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.
