TITGGI Professional Masonry Drill Bit Set (10PCS) for Glass/Brick/Plastic/Cement/Wood/Tile/Etc, Industrial Strength Carbide Drill Bit Tip, 1/8"-1/2"

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.

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.

Went through concrete like butter

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.

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.

It was what was promised and came with extra bits.
