Overview
ISO 3337:2000 is an International Standard that specifies the dimensional requirements for T-slot cutters used to manufacture T-slots on machine tools and equipment in accordance with ISO 299. The standard covers cutters with: plain cylindrical shanks, flatted cylindrical shanks, threaded shanks and Morse taper shanks with a tapped hole. This third edition updates earlier versions and explicitly includes threaded shanks.
Key Topics
- Scope and applicability: T-slot cutters intended for producing T-slots in machine-tool tables and fixtures per ISO 299.
- Shank types covered: plain cylindrical, cylindrical with flats, threaded shanks, and Morse taper shanks with tapped hole.
- Size ranges:
- Cylindrical (plain or flatted) and threaded shanks: suitable for slot widths from 5 mm to 36 mm inclusive.
- Morse taper shanks with tapped hole: suitable for slot widths from 10 mm to 54 mm inclusive.
- Reference standards: the standard points to related ISO documents for shank dimensional characteristics and tool mounting compatibility, including ISO 296, ISO 299, and ISO 3338-1/2/3.
Practical takeaways:
- Ensures dimensional interchangeability of cutters across suppliers and machine-tool setups.
- Standardized shank dimensions facilitate secure mounting and predictable performance.
Applications
ISO 3337:2000 is primarily used by:
- Tool manufacturers designing and producing T-slot cutters to standardized dimensions.
- Machine shops and production facilities specifying tooling for milling operations that create T-slots in tables, fixtures, and equipment.
- Purchasing and quality teams verifying conformity of cutters to ensure fit with ISO 299 T-slot profiles.
Typical applications include the manufacture and repair of machine-tool tables, jigs and fixtures where standardized T-slot profiles are required for clamping and modular fixturing.
Related Standards
- ISO 299 - Defines T-slot profiles and corresponding bolts used in machine-tool tables; ISO 3337 cutters are intended to produce slots conforming to this standard.
- ISO 296 - Covers Morse taper dimensions relevant to cutters with Morse taper shanks.
- ISO 3338-1 / -2 / -3 - Provide dimensional characteristics for plain cylindrical shanks, cylindrical shanks with flats, and threaded shanks respectively.

For specification, procurement, and compliance activities, ISO 3337:2000 provides the essential dimensional framework to ensure safe, interoperable, and repeatable T-slot machining across equipment and suppliers.
