Outside Turning holder for grooving using a Nero Diamond tip (V shape). 

Use V-shaped carbide inserts (35° diamond) for tight-corner turning, profiling, and small grooves, especially for precision finishing, as their narrow angle provides accessibility, but be aware they are more fragile than stronger shapes like squares or C-inserts, requiring lighter cuts and stable setups to manage vibration and avoid breakage. 

All holders already come with 1 carbide tip, screw and key for turning right away.
