What CCMT 060204 tells you on the shop floor
80° corner: strong yet versatile, turns and faces with the same insert.
Positive insert (7°): lower cutting forces and less chatter. For finishing, boring, thin-walled parts and lighter machines.
Pressed, medium tolerance: economical, fine for roughing and where you do not need repeatability to a few hundredths of a mm at every insert change.
Small radius: lower forces and chatter, good finish at low feed.
Typical holders for CCMT
For a positive rhombic 80° insert the most common ISO 5608 holders are:
- SCLCR/L · lead angle 95°
- SCACR/L · lead angle 90°
The final R or L means right or left hand. Shank size, length and the exact clamping are in the manufacturer's catalogue.
In inches, with the ANSI designation, the same insert is CCMT 21.51: size in eighths of an inch, thickness in sixteenths, radius in sixty-fourths. Converting any code, both ways, is in ISO Inserts Pro.
