Although they have wax in them which melts to keep them cool we also used water. ### ⭐⭐⭐⭐⭐ Fast , clean controlled cut *by on Reviewed in the United Kingdom 2 May 2022* Brilliant way of drilling tiles I used to use the wax 6mm core bits and I was lucky to get one bathroom out of one bit and there where £18 each . now I found these bits and there are more cost affective, double or triple the speed so can get as many holes done as I like in no time at all , I’m on my third porcelain tiled bathroom and the bit is still so sharp well worth it . A lot of people I no are put of with using a grinder and not a drill , don’t be !! give it a go practice first and you won’t look backThanks grant ### ⭐⭐⭐⭐⭐ Works fine on porcelain *by on Reviewed in the United Kingdom 19 June 2020* Bit worked a treat. Used on thick porcelain tiles and done a great job. So far it's done about 15 holes and has life left in it. This won't last forever but it's perfect for projects and a small price to pay for what it does, just bear in mind you must cool it with water as you drill. Do that and it will last and do a fast, smooth job. Just use an old spray bottle or similar and job done. --- ## 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.gr/products/51642811-rubi-dry-drilling-in-ceramic-porcelain-natural-stone-and-other](https://www.desertcart.gr/products/51642811-rubi-dry-drilling-in-ceramic-porcelain-natural-stone-and-other) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-14*
