Overview
ISO 6462:2011 - Face and shoulder milling cutters with indexable inserts - Dimensions specifies the standardized external and mounting dimensions for face and shoulder milling cutters that use indexable inserts. It defines cutter diameters, mounting interfaces, tolerances and dimensional tables to ensure interchangeability, safe handling and consistent designation of cutters used in milling operations. The standard covers common cutter sizes (from about 40 mm up to 500 mm) and three mounting styles.
Key topics and requirements
- Mounting styles:
- Style A - tenon drive with hexagon socket head cap screw.
- Style B - tenon drive with cutter retaining screw (interchangeability per ISO 2780).
- Style C - mounted on centring arbor with a 7/24 taper (interchangeability per ISO 2940-1).
- Cutting edge angles: standardized nominal insert edge angles of 45°, 60°, 75° and 90° (other angles permitted if compatible with ISO 11529-2 designation).
- Dimensional tables: specified values for cutting diameter (d), body diameter, functional length (LF), bolt circle, access holes, keyway dimensions and related tolerances for typical diameters (40–500 mm).
- Lifting holes: optional threaded lifting holes for cutters with d ≥ 250 mm (M12×27 for 250/315 mm; M16×34 for 400/500 mm) - manufacturer discretion but minimum sizes given.
- Material requirement: cutter body material shall have a minimum tensile strength of 700 N/mm².
- Designation and data mapping: uses ISO 11529-2 for designation and aligns abbreviated dimension terms with ISO/TS 13399-3, -4 and -50 for cutting tool data representation and exchange.
- Normative references: includes ISO 240, ISO 2780, ISO 2940-1, ISO 3365 and ISO 11529-2 as indispensable for application.
Applications - who uses ISO 6462:2011
- Tool manufacturers - design and produce face/shoulder milling cutters with standardized mounting and interchangeability.
- Machine tool and arbor designers - ensure compatibility with cutter mounting systems (tenon drives, taper arbors).
- CNC programmers and production engineers - select correct cutter geometry, diameter and mounting style for machining operations.
- Purchasing and quality control - verify supplier parts against standardized dimensions and tolerances.
- CAD/CAM and tooling data managers - map cutter properties into tool libraries using ISO/TS 13399 data dictionaries for digital exchange.
