Erbauer Diamond Tile Drill Bit 7 x 80mm is rated 3.8 out of 5 by 25.
Rated 5 out of 5 by from Excellent After reading other reviews I thought I'd give them a try... The tiles that I've been drilling into take on average an hour and a bit to get through using other well known brands, these take about ten minutes!! they are awkward when starting a hole but once you get a bite they are fantastic.

Rated 3 out of 5 by from Ok, but expensive. Had to put some blinds up in tiled bathrooms and kitchen. My normal masonry bits struggled so I bought the 7mm version of this. It was good for 12 holes but was then completely blunt so couldn't finish the job on one bit.

Rated 2 out of 5 by from Starts well but doesn't last We have used now about 9 of these, drill well and we cool the tip whilst drilling with water but about a 1/3 of the way they glaze up and even trying to drill hard stone to reverse glaze doesn't work. Center tube block and constantly requires clearing. Good but expect return trip to exchange 75% unused bits but to glazing. PS we have used diamond bits for 15 years so are not strangers to diamond drilling.

Rated 4 out of 5 by from Tilebit Drills through tiles well but can move away from Centre slightly if you don't have the guide, a bit overpriced in my opinion but all tile bits seem to be, certainly a lot quicker than using a standard drill bit.

Rated 4 out of 5 by from Diamond tile drill bit Very good tool, I think that a guide of some sort is required to get the hole started in the correct location. I made one myself but you can purchase them from screwfix

Rated 2 out of 5 by from 10 holes This drill works well for 10 holes in porcelain. I would buy again...and need to but bear in mind it will wear out. Can get expensive i guess. Im just about to buy another cos I havent found anything better.

Rated 5 out of 5 by from Pricey but works I hesitated about paying so much for one bit as I only had a shower cubicle to install. Problem!!! No drill bit I owned would even scratch the surface of the stone tiles I had so this drill bit was a must! I've been running it under the tap quite frequently not just to cool it but also clean the head as it seems to work more efficiently afterward! Yes pricey but it works well!!!

Rated 5 out of 5 by from Makes mincemeat of tough tiles I wrote off three masonry bits trying to put a hole in the porcelain tiles in my bathroom, and finally relented and got this. It went through the stone-hard tiles without flinching like a knife through butter: beautiful neat, well-defined hole, no fuss or chipped edges. I gave the "value" rating 4 stars because for an occasional DIY-er like me who only needs to make two holes for a shower rail, this is an expensive bit of kit, and the "features" rating 4 stars because (as other reviewers have noted) it needs a guide to locate it properly and stop it skipping around before it starts biting into the tile. But truth is, I'd buy it again if I needed to drill these tiles.
