BGTEC Dry Diamond Drill Bit Set (10 pcs, 6mm) – Detailed Review The BGTEC Dry Diamond Drill Bit Set is a specialized drilling solution designed for working with hard materials such as granite, marble, tile, ceramic, glass, and masonry. With its vacuum-brazed diamond technology and cooling wax core, this set aims to provide efficient, clean drilling without requiring constant water cooling. Build Quality & Design One of the standout features of this drill bit set is its vacuum-brazed diamond construction. This manufacturing method bonds diamond particles directly to the steel body, making the bits extremely durable and capable of cutting through dense materials. The bits have a round shank design, which makes them compatible with most standard drills. The build feels solid and well-engineered, and the included protective storage case keeps the bits organized and prevents damage during transport. Key design highlights include: Diamond-coated cutting edges for improved hardness and longevity Side cooling grooves to help remove debris and reduce overheating Wax-filled cores that melt during drilling to provide lubrication and cooling 118° cutting angle for precise drilling These features make the set suitable for both professionals and serious DIY users. Performance Performance is where this drill bit set really shines. When drilling into ceramic tile, porcelain, marble, or granite, the diamond edges provide smooth and accurate cuts with minimal chipping. The dry drilling capability is particularly convenient. Thanks to the wax cores inside each bit, you don’t always need water cooling. This makes the drilling process much easier, especially for quick installation jobs like: Bathroom tile drilling Kitchen backsplash installation Installing anchors in stone or masonry Glass drilling with controlled pressure However, when drilling harder materials for extended periods, light water cooling is still recommended to maximize bit lifespan. Durability The vacuum brazed diamond technology significantly improves durability compared to standard carbide drill bits. When used properly (moderate speed, steady pressure), the bits can last through multiple drilling jobs without losing effectiveness. Because diamond bits wear gradually rather than breaking suddenly, you’ll notice consistent performance for longer periods. Ease of Use This set is fairly beginner-friendly: Works with most handheld drills No specialized equipment required Dry drilling capability reduces setup time Clean holes with minimal cracking For best results: Start drilling at a slight angle. Once a groove forms, straighten the drill. Use moderate RPM and light pressure. This technique prevents slipping and improves accuracy. Value for Money Considering the set includes 10 pieces of diamond drill bits, the price point offers solid value. Diamond drilling tools can often be expensive, so getting a full set at this price is appealing for DIYers and contractors alike. You essentially get a reliable kit for drilling through multiple hard materials without purchasing individual bits. Pros ✔ Durable vacuum-brazed diamond construction ✔ Dry drilling capability with built-in wax cooling ✔ Works on many hard materials (tile, glass, granite, marble, concrete) ✔ Compatible with standard drills ✔ Good value for a 10-piece set ✔ Compact storage case included Cons ✖ Performance may drop if used at very high speeds ✖ Water cooling may still be needed for prolonged drilling in extremely hard stone ✖ Not ideal for hammer drilling Final Verdict The BGTEC Dry Diamond Drill Bit Set is a reliable and practical tool for anyone working with hard surfaces like tile, stone, and glass. Its diamond-coated design, cooling wax core, and durable construction make it a strong performer for both professional installers and DIY enthusiasts. If you frequently need to drill clean, precise holes in hard materials, this set offers excellent convenience, durability, and overall value. ⭐ Rating: 4.4 / 5

These drills worked perfectly. I had previously purchased one 6mmErbauer drill from Screwfix, but having seen the reviews here, purchased these and returned the Erbauer, which had a very short shank anyway. These drills were brilliant. I only used two and could have actually got away with one. I still have eight brand new. Used for drilling 30mm thick granite cap stones, as a pilot drill for 25mm core drilling. The fact that they have a 6mm parallel shank throughout their length is also useful. Totally recommend

Great value for money they do the job really well. I have bought much dearer cutters over the years what a waste of money.

Well what can I say absolutely fantastic drilled 10 holes with just one bit into porcelain tiles 10mm thick using water 💧 using syringe and cleaning diamond bit head every 15 seconds 😀 Definitely listening to all reviews and tips helpful getting your mileage out of just one 5 star Definitely 🌟 start of slowly keeping it on a tilt then straighten up once made an impression

It says these a for ‘dry’ use, but they buckled badly whilst drilling my porcelain slabs. When I used water to cool them they performed much better. Went from 1 hole per bit to three or four. Use water and they’re pretty good.

They work. Decent quality, decent price.

He quemado 3 brocas de tungsteno y 1 hora de trabajo, para hacer un agujero en un pavimento de piedra de granito gris. Buscando he encontrado estas brocas de diamante, y con una broca he conseguido hacer 8 agujeros de 10 mm para instalar una valla metálica en media hora ( y sigue en perfecto funcionamiento). Me parecen una brocas excelentes para este tipo de trabajo imprescindibles diría yo. Lo único es tomar algunas precauciones.- 1) Mojar la broca frecuentemente para enfriarla. 2) Como tiene un hueco en el centro, deberemos vaciarlo y sacar el trocito de granito para poder seguir taladrando, ya que de lo contrario no puede perforar, 3) limpiar periódicamente la superficie con un cepillo y el ajujero soplando con un tubito para sacar los granitos y el polvo. Siguiendo esto podremos hacer agujeros en el granito de forma operativa y relatívamente rápida.

decent quality for the price, they worked great for tile...slow speed and water

Testat. Flera olika, koremantborr. Men de här. Är totalt bäst. Vaxet ihop med hög hastighet gick jättesmidigt. Kan varmt rekommenderas! 👍

Read the dimensions… they’re tiny barely big enough for anything you gonna be doing with stone

forets utilisés pour percer du carrelage extrêmement dur. Perçage bien plus rapide qu'avec le foret spécial acheté plus de 30 euros chez Leroy Merlin, et plus de trous avec un seul foret. très satisfait
