Rated 5 out of 5 by from Best tile bit Best tile bit I have used, cut through the tile like a hot knife through butter

Rated 1 out of 5 by from 8 Holes and lost edge Saw this had a 1 year guarantee and would drill the toughest tiles. Drilled on full speed as recommended, as you have to start at an angle to get a bite it is useless once to corner has gone. Managed 8 holes but then edge totally gone and could not get a bite. Will be returning for a refund as per guarantee. Local builders merchant had one so bought it and its still good after over 20 holes - same price as Screwfix

Rated 4 out of 5 by from A time saver! After burning out a so called diamond bit from else where, I walked up to my local screwfix and bought this little beauty. I drilled holes in my new porcelain tiled bathroom floor in order to re fix the WC. It will come in for my next few projects as I'm sure it will retain it's sharpness.

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.
