ISO 1641-1:2016 specifies the general dimensions of the following milling cutters with plain cylindrical, flatted cylindrical and threaded shanks:

- end mills, flat-ended or ball-nosed: standard series and long series;

- slot drills : short series and standard series.

The dimensional characteristics of cylindrical shanks are in accordance with ISO 3338‑1, ISO 3338‑2 and ISO 3338‑3.

NOTE These same milling cutters with Morse taper shanks having a tapped hole are dealt with in ISO 1641‑2, those with 7/24 taper shanks in ISO 1641‑3.

ISO 1641-1:2016 does not apply to solid hard metal end mills and slot drills.
