Thanks! 1"x 6.50" 5 Flute Cobalt Roughing Square End Mill This listing is for 1 (one) 1"x 6.50" End Mill Description: 1' Dia. L:5.441 M42 8%COBALT 05/13 Type: flat end Number of flutes: 5 Material: Cobalt Shank diameter: 1" Cutter diameter: 1" Overall length: 6.5" Cobalt (M-42: 8% Cobalt): Provides better wear resistance, higher hot hardness and toughness than high speed steel. There is very little chipping or microchipping under severe cutting conditions allowing the tool to run 10% faster than HSS, resulting in excellent metal removal rates as well as good finishes. This material, combined with the proper geometry has proven the most cost-effective for machining cast iron, heat treated steels and titanium alloys. Coarse Tooth: This is the most commonly found profile. It is excellent in deep slotting conditions and heavy side cuts, and its design draws the least amount of power consumption. It is recommended for heavy machining conditions where high metal removal rates are required. Five Flute: Ideal for peripheral and finish milling. The additional flutes allow faster feed rates, but due to the reduced flute space, chip removal may be a problem. Produces a much finer finish than two and three flute tools.
