I've used mine for electrical power panels. It would probably work on a thin sink but they sell stainless Punch's for stainless materials. **Q: Plastic knockouts are very difficult to remove from this tool. Is there an easy way to remove them for someone that may need to do a couple dozen/day?** A: The only thing I can think of is and making sure you're taking the punch completely off the threads before you try to remove the plastic and hopefully it's splitting them in two. Punch set but typically when I'm dealing with plastic I use a very good hole saw kit.. cuz I seen the plastic boxes split if they get extremely cold **Q: Can I use a 1/2" battery powered impact to drive the studs instead of the wrench? Or will the studs just break using an impact on em like that?** A: I've never used an impact and I wouldn't recommend it unless you are cutting through sheet metal or very thin walled steel or aluminium. **Q: where can i get the sockit wranch yep i lost it** A: https://www.toolup.com/Greenlee-34941-Slug-Buster-Knockout-Kit-Ratchet-Wrench-1-Hex ## Frequently Bought Together - Greenlee 7238SB Slug-Buster Knockout Punch Kit with Hex Ratchet Wrench, 1/2" to 2" Punches, and 7/16" and 3/4" Draw Studs, Electrical Conduit Hole Cutter Kit - Greenlee DTAPKIT Drill/Tap Kit for Metal, One-Step Drilling, Tapping, and Deburring/Countersinking Set with Quick Change Adaptor, 6-32 to 1/4-20 - Lenox Tools - T30802-1200L LENOX Tools Hole Saw Kit for Electricians, Speed Slot, 17 Piece ( 308021200L) --- ## 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/2813411-7238sb-slug-buster-knockout-punch-kit-with-hex-ratchet-wrench](https://www.desertcart.us/products/2813411-7238sb-slug-buster-knockout-punch-kit-with-hex-ratchet-wrench) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-04*
