(Tool life is short compared to wet cutting.) Note2) We recommend wet cutting with internal coolant for titanium alloy and heat resistant alloy. Note3) When clamp rigidity is low and tool overhang is long, we recommended to reduce the cutting speed and the feed rate by 30%. y Cutting Conditions with Wiper Insert (inch) Work Material Hardness MainInsertGrade WiperInsertGrade vc(SFM) fz(IPT) ap ae P VP15TF MP VP15TF WP 820 (655 ─ 985) .012 (.008 ─ .016) < .0197 < 0.8DC Mild Steel < 180HB MP6120 M MP6120 M 820 (655 ─ 985) .012 (.008 ─ .016) < .0197 < 0.8DC VP15TF MP VP15TF WP 720 (560 ─ 885) .012 (.008 ─ .016) < .0197 < 0.8DC Carbon Steel,Alloy Steel 180 ─ 280HB MP6120 M MP6120 M 720 (560 ─ 885) .012 (.008 ─ .016) < .0197 < 0.8DC VP15TF MP VP15TF WP 460 (330 ─ 590) .012 (.008 ─ .016) < .0197 < 0.8DC Carbon Steel,Alloy Steel 280 ─ 350HB MP6120 M MP6120 M 460 (330 ─ 590) .012 (.008 ─ .016) < .0197 < 0.8DC K Tensile MC5020 MK,HK MC5020 WK 1050 (820 ─ 1310) .012 (.008 ─ .016) < .0197 < 0.8DC Gray Cast Iron Strength < 350MPa VP15TF MP VP15TF WP 720 (490 ─ 985) .012 (.008 ─ .016) < .0197 < 0.8DC L Tensile MC5020 MK,HK MC5020 WK 820 (655 ─ 985) .008 (.004 ─ .012) < .0197 < 0.8DC Ductile Cast Ilon Strength < 450MPa VP15TF MP VP15TF WP 655 (490 ─ 820) .008 (.004 ─ .012) < .0197 < 0.8DC Tensile MC5020 MK,HK MC5020 WK 720 (655 ─ 820) .008 (.004 ─ .012) < .0197 < 0.8DC Ductile Cast Ilon Strength < 800MPa VP15TF MP VP15TF WP 560 (490 ─ 655) .008 (.004 ─ .012) < .0197 < 0.8DC S Heat Resistant Alloy ─ VP15TF MP VP15TF WP 130 (65 ─ 165) .006 (.004 ─ .008) < .0197 < 0.8DC H Hardened Steel 40 ─ 55HRC VP15TF MP VP15TF WP 260 (195 ─ 330) .006 (.004 ─ .008) < .0197 < 0.8DC Note 1) When clamp rigidity is low and tool overhang is long, we recommended to reduce the cutting speed and the feed rate by 30%.
