Note: Cutting conditions in the above table show standard cutting conditions. Cutting conditions may change due to the rigidity and power of the machine and the workpiece material. Especially in case of making deep hole drilling (L/D is over 5), the lower cutting speed is better for longer tool life. The coolant pressure must be 0.5 MPa - 1MPa. Especially for small diameter drill, the higher pressure is recommended. Oil holes that become blocked may cause drill breakages. A fi lter to prevent the circulation of chips must be used on the coolant supply system.
