TITGGI Concrete Drill Bit & Masonry Drill Bit Set, Professional Drill Bit Set (6PCS) for Glass/Brick/Plastic/Cement/Wood/Tile/Etc, Industrial Strength Carbide Drill Bit Tip, 1/4"-1/2"

Pleased with the quality. It did what it’s supposed to do. I used my regular Dewalt drill to drill a hole into concrete. I DRILLED FAIRLY SLOWLY AS TO NOT OVERHEAT THE BIT. AND LET IT COOL BETWEEN HOLES.

These are amazing. Slides thru brick wall like butter!

Product is good value for the money.

The bits worked rather well. I have drill into cement with them, with no issues. Just remember DO NOT use your drills hammer function, just normal and go slow. I also used them on tile to install hand rails for a client. Just make sure you keep a spray bottle with some water in it and spray the area you are drilling, also no hammer function and again low speed. I recommend these drill bits, and would gladly buy them again if needed.

Only drilled four holes so far, seemed to work as advertised. The price is definitely right. Durability undetermined at this point.

Works quickly and cleanly when drilling ceramic pots. Use water while drilling on a fast speed and it works perfectly. The bit did not seem damaged even though it gets pretty hot. I like this drill set and am happy with my purchase.

It was my first time drilling holes in concrete to install a doorbell. It worked well and held up for the job!
