■ End mill, Long cut length, 2 flute 1) Please use VCLD for workpiece of 45HRC. 2) Vibration is liable to occur in the initial stages of machining, but after machining 1 -2m the machining becomes stable and vibration could disappear. 3) Side milling with large depth of cuts with end mills less than & 3 is not recommended. When side milling, divide the cutting depth into several times paths. 4) If chattering occurs, reduce the revolution and the feed rate proportionately and also reduce the depth of cut. 5) When drilling, please lower the feed rate by 70%.
