What DCGT 11T304 tells you on the shop floor
55° corner: gets into shoulders and follows profiles. For semi-finishing and finishing.
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 DCGT
For a positive rhombic 55° insert the most common ISO 5608 holders are:
- SDJCR/L · lead angle 93°
- SDNCN · lead angle 62.5°
The final R or L means right or left hand. Shank size, length and the exact clamping are in the manufacturer's catalogue.
