• Max and min diameters are the values when nose radius .008 is used for insert TP08, and nose radius .016 for insert TC11 • During back boring, the rotation direction will be reversed • Inserts and insert holders are not included; must be ordered separately
The maximum allowable cutting speed Vc of the EWN BORING HEAD is 3,900 SFM, conditions differ according to the projection length of the holder and the rigidity of the machine. Set the spindle speed low and gradually increase until the optimum conditions are reached.
