What VBMT 110308 tells you on the shop floor
35° corner: reaches into grooves and complex profiles, but the edge is fragile. Light cuts only.
Positive insert (5°): 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.
The most common radius: a balance between strength and finish.
Typical holders for VBMT
For a positive rhombic 35° insert the most common ISO 5608 holders are:
- SVJBR/L · lead angle 93°
- SVVBN · 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.
In inches, with the ANSI designation, the same insert is VBMT 222: size in eighths of an inch, thickness in sixteenths, radius in sixty-fourths. Converting any code, both ways, is in ISO Inserts Pro.

Designation to ISO 1832; reference tables: Mitsubishi Materials turning catalogue (insert identification). Holders to ISO 5608. Chipbreaker, grade and cutting data differ between manufacturers: the catalogue of the insert you use is what counts.
