Full title and description

End mills with brazed helical hardmetal tips — Part 2: Dimensions of end mills with 7/24 taper shank. This ISO standard specifies the general dimensional requirements for two types of end mills with a 7/24 taper shank (for manual changing and for automatic tool changers) and applies to right‑ and left‑hand end mills irrespective of helix angle and number of flutes.

Abstract

ISO 10145-2:2016 defines the nominal dimensions and principal designations for end mills fitted with brazed helical hardmetal tips and using a 7/24 taper shank. It covers end mills intended for manual tool change and those intended for use with automatic tool changers, and is limited to the dimensional specification rather than tool material, coatings or cutting performance.

Scope

ISO 10145-2:2016 specifies the general dimensions of end mills with brazed helical hardmetal tips having a 7/24 taper shank. The standard applies to two types of shank arrangements: end mills with 7/24 taper shank for manual changing (spindle/tool interfaces covered by older 7/24 taper practice) and end mills with 7/24 taper shank designed for use with automatic tool changers. It covers right‑hand and left‑hand cutters, independent of helix angle and number of flutes, and focuses on dimensional interchangeability rather than performance characteristics.

Key topics and requirements

• Definition of dimensional parameters for end mills with brazed helical hardmetal tips using a 7/24 taper shank (nominal diameters, lengths, flange/collar positions and key shank features).
• Separate designation of two types: shanks for manual changing and shanks for automatic tool changers.
• Interchangeability focus — dimensions intended to ensure compatibility with spindle noses and tool holders that use 7/24 taper interfaces.
• References and normative linkage to related taper standards for manual and automatic systems (for manual 7/24 taper practice see ISO 297; for automatic tool changer shank forms and dimensions see ISO 7388‑1).
• Applies equally to right‑hand and left‑hand end mills and is independent of helix angle and number of flutes.

Typical use and users

Used by cutting tool manufacturers, tool designers, machine tool builders, quality and inspection teams, procurement/specification engineers, and standards committees. Typical applications include specifying catalogue tooling dimensions, ensuring interchangeability between tools and toolholders, engineering drawings for tool production, and procurement specifications for milling cutters with 7/24 taper shanks.

Related standards

Standards commonly referenced alongside ISO 10145-2:2016 include ISO 10145-1:2016 (Part 1 — dimensions of end mills with parallel shank), ISO 297 (7/24 tapers for tool shanks for manual changing) and ISO 7388‑1 (tool shanks with 7/24 taper for automatic tool changers — dimensions and designation). These related documents define complementary shank and spindle/taper practices and are used together to ensure mechanical interchangeability.

FAQ

Q: What is this standard?

A: ISO 10145-2:2016 is an international standard that sets out the dimensional specifications for end mills with brazed helical hardmetal tips that use a 7/24 taper shank.

Q: What does it cover?

A: It covers the general dimensions and designation of two types of end mills with 7/24 taper shank — those for manual changing and those for automatic tool changers — and applies to right‑ and left‑hand cutters regardless of helix angle or number of flutes.

Q: Who typically uses it?

A: Cutting tool manufacturers, machine tool designers, procurement and specification engineers, inspection and metrology personnel, and standards committees use this standard to ensure dimensional interchangeability and to specify tool/shank dimensions in drawings and catalogues.

Q: Is it current or superseded?

A: The 2016 edition (Edition 2) is the current published edition; the ISO bibliographic record shows the 2016 edition as published and later confirmed in the ISO review cycle. The 1993 edition was withdrawn and replaced by the 2016 edition.

Q: Is it part of a series?

A: Yes — ISO 10145 is a multipart standard. ISO 10145-1:2016 (Part 1) covers dimensions of end mills with parallel shank, and ISO 10145-2:2016 is Part 2 for 7/24 taper shank dimensions.

Q: What are the key keywords?

A: End mill, brazed hardmetal tip, helical cutting edge, 7/24 taper, taper shank, dimensions, interchangeability, ISO 10145-2:2016.
