ERP Cobalt Steel Square Nose End Mill, Uncoated (Bright) Finish, Roughing Cut, 35 Deg Helix, 3 Flutes, 2.4375" Overall Length, 0.2500" Cutting Diameter, 0.3750" Shank Diameter

Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys. Uncoated tools feature just the base substrate without any additional treatment or coatings and are suitable for a wide range of applications. Weldon shanks feature a round shank with one of more flats machined into the side for easy indexing and alignment. Due to the sinusoidal form on cutting edge, small chips are produced which allow faster feed rates then conventional end mills. A rough finish is produced which will require a finishing pass. Designed to machine soft materials such as aluminum, plastic, zinc alloys. Wide flutes provide rapid chip evacuation while high helix provides positive shearing action. For Aluminum Alloys.
