TITGGI Concrete Drill Bit & Masonry Drill Bit Set, Professional Drill Bit Set (5PCS) for Glass/Brick/Plastic/Cement/Wood/Tile/Etc, Industrial Strength Carbide Drill Bit Tip, 1/4"-1/2" by TITGGI

These work very well.. truly high speed cutting. Nice little storage kit, decent length, easy to install, shows no sign of future bending, and accuracy is on the nose. Nice job although they feel like it will get dull after about 10-20 uses, I'll update if necessary.

These were exactly what I needed to drill holes in tiles to make Christmas ornaments. They worked really well.

These bits held up pretty well overall - one did break, but the rest got the job done. Used them for a small masonry project and they performed better than expected for the price. Good value if you just need a reliable set for occasional use

I purchased these drill bits to drill through homemade ceramic pieces to create drainage holes for plants. This set drills easily through ceramic pieces where previously made drainage holes have been filled with glaze (essentially glass) to clear out the holes and even drills straight through glazed ceramic where I want new holes without damaging the whole piece. Highly recommend for your pottery toolkit. Probably works well for home improvement stuff.

Drilled 6 holes through bathroom ceramic tiles, and these drill bits did an outstanding job. Drill bits were as sharp as new when finished drilling. Drill bits come in a very nice storage case, which is another nice bonus.

Best masonry bits ever. Long lasting

I recently purchased the masonry drill bit set with high hopes, given the positive reviews and reasonable price point. While my overall experience has been somewhat satisfactory, there are a few notable areas that fall short of expectations. Firstly, the packaging was robust and secure, ensuring that the drill bits arrived in pristine condition. The bits themselves appeared well-crafted, with a solid build that inspired confidence. The range of sizes included in the set is commendable, providing ample versatility for various drilling tasks. In practical use, however, the performance of these drill bits has been a mixed bag. On the positive side, the bits managed to penetrate standard brick and concrete surfaces with relative ease. For light-duty tasks, they performed adequately, maintaining a sharp edge over multiple uses. Unfortunately, when tackling more demanding materials such as reinforced concrete, the limitations of these bits became apparent. Despite following best practices for masonry drilling – including using a hammer drill and applying steady pressure – the bits showed signs of wear more quickly than anticipated. The cutting edges dulled after just a few intensive drilling sessions, leading to decreased efficiency and increased effort on my part. Another point of concern is the heat dissipation. During prolonged use, the bits tended to overheat, which likely contributed to their premature wear. Frequent pauses were necessary to allow the bits to cool down, disrupting the workflow and adding to the overall time required to complete projects.

These drill bits have excellent drill performance and drillability — they cut through concrete like butter. I used water while drilling to manage dust and heat, and the cut quality was clean and smooth while creating a ¼-inch hole about 2–3 inches deep. The fit in my drill was perfect with no wobble, and I appreciated having multiple drill bit sizes included, which made the set very practical for different jobs. The included case also has good storage capacity, keeping the bits organized and easy to access. The only reason I docked one star is durability. After a single use, the bit showed noticeable wear, which makes me cautious about long-term use. That said, given the price point, this feels like a fair trade-off. Overall, great performance and value for occasional concrete drilling — just not ideal for heavy, repeated use.

I don't really understand where such a high rating for these drill bits comes from. My experience: One drill bit barely lasts for one hole. After that, the drill bit tip completely breaks down. Terrible quality.

Went through concrete like butter

It was what was promised and came with extra bits.

Estás brocas me dejan algunas dudas por lo siguiente. Las compré específicamente para taladrar en un azulejo del baño, para colocar una repisa. Me preparé bien, con un bote de agua al cual le hice un orificio en la tapa para enfriar la broca con agua al tiempo que taladraba. Empecé con el primer orificio, el taladro con una mano y el agua con la otra. Se hizo el orificio correctamente pero cuando saqué la broca me di cuenta de que estaba totalmente despuntada. La punta en forma de flecha ya no estaba ahí. Por lo mismo, era imposible seguir usándola. Así que tomé otra, un poco resignado a qué iba a utilizar una por perforación. Hice el segundo orificio siguiendo exactamente el mismo proceso y la broca salió perfectamente, sin daño alguno. Hice otros dos orificios en el azulejo sin problemas, la broca en buen estado. Después de eso hice otros dos orificios en la pared (no en azulejo) y todo bien. Me llama la atención que la primer broca duró una perforación mientras que la segunda sigue en buen estado después de varias perforaciones. Me parece que la calidad no era la misma, porque yo no hice nada diferente. Ahora me pregunto, cuánto durarán las otras. Pero al final me sirvieron para lo que quería. Adjunto fotos de las brocas y los orificios.

Son de buen material, no las he usado mucho pero espero que su patente resistencia sea real
