(Note 1) The above values are average condition values at actual cutting speeds. The values change slightly according to the state of a machine
to be used and method of workholding. Adjust the values depending on an actual machine condition, referring to the above values.
(Note 2) For end mills with a carbide shank, you will be able to set about 20 percent higher cutting conditions.
(Note 3) Please note the following when machining hardened steel with MP8010.
• Shorten tool overhang as much as possible.
• Use a carbide shank type.
• Depth of cut setting is important to prevent fracture.
