Note 1) The values above are for average machining conditions. The optimum values can change slightly according to the condition and rigidity of the machine and work holding. Adjust the values accordingly. Note 2) For end mills with a carbide shank, up to 20% higher cutting conditions are possible. Note 3) Please note the following when machining hardened steel with MP8010.

  • Please shorten the overhang length as much as possible.
  • Use with carbide shank recommended.
  • Take special care with the depth of cut to prevent fracture.
