Problem : Many machines today use metric bolts and holes must be tapped in metric. is there an easy way to determine what metric drill size to use?
Solution : Subtract the thread pitch from the metric bolt size and you have the answer. For example, to drill for an 8-mm bolt with a pitch of 1.25 means the proper drill bit size is 6.75 mm. (8-1.25=6.75).
