Ironworker punch recommendation

Something to keep in mind when selecting punches is to make sure you use the right  punch for the purpose. A common use for a punch is to make holes for attaching bolts to a second work piece. If this hole is for a bolt you should use a punch 1/16″ larger than the bolt you plan to use. This will make sure that the bolt will go through the hole without problems. So for a 1/2″ hole you should use a 9/16th punch.
