Описание (английский):

ISO 3294:2016 specifies the dimensions of parallel shank countersinks for angles 60°, 90° and 120° inclusive. It specifies dimensions in metric units only, these being regarded as the only recommended dimensions in the future, for countersinks with cutting diameters in the range 8 mm to 25 mm. The dimensions apply only to tools made from high-speed steel. However, if the method of production allows, the shanks may be manufactured from a suitable alternative material, such as a carbon steel. Unless otherwise indicated, the countersinks will be right-hand cutting. Morse taper shank countersinks are the subject of ISO 3293.

Overview

ISO 3294:2016 defines standardized dimensions for parallel shank countersinks with point angles of 60°, 90° and 120°. The standard applies to countersinks with cutting diameters from 8 mm to 25 mm, specifies metric dimensions only, and is intended primarily for tools made from high‑speed steel (HSS). Unless otherwise stated, countersinks are right‑hand cutting and the front‑end design is optional. Morse‑taper shank variants are covered separately in ISO 3293.

Key topics

Scope and geometry

Point angles: 60°, 90° and 120° (inclusive).
Nominal cutting diameters: 8, 10, 12.5, 16, 20, 25 mm.

Dimensional data

The standard provides a dimensional table specifying overall length, body length and shank diameter for each nominal cutter size.
Overall lengths range from 48 mm (8 mm cutter) to 69 mm (25 mm cutter).
Body lengths are specified (e.g., 44 mm to 65 mm) and small relief diameters vary from 1.6 mm to 7 mm, depending on nominal size.
Shank diameters: 8 mm for 8–12.5 mm cutters, 10 mm for 16–25 mm cutters.

Materials and production

Tools are specified for high‑speed steel (HSS). Where production methods allow, shanks may be made of a suitable alternative (for example, carbon steel).

Default direction

Right‑hand cutting unless otherwise indicated.

Data exchange

Annex A maps ISO 3294 designations to preferred symbols in ISO 13399 (cutting tool data representation).

Applications

ISO 3294 is practical for organizations and professionals who design, manufacture, select or inspect countersinks used in:

Precision machining and metalworking (deburring, countersinking for fasteners)

Automotive and aerospace component production

Tool and cutter manufacturers and tooling engineers

CNC programmers and process planners specifying tooling lists

Purchasing and quality assurance teams requiring standardized tool dimensions

Using ISO 3294 ensures interchangeability, clear procurement specifications, and consistent fit for assembly operations that require standardized countersink geometry.
