Equilateral indexable inserts
For equilateral-equiangular- and equliateral-unequiangular indexable
inserts, the dimension of the side lenght in mm is given as
characteristic number. Figures behind the decimal point
are not taken into account, e.g. for the side lenght I=16.5mm.
(characteristic number 16)
TPGN 160301
When a single-digit characteristic number accours for designation
of the insert size, an 0 is put in front of it, e.g. for
side lenght I=9.525mm. (characteristic number 09)

Round indexable inserts
For round indexable inserts the diameter in mm is given as the
characteristic number. |
Unequilateral indexable inserts
Unequilateral-equiangular and unequilateral-unequiangular inserts,
the main cutting edge i.e. the longer cutting edge, is always
given as characteristic number. With these inserts the
fourth symbol is always an
' x '. |

The thickness of the insert in mm. is given as characteristic number.
Figures behind the decimal point are not taken into account.
When the characteristic number is a single digit, then
a 0 is put in front of it. e.g. with thickness s=3.18mm. (characteristic number
03)

With corner rounding:
As characteristic number for tips with rounded corners radius
is given in 1/10 mm. When there is a single digit characteristic
number, an 0 (zero) is put in front of it. e.g. rc=0.4
ise (characteristic number 04)
