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
breakthrough and damage the cutting edge. Changing ETG 2 (for .079” tools)
to 6º lead angle inserts will moderate breakthrough. ETG 5-7 (for .197-.276” tools)
Alternatively, inserts with an extra negative rake-land that
strengthens the cutting edge are available on request.
