Its 35\u00b0 helix and open two-flute geometry provide chip space and reduced cutting resistance for slotting, side milling, shoulder milling, pocketing and profiling. Standard cutting diameters from \u00d81 to \u00d820 mm are available with coated and selected uncoated configurations.<\/p>\n<div style=\"display: flex; flex-wrap: wrap; width: 100%; margin: 20px 0 0;
