Good stability and compatibility, cutting speed is good to my liking as it avoids mistakes. Size selection to what I needed was good. Appearance wise they do look well made and I will be lending those to my friend. Slight chipping but I'm blaming that on myself as that was the first tile cut. Review: Main hole cutter is great for the price, pilot bit is useless. - I bought this 35mm diamond hole cutter to go through a 20mm thick solid porcelain slab to install a tap. It’s a tough material to get through and thought I’d give this a go as the bargain price was worth the risk. Sadly the pilot bit in the middle of the cutter is completely useless, as it melted and disintegrated within 10 seconds of use. I removed the pilot then used the main cutter by holding it at an angle and slowly tilting up as I went. Very impressive cutting speed as it easily went through the porcelain in about 15 seconds. I’ll give this a 5 star rating despite the pilot drill failure as it did the job I needed without spending too much. Couldn’t see any wear on the diamond edge, so it would appear this may last for many more jobs than I would have expected. ## Features - 💎【High-quality Drill Bits】: These diamond drill bits are made of industrial-grade carbon steel, with a nickel-plated coating to resist corrosion; fine workmanship, super wear-resistant, and sharp. - 💎【 Diamond Coating Top】： Each hole is smooth and precise surface treatment, and the thick diamond coating on the top can provide excellent cutting strength to achieve the maximum drilling effect. - 💎【Large Clearance Holes】: These glass hole saws are arranged along the drill bit to facilitate the escape of chips and other particles when cooling water enters and drills.

I needed a few different sizes and looked on the Screwfix website as that is were I usually buy tools. A 5 piece set from Screwfix was 70 quid so I thought I'd try these first. I don't know how long the diamond edge will last but they cut through ceramic tiles without any problems. I used them in my pillar drill and they cut a clean accurate hole. Definitely worth the money. ## Frequently Bought Together - flintronic Diamond Drill Bit Set, 15PCS(8mm-50mm) Carbon Steel Hole Saw Cutter Tools Set for Glass/Tile/Ceramic/Marble/Porcelain Cutting - SabreCut SCTBA5 Multi-Material Tile Drill Bits Set for Ceramic Porcelain Granite Marble with Durable Storage Box - 10PCS Tile Drill Bits Set, Professional Drill Bits Set for Porcelain/Glass/Brick/Plastic/Cement/Wood/Tile/Etc, Industrial Strength Tile Drill Bits Set, All Size (3 4 5 6 6 6 6 8 10 12mm) --- ## 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/369138534-flintronic-diamond-drill-bit-set-15pcs-8mm-50mm-tile-hole](https://www.desertcart.vn/products/369138534-flintronic-diamond-drill-bit-set-15pcs-8mm-50mm-tile-hole) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-09-20*
