Rated 4 out of 5 by from Pilot drill for porcelin tiles Used this as pilot drill before using "core" type drill to drill holes in porcelain tiles. Use this to break surface glaze on tile and to provide hole diameter large enough for core drill to engage without drifting over tile surface. Used water spray ( old Mr Muscle cleaner spray bottle) to aid cooling during drilling. Drilled 12 holes so far and still going strong.

Rated 1 out of 5 by from Not so expert diamond drill Advertised as cutting porcelain tiles, other peoples reviews say how great this bit was?? I wanted to cut 4 x 6mm holes, after 2 hours only managed 1.5 holes. drill set at 500rpm, non hammer action etc. Drill packaging states no coolant required... drill bit getting to hot so cooled...still stopped cutting after 1.5 holes ...totally blunt! This bit in my opinion, will NOT cut porcelain Tiles!

does this drill bit fit into any drill?

Asked by: adam2222
Hi adam2222. We can not advise that this would fit ANY drill, as many drills have different chucks and clamping methods. However, if the drill in question uses an SDS chuck, then it is safe to assume that this drill bit will fit.

Would I need a 5mm or 6mm drill bit with 3.5 screws (not sure size of wall plug but its 30mm in length)?

Asked by: Tim2016
Hi Tim2016, firstly you would need to know the size of wall plug then go half a mill (mm) of the wall plug for e.g 8mm plug = 7.5mm drill bit diameter. Then the working length must be longer than 30mm.

should this bit be used at slow speed for drilling ceramic bathroom tile

Asked by: paulxyz
Hi paulxyz. Do start of at a slow speed, we also recommend oil to lubricate the drill bit.
