SOLID END MILLS  1)	When slotting, reduce the revolutions by 50  70% and the feed rate by 40  60%.
                 2)	For austenitic stainless steels, titanium and heat-resistant alloys, the VFMHV is recommended.
                 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 workpiece installation is poor, vibration or abonrmal sound can occur. In this case, please reduce the revolution and feed
                    rate proportionately, or set a lower depth of cut.
