This British Standard 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 diameters and
- the corresponding lengths defined in terms of diameter ranges.
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.
