NF ISO 7079

Core drills with parallel shanks and with Morse taper shanks

ISO 7079:2016 specifies the dimensions of core drills with parallel shanks and with Morse taper shanks.

It includes two tables for each of the above specified types, giving respectively

- the dimensions for the preferred diameter (see Tables 1 and 2), and

- the corresponding lengths defined in terms of diameter ranges (see Tables 3 and 4).

The tables show only metric dimensions which are alone recommended in the future for this type of drill.

Unless otherwise stated, these drills will be right-hand cutting drills.
