Features

  • Roughing end mills have chip-breaking cutting edges that remove material in less time than conventional end mills
  • Number of flutes varies, fewer flutes have more chip-carrying capacity and more flutes produce a finer finish
  • Uncoated (bright) tools have no additional surface treatment or coating for use on a broad range of materials
  • Cobalt steel resists abrasion and high cutting temperatures and has higher feed rates than high-speed steel
  • Square nose end mills create sharp, unrounded cuts
  • For use with aluminum/aluminum alloys, cast iron, nickel/nickel alloys, plastics, steel/steel alloys, titanium/titanium alloys
