Overview
ISO 3338-1:1996 defines the dimensional characteristics of plain cylindrical shanks used on milling cutters. The standard applies to shank diameters from 3 mm to 63 mm and covers both single-ended and double-ended cutters. Dimensions are given in millimetres and presented in associated figures and tables (see figure 1 and table 1 in the standard).
This part of ISO 3338 focuses on plain (smooth) cylindrical shanks and establishes a common basis for design, manufacture and inspection of milling cutter shanks to support interchangeability and consistent tooling performance.
Key Topics
- Scope and applicability: plain cylindrical shanks for milling cutters with diameters 3–63 mm; single- and double-ended cutters.
- Dimensional data: reference to figure 1 and table 1 for nominal dimensions presented in millimetres.
- Conformity notes: cross-reference to related documents where applicable (for example, compatibility notes with rotating tools standards such as ISO 237:1975).
- Standardization benefits: supports repeatable manufacturing, simplified quality control and compatibility across toolholders and tool manufacturers.
Keywords: ISO 3338-1:1996, cylindrical shanks, milling cutters, dimensions, plain shanks, interchangeability, manufacturing accuracy.
Applications
ISO 3338-1:1996 is directly relevant to:
- Tool manufacturers designing and producing milling cutters with plain cylindrical shanks who require standardized dimensions for production planning and tooling.
- Tooling engineers selecting cutters for machine tools where shank dimensions must match collets, chucks or holders.
- Quality and inspection teams verifying dimensional conformity to international standards to ensure interchangeability.
- Procurement and specification writers who include standard references in purchase orders and technical specifications to guarantee compatibility across suppliers.
Practical benefits include reduced tooling mismatches, clearer supplier requirements, and easier integration of cutters into existing machining setups.
Related Standards
- ISO 3338-2: Dimensional characteristics of flatted cylindrical shanks (covers flatted shank variants).
- ISO 3338-3: Dimensional characteristics of threaded shanks (covers threaded shank variants).
- ISO 237:1975: Rotating tools with parallel shanks - referenced for square shank conformity and related rotating-tool guidance.
For implementers, referencing ISO 3338-1:1996 alongside ISO 3338-2 and ISO 3338-3 ensures comprehensive coverage of cylindrical shank forms and supports consistent tooling ecosystems across manufacturing and maintenance operations.
