DC : Dia. Note 1) SMART MIRACLE coating has very low electrical conductivity; therefore, an external contact type of tool setter (electric transmitted) may not work. When measuring the tool length, please use an internal contact type (non-electricity type) or a laser tool setter. Note 2) When cutting titanium alloy, the use of water-soluble cutting fluid is effective. Note 3) 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 poor, vibration or abnormal sound can occur. In this case, please reduce the revolution and the feed rate proportionately, or set a lower depth of cut. Note 4) If the depth of cut is smaller, the revolution and the feed rate can be increased. Note 5) For slot milling, use a chuck with high clamping force. I179
