DC Depth ofcut <1DC < Please refer to the list abovefor depth of cut. DC : Dia. Note 1) When slotting, reduce the revolutions by 50 - 70% and the feed rate by 40 - 60%. Note 2) For austenitic stainless steel, titanium and heat-resistant alloys, VFMHV is recommended. Note 3) The irregular helix flute end mill has a large 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. I I187
