Cylindrical shanks for milling cutters — Part 2: Dimensional characteristics of flatted cylindrical shanks
ISO 3338-2:2013 specifies the dimensions of flatted cylindrical shanks for milling cutters, of diameters 6 mm to 20 mm for single-flatted shanks, of 25 mm to 63 mm for double-flatted shanks and of 6 mm to 32 mm for shank with inclined clamping surface. In the case of single-flatted shanks, it is applicable to both single-ended cutters and double-ended cutters, as double-flatted shanks cannot admit single-ended cutters. The dimensions of plain cylindrical shanks and threaded shanks are given in ISO 3338-1 and ISO 3338-3, respectively. The two shank types covered by ISO 3338-1 and ISO 3338-2:2013 have the same dimensional characteristics (diameters and lengths), but different tolerances on diameters.
Queues cylindriques d'outils à fraiser — Partie 2: Caractéristiques dimensionnelles des queues cylindriques à méplat
L'ISO 3338-2:2013 spécifie les dimensions des queues cylindriques à méplat d'outils à fraiser (de diamètres 6 mm à 20 mm pour les queues à méplat unique, de diamètres 25 mm à 63 mm pour les queues à double méplat et de diamètres 6 mm à 32 mm pour les queues cylindriques à surface de serrage inclinée). Dans le cas des queues à méplat unique, elle est applicable aussi bien pour les fraises simples que pour les fraises doubles, les queues à double méplat ne pouvant pas admettre des fraises simples. Les dimensions des queues cylindriques lisses et des queues cylindriques filetées font l'objet de l'ISO 3338‑1 et de l'ISO 3338‑3, respectivement. Les deux types de queues faisant l'objet de l'ISO 3338‑1 et l'ISO 3338 2:2013 ont les mêmes caractéristiques dimensionnelles (diamètres et longueurs) à l'exception des tolérances à appliquer aux diamètres.

Overview
ISO 3338-2:2013 – Cylindrical shanks for milling cutters - Part 2: Dimensional characteristics of flatted cylindrical shanks is an international standard developed by ISO. It defines the dimensional requirements for flatted cylindrical shanks used in milling cutters. The standard covers shanks with single and double flats, designed to ensure reliable mounting, secure clamping, and global interchangeability. By specifying diameters, lengths, and tolerance classes, ISO 3338-2:2013 supports consistent manufacturing quality and compatibility across the precision tooling and machining industries.
Key Topics
Dimensional Specifications
ISO 3338-2:2013 details the dimensions for three forms of flatted cylindrical shanks:- Single-flatted shanks (diameters 6 mm to 20 mm)
- Double-flatted shanks (diameters 25 mm to 63 mm)
- Shanks with inclined clamping surfaces (diameters 6 mm to 32 mm)
Applicability to Cutter Types
- Single-flatted shanks apply to both single-ended and double-ended milling cutters
- Double-flatted shanks are not suitable for single-ended cutters
Tolerance Classes
The standard distinguishes between:- h6 tolerance for flatted cylindrical shanks (as per this part)
- h8 tolerance for plain cylindrical shanks (covered in ISO 3338-1)
Reference to Other Parts
- Plain cylindrical shank dimensions are specified in ISO 3338-1
- Threaded shank dimensions are specified in ISO 3338-3
Relationship to ISO 13399
Includes an annex mapping dimensional symbols to ISO 13399 properties for data exchange in tooling databases.
Applications
ISO 3338-2:2013 is essential in industries where milling cutters are a core process component, such as metalworking, automotive manufacturing, and aerospace engineering. The standard’s specifications provide benefits including:
Tool Manufacturer Guidance
Ensures compatibility and interchangeability of milling cutter shanks across multiple brands and markets.Secure Clamping Solutions
Flatted shank designs provide improved stability and resistance to rotational forces during usage, supporting higher precision in machining operations.Procurement and Quality Assurance
Manufacturers and buyers can reference ISO 3338-2 standards to verify product dimensions, tolerances, and suitability, streamlining supplier compliance and inspection processes.Integration with Digital Tooling Data
The alignment with ISO 13399 symbol references supports digital integration for computer-aided design (CAD/CAM), tool management systems, and digital manufacturing workflows.
