What VCGT 160402 tells you on the shop floor

35° corner: reaches into grooves and complex profiles, but the edge is fragile. Light cuts only.

Positive insert (7°): lower cutting forces and less chatter. For finishing, boring, thin-walled parts and lighter machines.

Ground: a more precise edge, repeatable at every insert change. The choice for finishing and tight tolerances.

Small radius: lower forces and chatter, good finish at low feed.

Typical holders for VCGT

For a positive rhombic 35° insert the most common ISO 5608 holders are:

SVJCR/L · lead angle 93°
SVVCN · lead angle 72.5°

The final R or L means right or left hand. Shank size, length and the exact clamping are in the manufacturer's catalogue.
