Overview
ISO 4206:2016 defines the dimensional parameters and tolerances (in millimetres) for counterbores with parallel shanks and solid pilots intended for general use. This International Standard provides a consistent basis for manufacturers, designers and procurement specialists to specify counterbores that meet accepted tolerances and are compatible with common toolholder and piloting practices. The document includes a diagrammatic figure (Figure 1) and a tabulated set of dimensions and tolerances (Table 1); Figure 1 illustrates a counterbore with a cutting diameter greater than 5 mm.
Key Topics
- Scope and purpose: standardizes dimensions and limit deviations for counterbores with parallel shanks and solid pilots.
- Dimensions in millimetres: the standard specifies key dimensions such as cutting diameter, pilot diameter and shank diameter and associates each with tolerance classes.
- Diagrammatic guidance: Figure 1 is provided for orientation (not to convey construction details).
- Tabulated values: Table 1 lists dimension ranges and associated tolerances for ordering and manufacturing.
- Designation mapping: Annex A (informative) provides the relationship between ISO 4206 designations and preferred symbols in the ISO 13399 cutting-tool data representation scheme.
- Reference to ISO 286-2: tolerance classes and limit deviations reference the ISO 286-2 code system for linear sizes.
Practical keywords: counterbores, parallel shanks, solid pilots, dimensions, tolerances, ISO 4206:2016, interchangeability, tooling, CNC compatibility.
Applications
ISO 4206:2016 is directly applicable where controlled fit, repeatable assembly and tool interchangeability are required. Typical applications include:
- Production and procurement of hand and machine counterbores for secondary machining operations.
- Specification of tooling for CNC machining centers where consistent pilot and shank dimensions support accurate location and repeatable cycles.
- Sourcing and quality control of interchangeable cutting tools across suppliers and workshops.
- Integration with tooling databases and CAM/CNC systems when combined with ISO 13399 designations (Annex A).
Benefits:
- Interchangeability across manufacturers and toolholders.
- Consistent quality control through standardized tolerances.
- Improved CAD/CAM interoperability by mapping to ISO 13399 symbols.
Related Standards
- ISO 286-2 - Geometrical product specifications (tolerance classes for holes and shafts), referenced for tolerance class definitions.
- ISO 13399 - Cutting tool data representation and exchange; Annex A of ISO 4206 links designations to ISO 13399 symbols.
- ISO 4205 - Countersinks with parallel shanks and solid pilots (related tooling family).
Use ISO 4206:2016 when specifying or manufacturing counterbores to ensure dimensional conformity, reliable piloting and compatibility with industry tooling systems.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
