NS2000 4 pc. Natural Stone Tile Set

Had to drill four 3/16ths" holes thru my brand new marble shower to mount the slide bar for the hand held wand. Took 5-10 minutes per hole at super slow speed with my Makita 1/2 inch drill. Cutting dry actually works better than dipping the bit in water. Bit does not heat up while using. After the two first holes I switched to a new bit. No wandering tip on these bits and they did not chip or crack any of the marble tiles. No chip out, perfect holes. I am completely satisfied with the bosch bits for cutting thru marble stone and the underlying thinset.

Quality tool

I used the BOSCH Bits for drilling through ceramic tiles, and they worked well overall. The carbide-tipped design made drilling through stone smooth and efficient. However, I found that the bits didn't hold up as well when used on porcelain tile. After just two uses, I noticed some wear. They’re great for natural stone, but if you're working with porcelain tile, I’d recommend using a different set or taking extra care.

Good bits for ceramics

I used these to drill drain holes in bowls in order to use them as flower pots. The bits worked great. They fit my dril lwithout any problem and are holding up very well. I have since used them for several other projects. The price was a value for me. I would recommend.

I used these tips to make several holes in my bathroom tile for my shower door project. I made a couple of holes before the tips gave up. I don't know if I used the right tip for making holes on ceramic/porcelain tile but these didn't last long.

I though it would be a good idea to repurpose some old bedframes. I did not realize that they are hardened spring steel. Literally recycled railroad rails. I quickly dulled some very good bits. Am obscure forum recommended using a carbide bit made for natural stone. I made 4 holes 3/16 deep and could have done a few more.

Without question, the worst bits I have ever used. It’s laughable these are advertised as suitable for drilling ceramic tile... it won’t even START to drill. Wet or dry makes no difference. No one can say doing this work is anything that would approximate enjoyable, however, trying to use these things adds a whole new dimension of frustration and misery. I know your asking, so here’s the answer.... I ended up using diamond hole drills that I bought on Amazon forever ago and forgot about. CHEAP ones I bought in a lightning deal for no particular reason. They went through in under a minute. Not sure where the 5stars are coming from, must not be the same bits I got.

Great drill bits

Very pleased with these bits , i only used on tiles but worked as advertised .

Qualidade excelente. Já usei e perfura muito bem. Só achei as brocas muito curtas. Não me atentei às medidas antes de comprar, mas, pra furos razos são perfeitas! Recomendo!

Muy buenas brocas Las usé para perforar azulejo cerámico y lo hizo muy fácil y rápido Recomendables 100%

Biught these to drill holes into bathroom tiles for a mirror cabinet. They performed very well and made easy work of the job.
