WC-Co High hardness and superior wear resistance Cast iron, Non-ferrous metal, Non metal The physical properties of grades Workpiece Grade Hardness (HRA) TRS (kgf / mm2) Young’s modulus (103kgf / mm2) Thermal expansion coefficient(10‘6 / 0C) Thermal conductivity (cal / cmsec0C) ST05E 92.7 140 - ST10P 92.1 175 48 6.2 25 ST20E 91.9 200 56 5.2 45 A30 91.3 230 53 5.2 - U10E 92.4 170 47 M U2 91.1 210 88 A30 91.3 230 53 5.2 - A40 89.2 270 - H2 93.2 185 61 4.4 105 K H01 92.9 210 66 4.7 109 G10E 90.9 250 63 - 105 1KPa = 102kgf/m2, 1w/mk = 2.39x10-3cal/cm-sec'°c Grades & Chip Breakers 26
