Since my lathe is old and worn carbide tends to chip easily on it. Today I found a used parting holder and some Teledyne MP91M carbide inserts that I'd like to learn about. The damaged label appears to show MP91M and T?B?TN-21?4 and the inserts are inked MP91M, the holder has no markings and may not even be right for them, they seem to fit snugly without bottoming in the slot.

 Weird.  The only MP91M I found look a lot like the TDEX or SEHT used mostly in face mills.
 Oh, I also found one that looks like its for a shoulder mill.
 

Oh, here is one that's a parting insert.  Looks like its from Stellram. Now to just figure out if they make the size you need.
