ISO 16463:2014

Overview

ISO 16463:2014 - Polycristalline diamond inserts, tipped - Dimensions, types specifies the dimensional and designation requirements for indexable inserts tipped with polycrystalline diamond (DP). The standard applies to insert shapes defined in ISO 883 and ISO 6987 and defines the form, tolerances and designation conventions for tipped inserts used in turning and milling.

Key topics and technical requirements

• Scope and applicability: Covers inserts with shapes in accordance with ISO 883 and ISO 6987, tipped with polycrystalline diamond (DP).
• Insert shapes: Triangular (T), square (S), rhombic 80° (C), rhombic 55° (D), rhombic 35° (V) and trigon (W).
• Normal clearance (α): Standard normal clearances and their letter codes are defined (5° (B), 7° (C), 11° (P), 20° (E)).
• Cutting edge geometry: Specifies corner radii for turning inserts (rε = 0.2, 0.4, 0.8, 1.2, 1.6 mm) and allowance for milling inserts with wiper edges.
• Tolerance class and designation: Tolerance class follows ISO 1832; full designation format is based on ISO 1832 and includes cutting-edge condition, insert type and cutting-material symbol (e.g., DP05). Examples for turning and milling designations are provided.
• Detailed dimensions and tables: Comprehensive dimension tables and figures for each insert shape (T, S, C, D, V, W), both with and without fixing holes; includes cutting edge length l and related dimensional data.
• Materials and marking: References base material and cutting material classification in ISO 513; includes requirements for measurements and marking.
• Cross-reference: Annex A provides the relationship to ISO/TS 13399-2 component designations.

Practical applications and users

ISO 16463:2014 is used by professionals who design, manufacture, specify or inspect indexable cutting tools with polycrystalline diamond tips:

• Cutting tool manufacturers - ensuring consistent dimensions and interchangeability of DP-tipped inserts.
• Tooling and design engineers - choosing correct insert shape, clearance and radius for turning and milling toolholders.
• Procurement and quality assurance - verifying supplied inserts against standardized designations and tolerances.
• CNC programmers and workshop managers - selecting standardized tipped inserts for process planning and tool inventory.

Using this standard helps ensure compatibility between inserts and toolholders, consistent performance expectations, and clear product specification in purchasing and CAD/CAM tool libraries.
