But if you wanted a higher level of accuracy you may need to look elsewhere. The head on the drill bit is slightly curved so you wouldn't be able to pin point the exact spot of drilling, but like i said perfect for my needs and very cheap too. My main issue though was that they came to me covered in machining oil so i did have to clean them thoroughly first. ### ⭐⭐⭐⭐⭐ Perfect. *by L***L on Reviewed in the United Kingdom 🇬🇧 on 9 February 2019* Does exactly what it says on the tin. I needed to add a splash guard in my bathroom as a member of my family is quite liberal with the amount of water is splashed whenever she uses the shower, resulting in water stains on my kitchen ceiling, below the bathroom. I needed to drill through wall tiles and theses drill bits when through the tiles in seconds without chipping them. Perfect. ### ⭐⭐⭐⭐ Acceptable quality and good price *by D***9 on Reviewed in the United Kingdom 🇬🇧 on 9 July 2019* Packaging was unexciting but does the job --- ## 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.vn/products/68816975-tian-6pcs-high-hardness-titanium-coated-carbide-alloy-glass-drill](https://www.desertcart.vn/products/68816975-tian-6pcs-high-hardness-titanium-coated-carbide-alloy-glass-drill) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-22*
