ISO 7079:2016规定了直柄和莫氏锥柄取芯钻头的尺寸。 它包括两个表，分别针对上述指定类型给出 -首选直径的尺寸（见表1和表2），以及 -根据直径范围定义的相应长度（见表3和表4）。 表中仅显示了公制尺寸，这些尺寸在未来单独推荐用于此类钻机。 除非另有说明，否则这些钻头将为右手切削钻头。

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.
