Sometimes you need a bespoke big hole drilled into a very hard porcelain tile or an odd shape. Porsablade gives you a more accurate cut than standard diamond wheels which can not be controlled so well. If you need to drill VERY HARD tiles then PORSABLADE can be used in a standard jig saw or jigsaw. Highly durable and extremly moveable. At 365-drills we produce the PORSADRILL and the PORSABLADE brands so that you have total control drilling holes into porcelain tiles.
