Niagara Cutter N33352 Cobalt Steel Square Nose End Mill, Weldon Shank, TiN Finish, Roughing/Finishing Cut, Non-Center, 30-Degree, 4-Flute, 3" OAL, 0.500" Cut Diameter, 0.500" Shank Diameter Truncated rougher-finisher removes material in less time than conventional end mills while producing a finer finish than fine- or coarse-pitch roughers Chipbreaker tooth design is suitable for machining mild and cold-rolled steels Titanium nitride (TiN) is a general-purpose coating that combines high-temperature resistance and increased hardness compared to uncoated end mills Cobalt steel resists abrasion and high cutting temperatures, and has higher feed rates than high-speed steel Square nose end mills (also called square end) create sharp, unrounded cuts
