Full title and description

St ISO 1641-3-1978 rus — International standard ISO 1641-3:1978 translated/adopted in Russian. Full title: "End mills and slot drills — Part 3: Milling cutters with 7/24 taper shanks". The document specifies dimensions and designation practices for end mills and slot drills that use a 7/24 taper shank.

Abstract

This standard (edition 1, 1978) defines the general dimensional parameters and designation conventions for milling cutters with 7/24 taper shanks, covering end mills (flat-ended and ball-nosed) and slot drills in the sizes/series given in the text. It was later revised by subsequent editions (notably ISO 1641-3:2003 and ISO 1641-3:2011). The Russian-language rendering (St ISO 1641-3-1978 rus) is a national-language copy/offer of that 1978 edition.

• Number of pages: 3 pages (original ISO pamphlet/leaflet format).

Scope

Specifies dimensions and designation for end mills and slot drills fitted with 7/24 taper shanks, including size series and variants (flat-ended, ball-nosed, slot drills, and series lengths). It gives the dimensional data necessary for interchangeability and correct designation of these tools, and references related shank standards for manual and automatic tool changers.

Key topics and requirements

• Dimensional specifications for milling cutters using 7/24 taper shanks (key diameters, lengths, taper interface data).
• Designation rules and nomenclature for end mills and slot drills (series, length designations, special forms).
• Classification of tool types covered: flat-ended end mills, ball-nosed end mills, slot drills, normal and long series where applicable.
• References to compatible shank/holder standards (for example ISO 297 and later ISO 7388 parts for automatic changers as referenced in later revisions).
• Interchangeability guidance to ensure suppliers and users adopt consistent nominal dimensions and designations.

Typical use and users

Used by tool designers and manufacturers, precision machine shops, tooling procurement and specification engineers, quality assurance and inspection personnel, and technical libraries. Typical activities: specifying cutter procurement, checking dimensional conformity, creating tool lists for CAM/CNC setups, and ensuring interchangeability with machine tool holders.

FAQ

Q: What is this standard?

A: ISO 1641-3:1978 is the part of the ISO 1641 series that defines dimensions and designation for milling cutters with 7/24 taper shanks; "St ISO 1641-3-1978 rus" denotes a Russian-language rendering or offering of that 1978 edition.

Q: What does it cover?

A: It covers dimensional data and designation conventions for end mills and slot drills fitted with 7/24 taper shanks (types, series, and nominal sizes) to permit interchangeability and consistent specification.

Q: Who typically uses it?

A: Tool manufacturers, machine shops, procurement/specification engineers, metrology/quality departments, and anyone involved in selecting or specifying milling cutters and their holders.

Q: Is it current or superseded?

A: The 1978 edition is withdrawn and has been superseded by later revisions (ISO 1641-3:2003 and the current ISO 1641-3:2011). Users should consult the latest edition for current requirements.

Q: Is it part of a series?

A: Yes — ISO 1641 is a multi-part series covering end mills and slot drills (parts for cylindrical shanks, Morse taper shanks, and 7/24 taper shanks among others); see ISO 1641-1, ISO 1641-2 and ISO 1641-3 (and their later revisions).
