Rated 5 out of 5Â by TF11 Works well, in my limited expe
After only making a 2mm deep 'saucer' after 30 mins through a 9mm tile using a tungsten bit, and faced with needing to drill a total of 4 holes, decided that I needed to spend some cash on fancy technology.
Bought this (v) expensive one ( 6mm ) and a cheaper 7 mm one of another brand, and used this to do donkey work first hole.
Preformed almost effortlessly, with the waggle techinique, after first using the tungsen bit to give me a centre punch start. After 4 holes looked like had lots of life left in it.

Good quality drill bit that makes little work on hard porcelean tiles, i start with 6mm then open with bosch multi construction bits if need bigger hole. Reduces alot of time but lost my drill bit so cant comment on its longivity. worth it if you get 50 to 100 holes out of it though. macrist are great at making tools for tiles

I am cutting 10mm porcelain tiles and this drill is the only one which will cut more than two holes before dying.
I don't get the 30 odd as specified but I do get 9-10 which is very good in these tiles. Masonary bits and pointy tile drills won't even marks the tiles I have.

Rated 5 out of 5Â by ITJohn Worth paying extra
I've tried a few diamond drill bits to drill holes in porcelain tiles and it is worth paying the extra if you work out how many holes it has cut. The slightly cheaper brand sold only managed 8 holes before the bit was worn out. This one has managed over 15 holes and still has plenty more in it. A bit of a learning curve drilling porcelain it is much harder than ceramic so do not expect holes to cut through under 5 mins with a drill running at 2000 rpm. Gently does it, a hole guide with suction highly recommended (no slip when starting the cut), a water cooling system highly recommended (allows you to cool the tip for longer life). Don't apply too much pressure, allow the drill bit to do the work and be patient. Finally, tell the wife to buy ceramic wall tiles next time (floor should be porcelain though). Even my tiler said I told you not to buy porcelain wall tiles they are too tough for normal tile drill bits.
