What TCGT 110202 tells you on the shop floor

60° corner: general turning, three corners (six edges if double-sided negative); not as strong as C and W.

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.
