Parfait pour percer le carrelage il faut juste vérifier le serrage du forêt régulièrement pour éviter de perdre la petite vis qui le tient. Sinon bien utilisé ce forêt fait le taf sans soucis et rend un travail propre.

We had to drill a hole in a granite counter top and this worked great. The pilot guide thing in the middle would not go through the granite, so we took it off, and no problem. We were not able to use water to cool it, so we drilled it in increments to let it cool, and that worked well.

Amazing
