Reading the code

What VCGT means

The first four letters of an ISO 1832 designation give the shape, the clearance angle, the tolerance class, and the hole and chipbreaker.

Code	Feature	Meaning
V	Shape	35° rhombic
C	Clearance angle	7° (positive insert)
G	Tolerance class	Class G
T	Hole and chipbreaker	Hole countersunk on one side, chipbreaker on one face

Where VCGT inserts are used

The 35° corner gives the most access for profiling and copying fine contours, but it is the weakest of the common corners, so it is used for light cuts and finishing.

VCGT is a positive (7° clearance) 35° rhombic turning insert. It has a countersunk hole for a clamping screw. The chipbreaker is on one face only. Positive inserts cut with lower forces, which suits finishing, small diameters, internal turning and less rigid setups. Tolerance class G is tighter than class M; inserts in this class are often ground, for more precise dimensions.

Choose the size for your depth of cut, the corner radius for the feed and finish, and a holder made for VCGT inserts of that size.

Dimensions shown are nominal values; a dash means the dimension has not been verified for this insert. Confirm the dimensions against the product drawing. The detailed chipbreaker geometry, grade and coating are not specified by the four-letter format; we confirm them with the quotation. Confirm the fit with the pocket and clamping system of your holder or cutter.
