  • Item Features
  • Application
  • Standards
  • PM Plus™ high performance end mills deliver superior performance
  • 8% Cobalt substrate
  • High vanadium for high red hardness means exceptional toughness and high shock resistance
  • Run at higher feeds than conventional HSS or cobalt end mills
  • Provide excellent heat and wear resistance
  • Freer cutting minimizes heat build-up
  • Give excellent finish
  • Exceptional speeds in aluminum
  • Quiet, chatter free machining and high shear cutting
  • 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
  • Increase machining speeds to achieve optimum performance when using Cleveland coatings
  • Applicable on aluminum and non-ferrous materials
