Buena calidad del producto. Debe considerar que para perforar no es útil pero para debastar si que lo es. Si desea perforar azulejo lo recomendable son las circulares con punta de diamante y esta, para Dremel, la podría utilizar para iniciar una guia ya que, por lo menos yo, no pude perforar completamente una baldosa, aunque un pequeño orificio que sirva como guía, si.

Good for cutting odd shapes but took some attempts to master.Cuts wall tiles well

Needed to enlarge a plumbing cutout in shower so that I could get access to service the shower valve. (Genius tile installer from 20 years ago left virtually no room). This bit did the trick, and I'm sure it could cut a several more times before it wears out.The hole shown in the photo was made larger by the bit. It did the trick.

タイル切断する用途ではないかと思います。少しずつ削って成形していく感じで、ビットの直径とほぼ同じ幅が削られる点を考慮して使用することになりました。

High quality tool. This little bit has saved me many times, to correct all those little mistakes that I always make. I can use it to initial fab or on-site, or in situ, as I am trying to get something to fit, that doesn't of course, a quick little trim and in it goes, in 5 minutes vs 5 hours of refitting a new piece. Easy to use, don't even have to drill a pilot hole for it to start it off, but it is quicker to do so. Once in, can go in any directly pretty quickly. Its is noisy and messy. Actually stays very sharp while using it on almost everything except aerospace metals. Wish I got this much sooner. It paid for itself many many many times over. Get a couple of them, in different tools boxes, but put them into a container of some type. I use a clear plastic kitchen veggie Tupperware thingy, so I can see what's in there. Much harder to loose track of it in the larger plastic container. I can't live without this one now.
