Concrete Drill Bit Set - Masonry Drill Bit, Professional Masonry Drill Bit Set (10PCS) for Concrete/Glass/Brick/Cement/Tile/Wood/Etc, Industrial Strength Carbide Drill Bits Tip, 5/32"-1/2" by TITGGI

My son sprayed water on the tip as I drilled into a solid red brick wall for hanging shutters and it was easy and quick! Great product great advice and the drill bits are in a really nice holder to keep them organized by size. I read reviews and those that had issues is simply because they drilled dry into concrete or brick. The tip get really hot and can break unless you keep it wet! Again just keep it wet while drilling. Simple

hellowe got tricked into buying a set of a drill, phillips head driver for a drill and a few concrete screws... an all in one package. but after one hole in a concete block, it would not drill deeper than 1/2 inch. the tip was too dull. so, luckily i had a separate concrete drill and it drilled 5 holes before it, too stopped making deeper holes.now, i purchased a set of concrete drills and the one that i used drilled 6 holes with the same drill and i could probably use it again for more holes. this set is specifically made for concrete, but can be used for other products. so, if the drill bit gets dull for concrete, there is another one of the same size included in the pack.an excellent product and saved me a lot of time not having to go to the crowded local store to get another concrete drill.thanks for a great product. nice case that slides open, too.

Worked well and stood up to the task

The bits work best if you use water or oil to cool the bit while cutting. Note: the words "for... tile" is in the website description; tile is not included in the provided instructions. When the bit becomes over heated, it cuts nothing and the life of the bit drops significantly. I normally drill for 8 to 10 seconds (smoke/steam is visible) and cool (dunk) the bit in water for 2 to 3 seconds. I use a rubber grommet (like a faucet washer) to minimize the impact of the drill on the tile when breaking through/completing the hole (the amount of pressure applied as I drill is high enough that the drill chuck will hit the surface of the tile before I can react, i.e. pull the bit back). The rubber piece has a hole that fits over the shaft end (not the cutting end) of 1/4 inch bit.

These did a great job drilling into hard brick. I didn't have a helper to spray water onto the drill bit, so I just stopped every 15 seconds or so and dipped it into water to cool it down. Excellent value for money.

They dull very fast unless you have a ton of patience. Expect a much longer time to drill each hole if you want to extend their life past 4 or 5 uses. Make sure to constantly cool them, much more than you would normally. For the price, they’re fine to use for one job and then throw them away, but that’s all.

Need to drill through some brickwork and didn't have any masonry bits, so after looking around I chose these. They worked prefect and I got my project done in no time and without any issues.The seller was helpful and reached out after my purchase and gave some more helpful suggestions and offered any assistance if necessary which I appreciate.

These drill a lot faster and with less effort than the standard masonry drill bits. Great purchase

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

son brocas excelentes las recomiendo muy ampliamente

Aun no las pruebo pero a simple vista no se ven tan afiladas y el acero se ve de baja calidad. Mi opinión es a pura vista y sin haberlas ocupado, pero creo que les pongo un 7.5 de 10
