Our punch dies are sized to conduit sizes, not actual hole sizes. Electricians use these sizes because conduits are measured by the inner diameter of the tube, not their outer diameter. That means, for example, a 1" punch die will correctly punch for a 1" conduit tube (which has an actual hole size of roughly 1.33"). We've provided you with a handy table below that shows the actual hole size produced by our punch die/conduit sizes in this set. Fits Driver: Old Style TEMCo TH0037
