ISO 3364:2017 pdf download.Indexable hardmetal (carbide) inserts with rounded corners, with cylindrical fixing hole — Dimensions
1 Scope
This document specifies the dimensions of indexable hardmetal (carbide) inserts with rounded corners,with cylindrical fixing hole and with 0° normal clearance. These inserts are primarily intended to be mounted by top and hole clamping or by hole alone on turning and boring tools.

4 Types of insert
The types of indexable hardmetal (carbide) insert specified in this document are the following:
— TN: triangular inserts, with 0° normal clearance;
— SN: square inserts, with 0° normal clearance;
— CN: rhombic inserts, with 0° normal clearance and 80° included angle;
— DN: rhombic inserts, with 0° normal clearance and 55° included angle;
— WN: hexagonal (trigon) inserts, with 0° normal clearance and 80° included angle.
— VN: rhombic inserts, with 0° normal clearance and 35° included angle.
Inserts covered by this document are standardized with chip breakers on both faces, with chip breakers on one face only and with no chip breakers at all.
At present, neither the shape nor the dimensions of chip breakers are standardized. Thus, if necessary, special features have to be explained by means of a diagram or additional specifications.
Table B.1 gives the range of sizes for these inserts.
5 Interchangeability
5.1 Tolerances
Indexable hard metal (carbide) inserts specified in this document are provided in tolerance classes in accordance with ISO 1832. Other tolerances are given either in Table 1 for hole dimensions or in Tables 2 to 8 for insert dimensions.
5.2 Thickness, s, of inserts with chip breakers
The thickness, s, of inserts with chip breakers is defined as the distance between the cutting edge of the corner and the opposing supporting surface of the insert; see Figure 1 a) and b) for inserts with chip breakers on one face only and Figure 1 c) for inserts with chip breakers on both faces.
