Countersink EUC DIN 335C 90degree D.12,4mm HSS special 3-flute shank Z.3 BECK 30881874

HSS - specially coated - DIN 335 C - 3 cutting edges - countersink angle 90 ° - right-hand cutting - precision design - radially relief-ground - for machining steel, cast iron and non-ferrous metals - Advantages: - Reduction of axial force by 50 % (= less feed force) - Reduction of radial force by 25 % (= less chattering tendency) - Optimised countersinking thanks to new geometry, prepared cutting edges and the extremely unequal pitch (EUC) Other technical features: - Feed in steel up to 500 N: 0.12 mm/rev Advantages: - Reduction of axial force by 50 % (= less feed force) - Reduction of radial force by 25 % (= less tendency to chatter) - Optimised countersinking thanks to new geometry, prepared cutting edges and the extremely unequal pitch (EUC)
