Erbauer Diamond Tile Drill Bit 8mm
The drill bit does not melt at high speeds like others do.
It does not need water.
Debris can be tapped off easily and have used it on ceramic tiles and still going strong after 10 holes. Other s lasted 2-3 holes before going blunt/melting.

Just the job
This drill bit cut through 12 mmm porcelain tiles like a hot knife thorugh butter and was as good on the 20th hole as for the first. Looks like I just took it out of the packet.

Cut two holes to secure toilet in no time.
Since it has no point, I started by holding the drill bit on its edge, then gradually turned the drill up vertically.
Having only cut two holes, I can't fully comment on durability, but the bit looks unused after cutting through 10mm thick porcelain floor tiles.
Although this is a very expensive bit, it's not a throw-away one use bit.
I chose this bit over the Dewalt and the silly cheap bits based on the poor reviews. Pay for what you get at the end of the day.

Excellent tile drill
Before buying this drill I bought the dewalt diamond tipped drill bit which took 30 mins to drill a single hole in grade 5 porcelain tiles, and required continuous water cooling. The Erbauer was night and day different, straight through the tile within 3 mins and without the need of water spray, I drilled several more holes and its still like new.
