TCMT 1102 Inserts for machining Aluminium and plastics.
these are highly polished and sharp to help machine non ferrous materials.
starting cutting condition parameters:
Feedrate 0.10-0.20 mm/rev
Vc 100-160 mm/min
Ap (depth of cut) .1-2 mm
with cutting conditions somewhere in there you should get nice chip breaking and tool life.
We normally use 1 mm depth of cut and 0.15 mm/rev feedrate when using a .4 mm radius insert.
