Erbauer Diamond Tile Drill Bit 7 x 80mm is rated 3.8 out of 5 by 22.
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.

Rated 5 out of 5 by from Great drill bit and best value Trying to drill hard porcelain tiles was a real struggle with conventional tile drills. I wrote off most of my other tile/glass drills in the process. When I eventually brought this I was amazed that it works very effortlessly and can take the heat from high speed drilling. No problem to clean when they get clogged either. I will be buying more of these drills.

Rated 5 out of 5 by from Expensive but worth it Last time I did a bathroom, I used porcelain tiles and had a nightmare drilling any holes. This time I went for ceramic tiles thinking my life would be easier. Not the case!! I tired a variety of things (decent masonry bits, the Erbauer 3 pack tile and glass drills, the more expensive Marcrist tile drill bit) and none of them touched it my tiles. Bought this drill based on other peoples reviews and really glad I did. Had a few issues starting the holes because the bit skips about on the surface of the tiles. Got a piece of timber about 10mm thick, drilled a 7mm hole and used that to hold the drill in position. Then removed the wood once the hole was started. Spin the drill fast... It's works a lot better because it clears the dust out of itself. And I stopped about half way through each hole to dip it in water. The bit got really hot. Took about 2 minutes to drill each hole so be patient with it but it does work. I drilled about 20 holes and the bit was still as sharp as when I started.

Rated 5 out of 5 by from Perfect tile drill bit I have previously used cheaper wet drill bits which can be quite messy and difficult to keep cool. With this drill bit which I have been using on tough 12 mm porcelain tiles for a full bathroom has been brilliant. No need to cool with water and it goes through far easier so for me it has saved me lots of time and a lot cleaner and still like new. Other bits have been tired and blunt after a few holes but this is second to none. It's much more cost efficient than buying the cheaper ones, you get what you pay for. QUALITY
