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. Make the drilling process easier. - ✅【Wide Usage】：This glass drill bit set contains 15 different drill bits to meet various needs. It is used to drill hard surfaces such as glass, wood, ceramic tile bottles, block jars, ceramics, slate, granite pumice, etc. - ⚠【Note】: When cutting hard materials, be sure to keep the tool cool to avoid damage to the material being drilled and premature wear of the tool; water lubrication is required when drilling, which can prolong the service life of the drill set. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B097YKFV5S | | Best Sellers Rank | 3,016 in DIY & Tools ( See Top 100 in DIY & Tools ) 13 in Hole Saws | | Brand | flintronic | | Colour | 15 pieces (8-50mm) | | Compatible Devices | Electric drills with a suitable chuck size | | Compatible Material | Porcelain | | Country Of Origin | China | | Customer Reviews | 4.1 out of 5 stars 3,917 Reviews | | Item Weight | 350 Grams | | Item weight | 350 Grams | | Manufacturer | flintronic®-uk | | Manufacturer Part Number | F4EU-2946477 | | Material | Carbon Steel , Diamond | | Number of Items | 15 | | Number of Teeth | 15 | | Number of teeth | 15 | | Set Name | Flintronic 15-Piece Diamond Drill Bit Set (8mm-50mm) | | Style | Industrial | | Style Name | Industrial | ## Product Details - **Material:** Carbon Steel, Diamond - **Brand:** flintronic - **Colour:** 15PCS(8mm-50mm) - **Number of teeth:** 15 - **Style:** Industrial - **Item weight:** 350 Grams ## Images ![Flintronic Diamond Drill Bit Set, 15PCS(8mm-50mm) Tile Hole Cutter Set | Tile Drill Bits, Carbon Steel Hole Saw Cutter Tools Sets for Glass/Tiles/Ceramic/Marble/Porcelain Cutting - Image 1](https://m.media-amazon.com/images/I/71KpuDcg5rL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good! *by D***M on 1 July 2026* These were amazing with wet sponge, never done tile cutting/drilling before - popped it into screwdriver and at an angle and it did a great job with lots of different tiles without any loss of wear.

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.tn/products/369138534-flintronic-diamond-drill-bit-set-15pcs-8mm-50mm-tile-hole](https://www.desertcart.tn/products/369138534-flintronic-diamond-drill-bit-set-15pcs-8mm-50mm-tile-hole) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-06*
