Realistically on glazed Porcelain tiles you will get average 8 holes drilled before it starts to wear out. Ceramic you would get much much more. Tried using other types and makes of tile drill but when you drill a hole using this in 20secs you'll not want to waste time going back to anything else.
The Erbauer drill guide very much worth the money too. Definitely recommend.

Rated 3 out of 5Â by Smudgersplace Buy a Marcrist instead
Put your money toward a Marcrist if you plan on drilling really hard Porcelain.
I spent nearly two hours drilling half a dozen holes in the hardest 10mm porcelain tiles with two of these bits. The first had already done a bathroom but the second was new out the packet.
Had another four to drill and gave up on this bit and went and spent the money on a Marcrist alternative.
What a difference!! drilled 4 x 6mm holes in about 10 minutes. Should have bought the more expensive bit in the first place instead of being tight and opting for cheap and cheerful. False economy.

Rated 4 out of 5Â by Hamore Erbauer diamod tile drill bit
Needed to fit shower screen 4x screw holes and a riser rail 4x screw holes in class 5 porcelain tiles which are very tough, nearly impossible to drill with standard masonry drills. These erbauer drill bits do the job very well, they dont need water cooling as there self cooling. Done job in 15 minutes and the bit still as new, would definately buy again.

Rated 2 out of 5Â by ITJohn Disappointed
Drilling through 9mm thick porcelain tiles this drill bit struggled, the first took about 10 minutes, the subsequent were taking slightly longer until the 8th hole it took nearly 1 hour to drill through. Checked the drill bit and it was completely worn. The bit was being cooled with a tile cooling system and only light pressure applied during drilling. Disappointed with the cost vs performance/reliablity of this drill bit at Â£2.13 per hole. Used a more expensive drill bit which is expense I did not expect and this is performing much better than this Erbauer diamond drill bit.
