I make a holder for TNMG carbide inserts
I bought, cheaply when I got it, Kennametall's TNMG carbide inserts.
However, I didn't have a suitable blade holder for them, so now I'm going to make one.
In the end, making the holder was quite challenging even though its geometry is simple.
There will be strange angles and challenging setups for the workpieces.
In this video I use:
Weiler Matador SV (1972) Lathe
Schaublin SV-51 (1955) Milling machine
