Gives dimensions of core drills with parallel shanks and with Morse taper shanks, and recommendations for stock removal for core drills for pre-finishing operations.

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:
