Cleveland C42861 1/2 557RH 4F Cleveland End Mill Center Cutting General Purpose Single End Square End Series: HGC-4C 1/2 in Diameter Cutter 4 in Overall Length 2 in Length of Cut 4 Flutes Spiral Flute 1/2 in Shank Diameter Right Hand Cutting Direction 30 deg Helix Angle Straight/Weldon Flat Shank Cobalt 8/M42 HSS TiN Coated Characteristics and Features High red hardness for high heat conditions Multi-flute end mills deliver a smoother finish and are better for peripheral cuts Multi-flute end mills have a heavy duty cross section for better rigidity Increased number of flutes mean more cutting edges, providing more cutting action Coatings reduce heat and abrasion to increase tool life The increased lubricity of the coating surface reduces material adhesion and built-up edge, enabling even higher feed rates Coatings reduce the amount of torque required for machining to allow more efficient use of equipment TiN (titanium nitride) coating in gold color intended for aggressive machining TiN coating increase machining speed 25 to 30% versus bright speeds Applicable on titanium alloys, nickel alloys, cobalt alloys and stainless stee
