Overview - ISO 3466:2016 (Machine taper pin reamers with parallel shanks)
ISO 3466:2016 specifies the dimensional requirements for machine taper pin reamers with parallel shanks. The standard covers only metric dimensions and defines tools intended to produce holes for taper pins manufactured to ISO 2339, covering nominal pin diameters from 2 mm to 12 mm. Unless otherwise stated, the reamers are right‑hand cutting; flute form may be straight or left‑hand spiral at the manufacturer's option.
Key topics and technical requirements
- Scope and intended use
- Reamers designed specifically to create holes for ISO 2339 taper pins (2 mm–12 mm).
- Applies only to reamers with parallel shanks (not Morse taper shanks).
- Dimensional data
- Detailed dimensional tables (Table 1) give cutting diameters, taper diameters, shank lengths, overall lengths and related tolerances.
- Driving tenon dimensions (when required) are specified by reference to ISO 4203.
- Cutting and geometry
- Default cutting direction: right‑hand cutting.
- Flutes: straight or left‑hand spiral permitted.
- Normative and informative links
- Normative reference: ISO 4203 (parallel shank tools - driving tenons and sockets).
- Annex A maps ISO 3466 designations to preferred symbols in ISO 13399 (tool data exchange).
- Related tool types
- Hand taper pin reamers: ISO 3465.
- Machine taper pin reamers with Morse taper shanks: ISO 3467.
Practical applications and users
Who uses ISO 3466:2016:
- Tool manufacturers designing and producing machine taper pin reamers to ensure interchangeability and conformity with metric dimensions.
- Production and assembly engineers specifying correct reamers for creating precise taper‑pin holes in mechanical assemblies.
- Quality and inspection teams verifying tool dimensions and hole tolerances against standardized values.
- Procurement and supply chain teams sourcing reamers and ensuring compliance with international standards.
- CAM/CAD and tooling data managers using the Annex A mapping to ISO 13399 for consistent tool data representation and exchange.
Practical benefits:
- Ensures compatibility between reamers and taper pins to ISO 2339.
- Simplifies sourcing and specification by using standardized metric dimensions.
- Facilitates digital tool data exchange and automation through ISO 13399 alignment.
