Lead angle 0°/ 2° MSR / MSR-BT50 Recommended cutting conditions fz (mm/t) Recommended insert grades (Cutting speed Vc: m/min) Workpiece material Low cutting force General purpose MEGACOAT NB3P+NB4P NB3+NB4 PR1230 PR1210 Carbon steel 0.15 0.2 ★100~150~200 - Cast iron 0.15 0.2 - ★100~150~200 Stainless steel Not recommended Aluminum/Copper Not recommended * For MSR, cutting speed should be carefully adjusted depending on the length of toolholder protruding from the end of machine spindle. ★: 1st Recommendation • When the overhang length of toolholder is small, ➮ set the cutting speed to slightly higher than the recommended cutting conditions. ✩: 2nd Recommendation • When the overhang length of toolholder is long, ➮ set the cutting speed to slightly lower than the recommended cutting conditions.
