Note When drilling, the drilled holes must not be repeated again. Otherwise, the drilled holes cannot be rounded, and the inside of the drilled holes will be blocked by paper scraps.

When the product is rotating, it is strictly prohibited to touch it by hand. Feature Straight shank (H): Installed on the machine with screws ( need to be screwed). Easy to disassemble. Review: Great for quick and dirty bookbinding. - I made some decorated blank book journals and used this to drill three holes each for binding with post screw sets. This thing went right through 22 sheets of 100# cardstock plus two pieces of that dense thin cardboard that's basically 1/16" thick cereal box. After about a dozen holes it filled up very tightly and I had to use a smaller conventional drill to get all the paper punches out but that wasn't a big deal. One tip I discovered that prevented bulging on the bottom side is to place a piece of pine board under the project instead of on the drill table hole. Review: Quality - This hole punch is Chinese. The sheath it comes with has Chinese letters on it. That said this thing is awesome. I bought it to use in my drill press but didn't even need to. It is sharp! I've punched 1000s of pages with it now. I just flip a notebook upside down and drill holes in sheets where I want with my hand. Works really good. 50pages at a time. I imagine the drill press would make much shorter work of it though. ## Features - 【Product details】- Punching dia.: 7mm / 0.28-inch; punching length: 40mm / 1.57-inch; shank dia.: 11mm / 0.43-inch; total length: 75mm / 2.95-inch.

I just punched through over 50 pages using a 3d-printed guide and hammering the punch drill as if it were a nail all through the pages. It worked great. Be careful, it is very sharp. --- ## 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/743931844-utoolmart-7mm-paper-punch-drill-straight-shank-hollow-bit-tool](https://www.desertcart.tn/products/743931844-utoolmart-7mm-paper-punch-drill-straight-shank-hollow-bit-tool) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-14*
