Rated 4 out of 5 by from Done the job Used to drill holes in porcelain tiles 2 holes so far worked ok. 2 holes left to drill so see how it copes with them i thought it was a bit expensive but it done the job

Rated 4 out of 5 by from Expensive but worth it Bought this and a larger 44 and they both cut my 600x600 porcelain tiles extremely neatly with no breakage or chipping of the edges.

Rated 4 out of 5 by from Good value tile drill Inexpensive drill bit which cuts holes in porcelain tiles. Works well if used as shown on youtube. Used battery drill, chuck speed possibly a bit slow. Have cut 2 holes well cannot comment on how long bit will last but does not look like much wear. Good bit of kit if a DIY tiler.

Rated 4 out of 5 by from Drill bit Dry cut, clean finish on the edges, no problems 'gripping' the tile to get started. Can't compare with any others as this is the first time I've done any tiling. Expensive, especially when a tenner cheaper if you buy two; but they only had one in stock and I needed it there and then. Ordered. Collected. Holes cut. Job done

Rated 5 out of 5 by from Top performer by far Used numerous cutters like this - Rubi and Marcrist and this one lasts much longer with no need for water to cool it down, and believe me I drill a lot of holes in porceline tiles! 10/10

Rated 5 out of 5 by from You get what you pay for. Pricy but worth it. Cut through very hard floor tiles with ease, leaving neat holes for pipes.

Rated 4 out of 5 by from Great on porcelain Didn't realise how hard porcelain tiles were! Having totally re done the bathroom and contemplating fitting everything back in the number of holes needing to be drilled stacks up. This drill bit has far out shone others I bought. It didn't skid around on the surface like some others when started in slow speed and angling v slightly upwards to get a key in before then going straight. It cut through the tiles very easily relatively quickly without overheating.
