Review: Knockout punch - Worked perfectly on my AMZCNC hydraulic knockout punch that came with sizes 1/2” to 2” I’ll be buying the larger sizes as needed too. Review: This with a cordless impact driver makes life beautiful again :-) - Great set for the price. Used up to 2" so far with my Milwaukee impact driver and it's a beautiful thing when compared to a hole saw or paying $1500 for a dedicated cordless tool!

Used up to 2" so far with my Milwaukee impact driver and it's a beautiful thing when compared to a hole saw or paying $1500 for a dedicated cordless tool! Wish I would have bought it a long time ago! ### ⭐⭐⭐⭐⭐ 4" = 120mm fan sized *by R***K on July 9, 2026* Good punch set. It's going to make you work to get it through sheet steel if you only have a draw stud and a wrench, but it does work. If you're wondering like I did if a 4" size would work for a 120mm fan, I can confirm its nearly perfect sized for that use case. I bought it to punch some holes in my legrand on-q steel cabinet so I could add ventilation fans and it seems to work for that. --- ## 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.tn/products/489278010-amzcnc-hydraulic-knockout-punch-die-4-3-4-16un-conduit](https://www.desertcart.tn/products/489278010-amzcnc-hydraulic-knockout-punch-die-4-3-4-16un-conduit) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-28*
