NTK RNG43 0.05 SX5 ceramic lathe turning inserts SX5RNGN430-TNB

Description

Ten (10) used ceramic inserts.  They all have a very small chip here or there in the cutting edge.
The top two in the 3rd and 4th photos have a chamfer on the cutting edge on both sides.  I don't know if those have been modified or are a different type of insert.
At least the eight regular ones
should have lots of life left in them on the good portions of the cutting edge.
