Subland twist drills for holes prior to tapping screw threads1 Scope This International Standard specifies the dimensions of subland twist drills with Morse taper shanks and cylindrical shanks for holes prior to tapping screw threads. The drills are designed to produce holes prior to tapping metric threads (coarse pitch series) over a selected range of: M8 to M30 for subland twist drills with Morse taper shanks; M3 to M14 for subland twist drills with cylindrical shanks. This International Standard complements
