Product: TEMCo THA005 3-1/2" Conduit Punch and Die For Hydraulic Knock Out Driver 3/4"-16 Thread
Brand: Temco
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.

This set includes a single punch and die set. Punch die sizes are equal to conduit tube sizes. Can be used with TEMCo, Greenlee, or any other knock out punch set.
