Full title and description

STB BS ISO 10889-4:2016 — Tool holders with cylindrical shank — Part 4: Type C with rectangular axial seat. This entry corresponds to the international standard ISO 10889-4:2016 and its British adoption (BS ISO 10889-4:2016); no authoritative record was found for a distinct "STB" variant in public bibliographic sources, so the content below follows the ISO / BS ISO text and scope.

Abstract

Specifies dimensions, designation rules and complementary technical delivery conditions for tool holders with a cylindrical shank and a rectangular axial seat (Type C — forms C1 to C4). It is intended for tool holders used on machine tools with non-rotating tools, preferably for turning machines, and references general tolerancing standards (e.g., ISO 8015, ISO 2768) for unspecified tolerances.

Scope

Defines the geometrical dimensions, designation convention and complementary delivery conditions for Type C tool holders (forms C1–C4) having a rectangular axial seat with a cylindrical shank in accordance with ISO 10889‑1. Applicable to tool holders for machine tools with non‑rotating tools (preferably turning machines). The part is intended to be used where standardized mounting and interchangeability of tool holders is required.

Key topics and requirements

• Definition of Type C forms (C1 to C4) and their graphical representations and dimensions.
• Tabulated nominal dimensions and tolerances expressed in millimetres.
• Designation rules for marking and ordering (type, nominal diameter, nominal height, and length conventions where applicable).
• Reference to general tolerancing standards (ISO 8015, ISO 2768) for unspecified tolerances and default tolerance classes.
• Complementary technical delivery conditions for conformity between manufacturers and purchasers.

Typical use and users

Used by machine tool designers, tool‑holder manufacturers, procurement/specification engineers, QA and inspection teams in manufacturing and maintenance, and standards librarians who manage standards collections. Typical applications include specifying interchangeability and procurement dimensions for turning tool holders and ensuring consistent technical delivery requirements across suppliers.

FAQ

Q: What is this standard?

A: ISO 10889‑4:2016 (published as BS ISO 10889‑4:2016 when adopted nationally by BSI) specifies dimensions and delivery conditions for tool holders with a cylindrical shank and a rectangular axial seat (Type C).

Q: What does it cover?

A: It covers the geometrical definitions, nominal dimensions, tolerances, designation/marking conventions and complementary technical delivery conditions for Type C tool holders (forms C1–C4), intended mainly for non‑rotating tools on turning machines.

Q: Who typically uses it?

A: Manufacturers of tool holders, machine tool builders, procurement and specification engineers, quality/inspection personnel and standards/technical libraries. These users apply the standard to ensure interchangeability and to specify delivery requirements.

Q: Is it current or superseded?

A: The 2016 edition (Edition 3) is the current ISO edition and was reviewed/confirmed in ISO's review cycle; national adoptions (e.g., BS ISO 10889‑4:2016) reflect that edition. If you require the absolute current legal status for procurement or regulatory compliance, check the issuing national body or ISO catalogue for any amendments or withdrawals.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 10889 series covering tool holders with cylindrical shanks; other parts cover different seat forms and accessories (see ISO 10889‑1 and subsequent parts).

Q: What are the key keywords?

A: Tool holder, cylindrical shank, rectangular axial seat, Type C, dimensions, tolerances, ISO 10889, technical delivery conditions.
