Type 304 stainless steel. Cuts better than the old-style punches and far easier to clear slugs. ### ⭐⭐⭐⭐⭐ ordered 1/2 inch, recieved 3/4 *by B***Y on October 13, 2018* never a problem with Greenlee, best knockout, slug buster is by far the best. Just the wrong size, can't fault Greenlee. ### ⭐⭐⭐⭐⭐ great quality, quick shipment *by B***D on May 14, 2015* Exactly as described, great quality, quick shipment. Make sure to order the "Knockout Die" if replacing a worn/damaged set; this is only the punch side that has the cutting teeth and is pulled through the material you are punching. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/12972454-greenlee-721-1-2-punch-rd-500-conduit-22-5mm](https://www.desertcart.us/products/12972454-greenlee-721-1-2-punch-rd-500-conduit-22-5mm) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-06-09*
