TCMT 1102 inserts for general purpose machining of steel and stainless steel.
Nose radius is 0.4 mm.
These are the recommended feeds and speeds.
80-150 m/min cutting speed.
0.1 – 0.2 mm/rev feedrate

The TCMT style is one of the better types of inserts, because due to the sharper point angle they do not vibrate as much as something like a CCMT style insert.
