• This table is a guideline for selecting cutting parameters; adjust them as needed according to the machine and workpiece conditions • Internal high pressure coolant may cause deflection of the holder; lower the pressure when close tolerance is required • These conditions are determined when the boring bar is mounted on the BIG NEW Hi-POWER MILLING CHUCK or NEW BABY CHUCK
