I have had all kinds of problems cutting hole in tile, ceramic pots. These bits have great ability to start at a 45 degree angle and c gain traction transferring seemingly to 90 degrees they cut without wobble or cracking the tile or a pot. The holes are almost perfectly round.I think the largest is 20 millimeters. I order again I think I want larger bits.I

My son had the hole in the floor enlarged in a matter of minutes. Fit right in our Ryobi drill.

They did get the job done... But, thats because I only needed 4 holes and was willing to ruin 3 bits in order to do so. They may work on something thinner and/or softer than 1" granite countertops, but they didn't work well on mine. I do not recommend - especially if you want to use them more than once.

Ehh.. these bits can drill a hole but they wear out very quickly. Or the tip breaks off. For the low cost this was expected.

These are great worked worked exactly as described for porcelain tile. I bought a couple extra because the stuff I purchased from another source worked so poorly, but was able to finish the job using only one of these bits.

Je ne comprends pas les avis négatifs qui disent que ça casse facilement. Alors oui, même si il y a une sorte de graisse dedans, faut quand même mouiller en continue le carrelage et faire des poses de temps en temps pour ne pas que ça chauffe trop, et ce afin de ne pas abîmer les forêts trop rapidement, mais je témoigne que j'ai pu percer toute ma salle de bain avec sans aucun problème.

Ho eseguito dei fori su mattonelle in gres porcellanato per fissare il box doccia, consiglio di mettere uno strato di nastro carta sulla mattonella nel punto da forare, all'inizio tenere leggermente inclinato il trapano e bagnare bene la punta.
