              Cut-Off on Eccentric Tubes
              Inserts with 4º lead angle are usually recommended
              for tubes. However, the combination of eccentric bore
              and machine resiliency may increase feed-snap on   ETG 3-4 (for 3 and 4 mm tools)
              breakthrough and damage the cutting edge. Changing
              to 6º lead angle inserts will moderate breakthrough.
              Alternatively, inserts with an extra negative rake-land that
              strengthens the cutting edge are available on request.
