Overview
ISO 16462:2014 - "Cubic boron nitride inserts, tipped or solid - Dimensions, types" is an International Standard that defines the dimensions, shapes, types and designation rules for indexable inserts either tipped with cubic boron nitride (CBN) or made of solid CBN. This second edition (2014) replaces the 2004 edition and applies to insert shapes in accordance with ISO 883, ISO 3364, ISO 3365 and ISO 6987, and to cutting materials designated BL, BH, BC.
Key topics and requirements
- Scope and applicability: Covers tipped and solid CBN inserts for turning and milling with standardized shapes and dimensions.
- Insert shapes: Triangular (T), square (S), rhombic 80° (C), 55° (D) and 35° (V), round (R), and trigon (W).
- Clearance angles: Normal clearance αn options - 0° (N), 5° (B), 7° (C), 11° (P).
- Corner radii and edge features: Specified corner radii for turning (e.g., 0.2, 0.4, 0.8, 1.2, 1.6 mm) and options for wiper edges in milling; non-tipped corner designs are optional.
- Dimensions and tolerance classes: Detailed dimension tables (Tables 1–13) for inserts with and without fixing holes and for turning and milling application cases; tolerance class follows ISO 1832.
- Designation and marking: Designation format follows ISO 1832 conventions with examples for solid and tipped inserts (see clauses 4.2 and 4.3); marking and measurement requirements are specified.
- Normative references: Includes ISO 513 (cutting material classification), ISO 1832 (designation), ISO 883, ISO 3364, ISO 3365, ISO 6987 and others.
- Annex: Informative mapping to ISO/TS 13399-2 for digital/tooling data interoperability.
Practical applications and users
ISO 16462:2014 is intended for professionals involved in precision machining and tooling standardization:
- Tooling and insert manufacturers - to design and produce interchangeably sized CBN tipped and solid inserts.
- CNC machining and manufacturing engineers - to select correct insert geometries for hard-cutting applications (e.g., hardened steels, cast irons).
- Production planners and procurement - to ensure consistent specifications when sourcing CBN inserts.
- Quality, inspection and metrology teams - to verify dimensional conformity to ISO tables and tolerance classes.
- CAM programmers and tooling libraries - to use standardized insert designations and dimensions in tooling databases.
