ISO 3467:2016 PDF

Overview

ISO 3467:2016 specifies the metric dimensions for machine taper pin reamers with Morse taper shanks. It defines the form and key sizes for reamers intended to produce holes for taper pins manufactured to ISO 2339, covering nominal pin diameters from 5 mm to 50 mm. The document is the 2016 second edition (minor revision) and recommends metric dimensions as the future standard for these reamers.

Key topics and technical requirements

• Dimensional requirements: The standard fixes dimensions and tolerances for features such as cutting diameter (d), taper diameters, taper length (t), usable length (l), overall length (L), and reference distances (y, y1). Specific numeric values are given in the table of dimensions for each nominal size.
• Morse taper shanks: Reamers are specified with Morse taper connection sizes appropriate to the reamer diameter; the standard identifies the Morse taper number for each reamer size.
• Cutting direction and flute options:
  • Unless otherwise stated, reamers are right‑hand cutting.
  • Flutes may be straight or left‑hand spiral, at the manufacturer’s option.
• Intended fit: Reamers are designed to produce holes for taper pins per ISO 2339.
• Data mapping: Annex A provides a relationship between the standard’s designations and the ISO 13399 tool-data dictionary (useful for tool data exchange and CAM/CAD libraries).
• Scope limits: Only machine reamers with Morse taper shanks are covered (hand reamers are covered by ISO 3465, and machine reamers with parallel shanks by ISO 3466).

Applications and users

• Manufacturing and machining operations that require accurate tapered-pin holes-typical users include:
  • Tool and cutter manufacturers producing reamers to standard dimensions
  • Machine shops and production engineers specifying reamers for jigs, fixtures, and assemblies
  • Maintenance and assembly technicians using taper pins for precise location and fastening
  • Procurement and quality control teams ensuring purchased reamers conform to international dimensions
  • CAM/CAD library authors and ERP systems using ISO 13399 mapping for tooling data exchange
• Typical applications: precision alignment, mechanical joints using taper pins, repair and refurbishment of machinery where standardized tapered-pin reamers ensure interchangeability.
