Erbauer Diamond Tile Drill Bit 30 x 8mm is rated 3.9 out of 5 by 17.
Rated 4 out of 5 by from Good when used wet Had to take the first one back as i used it dry as per the package instructions, and it went blunt after cutting one hole. Other reviews for the smaller sizes mentioned this but not for this size so wasn't aware. Screwfix exchanged it swiftly (thank you to Ringwood branch - always great service) and the exchanged one did 4 holes straight off when kept cool with water. The first was rubbish on second holes and cracked tiles (I assume through the heat) so would recommend this product but use wet. It is pricey but cut through thick ceramic floor tiles in a few minutes per hole. Have scored 1 for reliability as I can't comment after 1 day of use. Why are we asked this just after purchase?

Rated 3 out of 5 by from SO GOOD I BOUGHT IT TWICE This is a great bit if you accept it will only drill a limited number of holes before you need a replacement. Bought the first one last year to fit 12 x 30mm LED lights in the bathroom tiles at home. Tried the same thing this year while fitting tiles in another bathroom with the same bit, but started breaking every tile after 4 successful cuts. Examined the bit and noticed that it was wore down/ glazed on one side. Bought a replacement and it cut 6 tiles in a row without breaking any. I used a block of wood with a 30mm diameter hole cut out as a guide, clamped (not too tightly!) on to a workmate tool bench. A great cutter, but, in my experience, don't expect any more than 20 holes per bit.

Rated 4 out of 5 by from Good drill Bought this today to drill pipework holes in porcelain tiles, they cut well as nothing else would touch my tough tiles, but.... ...I had to use a small angle grinder to roughly mark the outside of hole in order to start it! As it has no pilot to guide it, just slid around even at slow speed.

Rated 5 out of 5 by from Decent cutter Used to cut holes for pipe work, cut tiles easily. Good finish to hole, no skidding off of the glaze when started at a lowiish speed.

Rated 4 out of 5 by from Excellent tile drill This made drilling porcelain tiles a doddle! I thought it was a bit pricey but I couldn't have finished the bathroom floor without it. Superb service as usual at Ellesmere Port branch.

Rated 5 out of 5 by from At Last! A drill bit that performs on the toughest of tiles. Tried all sorts in the past. When I read it was self cooling, self Sharpening, no water necessary, high speed, I was a bit sceptical. It 100% delivers. Someone posted that it's a shame it's a bit pricey, but it's cheaper than most other high quality drill bits, and if it lasts 4 times longer than the cheaper versions?

Rated 5 out of 5 by from Brilliant drill bit Had to buy this item as I was going through tile drill bits and masonry bits quicker than I could change them trying to go through thick porcelain tiles, bought this and within 5 min both holes were drilled, nice and clean and the bit is ready to go again. I did buy the hole guide as the bit if prone to slipping without it, never the less brilliant product. All the staff in my local branch(altrincham) are brilliant and easy to deal with.
