Check out the data sheet! The Greenlee 28155 Slug - Splitter Die is a top - notch tool for punching holes in conduits. Here are its specifications: The hole sizes are based on the outside diameter of US conduit sizes. For example, a 1/2 - inch conduit size punch creates a 7/8 - inch hole. The corresponding punch is 28154, and the draw studs are 29451 (for hydraulic drivers like 7804, 7904, 7646, 7625) and 30227 (for the ratchet driver 1904). This die comes with amazing features. Its heavy - duty slug - splitter punches can go through 10 - gauge (3.5 mm) stainless steel. The unique slug - splitting design and tool - steel construction make it a breeze to punch through 10 - gauge mild steel and stainless steel. The self - centering punch aligns itself on the pilot hole, so you don't have to draw crosshairs or line up die alignment marks. The special punch profile also splits slugs, making their removal super easy. With heavy - duty dies and stainless - steel draw studs, it has a long lifespan. It offers excellent abrasion resistance for punching fiberglass and plastic. It can only be operated with a battery, hydraulic, or high - leverage ratchet driver. And it's patent - pending!

If you notice any damage, replace the parts immediately. Store the die in a dry place to prevent rusting.
