Bit worked great for three holes then started to get dull even with a slow speed and water being added regularly. Compared to other bits I purchased at a local home improvement store this bit worked great and other bits didn’t even start to penetrate the tile.I did find after five holes that the bit seemed to work better if I pulled the speed on and off and changed pressure slightly keep in mind you don’t want to drill at a high speed or with too much pressure. Overall a very good product. ### ⭐⭐⭐⭐⭐ Great bit *by on Reviewed in the United States June 22, 2013* Last time i tried to drill through Porcelain I used a cheap bit from the local hardware store which took 45 minutes to drill one hole.For this project I decided to spend the money on a good bit because I had 6 holes to drill for my shower door installation. Wow what a difference, i had all 6 holes drilled in twenty minutes and that included the time to double check the bit placement and alignment. Actual drill time was roughly 1 minute per hole! Just keep it wet and this thing drills through it like butter..Great product!! ### ⭐⭐⭐⭐ Good at first. *by on Reviewed in the United States May 24, 2015* The first few holes were very fast. didn't have the option of constant water surging onto the bit. Had to use a spray bottle. In porcelain tile it cut fast at first but under less than idea conditions it overheated and shattered. If you can't give it constant cooling it seems like it won't last. Quite expensive. --- ## 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.pe/products/18364792-armeg-3-16-ptc-carbide-porcelain-drill-bit](https://www.desertcart.pe/products/18364792-armeg-3-16-ptc-carbide-porcelain-drill-bit) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-08-15*
