Freely Specifiable Straight Blade End Mills Recommended Cutting Conditions

● This table was made based on an Rd (cut-in width) of 0.1 to 0.2 D and an Ad (flute width) of 2 mm.
● Use a machine and chuck that have rigidity and high accuracy.
● Select cutting oil suitable for the work material.
● Cutting conditions also change when the blade portion is shaped. So adjust the optimum cutting conditions by referring to the table below.
● For fraction sizes of flute diameter D, refer to the larger of the number values.
● Use Slim Shanks (SS-) at both feed speeds and rotational speeds 70% of the following conditions.
