Your cart is empty. TEMCo's hydraulic knock out punch sets have been a popular tool for both electricians and at-home DIYers. Now, we're happy to offer you individual punch and dies. You can use them with the knockout punch set you already have on hand, whether it's a trusty TEMCo, Greenlee, or any other brand.
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").
