Nothing Less.™ Review: Excelente , cumple con su Función Review: Not only does it cut a perfect hole it cuts the slug in two pieces so it just falls out, instade of having to fight with it. the cutter housing turns on a bearing while pulling the cutting bit through the metal. We used it on Stainless steel with no problems. Make sure you have a good drill bit for metal, for the pilot hole, then use a step drillbit to get to the proper size for the threads to go through. When cutting bit does not slip and is very smooth. ## Features - MANUAL KNOCKOUT KIT: Made for use with the new Greenlee KRW-1 High-Leverage Ratchet Wrench and includes 1/2", 3/4", 1", and 1-1/4" slug buster punches and dies, draw studs, and a carrying case - PUNCHES A VARIETY OF MATERIAL: Makes it easy to create punch holes for most conduit sizes in mild steel, up to 10-gauge aluminum, brass, copper, fiberglass, and plastics - USER-FRIENDLY DESIGN: Slug-Buster punch profile allows for easier slug removal, and the ergonomic knurled edge on the punches provides a firm, comfortable grip during use - CONVENIENT MARKINGS: Each piece features laser markings so you can quickly identify the tool needed and alignment markings for optimal accuracy - ELIMINATES CROSS THREADING: Draw studs with "dog point" tips make threading a breeze and help eliminate cross-threading for a superior performance every time ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000LDEZNO | | ASIN | B000LDEZNO | | Batteries Included? | No | | Batteries Required? | No | | Color | Green | | Country of origin | China | | Customer Reviews | 4.7 4.7 out of 5 stars (185) | | Customer reviews | 4.7 4.7 out of 5 stars (185) | | Date First Available | 15 September 2023 | | Date First Available | 15 September 2023 | | Department | Conduit & PVC Tools | | Included components | Unit^Instruction Guide | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 1.34 Kilograms | | Item model number | 7235BB | | Item model number | 7235BB | | Manufacturer | Greenlee | | Manufacturer | Greenlee | | Material | Manual Knockout Set | | Measurement System | Inch | | Number of Holes | 4 | | Part number | 7235BB | | Product Dimensions | 25.4 x 25.4 x 30.48 cm; 1.34 kg | | Product Dimensions | 25.4 x 25.4 x 30.48 cm; 1.34 kg | | Size | 1/2" - 1-1/4" conduit size knockouts (hole size: 0.89" - 1.70" or 22.5 mm - 43.2 mm) | | Style | Knockout Kit | ## Product Details - **Brand:** Greenlee - **Colour:** Green - **Item weight:** 1.34 kg - **Material:** Manual Knockout Set - **Product dimensions:** 30.5L x 22.9W x 6.4H centimeters ## Images ![7235BB Knockout Kit Hole Punch Set, 10 Piece, 10, 12 ga.

Or will doing that tend to break the studs?** A: I wouldnt do it to mine. If i wanted to use a drill, I'd grab my hole saws. It probably would depend on what gauge/type of metal you are punching out. I broke my 1/2" die using a wrench on a stainless panel. **Q: Is there a knockout for 1-1/2" stainless steel? If so, what is the part number?** A: yes there is for the 1 1/2" and 2" just check on amazon and it will come showing you the kit **Q: Are all of the knockouts slug busters, or is the picture right?** A: the picture is not correct it shows 735BB knockout punch set which contains only one slug buster. The item for sale is the 7235BB slugbuster set which contains four slug busters. **Q: what drill size is needed for the small bolt? And what is the punch size that the bolt fits?** A: For the small bolt you need open a hole of 7/16" This bolt is basically for the 1/2" conduit punch ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***S on 15 April 2019* Excelente , cumple con su Función ### ⭐⭐⭐⭐⭐ Review *by J***1 on 3 May 2019* Not only does it cut a perfect hole it cuts the slug in two pieces so it just falls out, instade of having to fight with it. the cutter housing turns on a bearing while pulling the cutting bit through the metal. We used it on Stainless steel with no problems. Make sure you have a good drill bit for metal, for the pilot hole, then use a step drillbit to get to the proper size for the threads to go through. When cutting bit does not slip and is very smooth. ### ⭐⭐⭐⭐⭐ Review *by D***D on 20 June 2016* Use the 3/4 inch (nominal size) and the Arlington grommets for fishing pipework and wiring through steel track and for new knockouts in the studs. A good solution if you're not looking to by the steel stud punch for 500+ dollars to do almost the same job. This kit also has a few different sizes so it can be useful for other projects. ## Frequently Bought Together - Greenlee 7235BB Slug-Buster 1/2" - 1-1/4" Manual Knockout Set for Use With KRW-1 High-Leverage Ratchet Wrench, Hole Punching Knockout Kit - Klein Tools 32500 11-in-1 Screwdriver / Nut Driver Set, 8 Bits (Phillips, Slotted, Torx, Square), 3 Nut Driver Sizes, Cushion Grip Handle - Dipped Plier Kit, Diagonal-Cutting, Needle-Nose, Side-Cutting High Leverage Linesman Pliers, Cutter and Crimper, 5-Piece --- ## 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.it/products/270156501-7235bb-knockout-kit-hole-punch-set-10-piece-10-12](https://www.desertcart.it/products/270156501-7235bb-knockout-kit-hole-punch-set-10-piece-10-12) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-14*
