Full title and description

St ISO 7079-2016 — Core drills with parallel shanks and with Morse taper shanks. This International Standard specifies preferred diameters and corresponding length ranges for core drills supplied with either parallel shanks or Morse taper shanks.

Abstract

ISO 7079:2016 defines the dimensional specifications for core drills with parallel shanks and for core drills with Morse taper shanks. It provides tables of preferred diameters and corresponding length ranges (given as functions of diameter ranges), shows metric dimensions only, and assumes drills are right‑hand cutting unless otherwise stated.

Scope

This standard specifies the dimensions of core drills with parallel shanks and core drills with Morse taper shanks. It supplies tables with preferred diameters and the corresponding overall/working lengths expressed in diameter ranges, uses metric dimensions (recommended as the future sole system) and generally applies to right‑hand cutting drills unless stated otherwise. The standard is produced by ISO/TC 29/SC 9 (tools with defined cutting edges).

Key topics and requirements

• Preferred diameters for core drills (metric values) and standardized diameter steps.
• Corresponding length tables expressed as functions of diameter ranges (overall/working lengths).
• Specification of two shank types covered: parallel shanks and Morse taper shanks.
• Right‑hand cutting orientation assumed unless otherwise specified.
• Compatibility and cross‑reference with other drill standards (dimensions, lengths, tapers) used in tooling and manufacturing.

Typical use and users

Used by tooling manufacturers, drill and cutter designers, machine‑tool engineers, purchasers of cutting tools, quality and inspection personnel, and standards committees to ensure interchangeability, consistent sizing and clear specification when selecting or producing core drills with parallel or Morse taper shanks.

Related standards

ISO 7079 is in the family of ISO standards covering drills and drill shanks; closely related standards include ISO 235 (parallel shank jobber/stub series and Morse taper shank drills), ISO 3291 (extra‑long Morse taper shank twist drills) and ISO 3292 (extra‑long parallel shank twist drills). These related standards provide complementary dimensional series, length classes and special‑purpose drill definitions.

FAQ

Q: What is this standard?

A: ISO 7079:2016 is an International Standard that specifies dimensional requirements (preferred diameters and length ranges) for core drills with parallel shanks and for core drills with Morse taper shanks.

Q: What does it cover?

A: It covers metric preferred diameters, corresponding overall and working lengths expressed by diameter ranges, shank‑type definitions (parallel and Morse taper), and assumes right‑hand cutting unless otherwise stated. It provides tables with the standardized dimensions to be used by manufacturers and users of core drills.

Q: Who typically uses it?

A: Toolmakers, drill manufacturers, machine designers, procurement specialists, inspection and quality engineers, and standards committees involved in specifying or producing core drills for industrial and manufacturing applications.

Q: Is it current or superseded?

A: ISO 7079:2016 is the current published edition (edition 2, published October 2016). The earlier ISO 7079:1981 was withdrawn and replaced by the 2016 edition; ISO standards are typically reviewed on a five‑year cycle.

Q: Is it part of a series?

A: It is part of the body of ISO standards for drills and cutting‑tool shanks produced by ISO/TC 29/SC 9 and is commonly used alongside standards such as ISO 235, ISO 3291 and ISO 3292 which define related drill types and length classes.

Q: What are the key keywords?

A: Core drills; parallel shank; Morse taper; preferred diameters; drill lengths; metric dimensions; ISO 7079:2016; cutting tools.
