Bosch Expert Diamond Tile Drill Bit 5mm is rated 1.9 out of 5 by 14.
Rated 1 out of 5 by from Very Poor Very poor by Bosch which are normally excellent. Had some hard bathroom tiles, only managed to drill 3 holes before the tip came out of the shank. The holes took over an hour, I kept the bit cool by drilling slowly in short bursts (the only way you can use these bits). Took back and got an exchange thinking it was a faulty bit and bought 2 more, but it must be the bits as I have had the same issue on all the other 3. Keeping them cool with water doesn’t help either. It took 2 hours to drill 6 holes, the tip has come off one bit, the other is totally blunt and the third is getting blunt. Wouldn’t recommend these it you have hard tiles, am going to try something else as these are useless.

Rated 1 out of 5 by from Waste of time and money Very disappointed with this drill bit. I managed to do only 2 holes before the head completely melted. Expected better from Bosch.

Rated 1 out of 5 by from Not even one hole! I tried to drill a few holes in my new bathroom tiles to fit a new shower cubicle, toilet and sink. Blunted the bit before it had even drilled one hole. Unfortunately, I brought a second bit as that: A. blunted just as quick as the first one (I actually managed to get one hole done!) and B. Wasted my time and money Disappointed would be an understatement. I expected more from a Bosch product........ :(

Rated 1 out of 5 by from Failed Wish I had read the reviews before I bought this. Failed after 2 holes. I could have bought 3 cheaper ones and finished the job.

Rated 1 out of 5 by from Good for 1 hole. Really disappointed with this drill bit. Managed 1 hole before it went blunt. Lucky enough I bought a Erbauer set (cheaper) and the 5mm bit out- performed this Bosch one. Gonna ask for my money back.
