RE : Radius Note 1) SMART MIRACLE coating has reduced electric conductivity; therefore an external contact type (electric transmitted) tool setter may not work. When measuring the tool length, please use an internal contact type (non-electricity type) tool setter or a laser type tool setter. Note 2) When cutting austenitic stainless steel, the use of water-soluble cutting fluid is especially effective. Note 3) If the depth of cut is smaller than this table, feed rate can be increased. Note 4) The irregular helix flute end mill has a larger effect on controlling vibration when compared to standard end mills. However, if the rigidity of the machine or the work material installation is very low, then vibration can occur. In this case, please reduce the revolution and feed rate proportionately, or set a lower depth of cut. Note 5) % is the inclination of the machined surface. End mill RE
