2699AZ, Type N, K10-20F, solid carbide, TiAlN coating, uneven angle of twist 35/38°, angle of cut 9°, cutting tolerance h10, weldon flat (HB), shank tolerance h6, long, unequal pitch, with corner radius, number of teeth 4, axial internal cooling, DIN 6527L Application General-purpose end mill for roughing and finishing with the same tool. Higher material removal rate due to optimised cutting geometry. Properties The uneven angle of twist reduces active vibrations. The flanging radius improves production reliability due to increased stability in the corner area.
