Erbauer Diamond Tile Drill Bit 16.5 x 8mm is rated 3.6 out of 5 by 8.
Rated 4 out of 5 by from Diamond Drill Bit Effective at cutting porcelain and ceramic tiles. Very expensive for what it is though, I'd have at least expected it to come in a plastic tube to aid storage instead of just a piece of cardboard. Would be good if Erbauer produced a box to house the drill bit guide and the drill bits to protect my investment.

Rated 2 out of 5 by from Great while it works Clean and easy holes in ceramic and porcelain tiles. My gripe is the use of the term long life - the first one managed two holes in porcelain and two in ceramic, the second got halfway through the third hole in ceramic, after which the end was completely smooth and no use. I'm loathed to buy a third, but I have more tiles to drill.

Rated 5 out of 5 by from Trade use Used these before, but in a smaller size. This is the first time with this size and it worked perfectly. I have the guide for drilling into tiles with, but if the tiles are bumpy it's not going to work, so I did the holes freehand on a slow speed cordless drill/driver, cutting at angle first then lifting it straight as it cut in. Don't expect these to do lost of holes in porcelain tiles, it wont, you will get about 3 to 4 holes before it's no longer cuts. If you do use it on porcelain tiles, keep dipping it into candle wax so it helps it cut.

Rated 2 out of 5 by from Very poor life Cut two holes, totally blunt by third hole. So seems poor value.

Rated 5 out of 5 by from Fantastic Bought a few cheaper alternatives online and useless, this did the job with no question with plenty of life for next time.

Rated 2 out of 5 by from poor quality Fine if you're cutting ceramic but don't bother if it's porcelain. Cut two holes and gave up on the third. Totally blunt. If you have anything more serious to do, invest in a better bit......or buy ceramic tiles!

Rated 4 out of 5 by from Tidy clearance holes-15mm pipe When used with the Erbauer drill guide (also available at Screwfix) this diamond drill produces very good results. Needed holes cutting in ceramic tiles in the bathroom to provide clearance for 15mm copper pipe coming back through stud walls and this item did a brilliant job. Good clean holes (used cordless combi drill), no wandering (because of the guide) and most importantly no broken tiles so NO WASTAGE. No signs of wear, but then I have only cut 8 holes with it and only in Ceramic so can't comment (yet) on the performance on Porcelain tiles.
