Rated 4 out of 5Â by Shedking Better than the rest
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.

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.

Having previously purchased a BOSCH bit which was useless for drilling tiles, I purchased this item which has so far completed 20 holes without showing any wear. I have cooled the bit during each hole which is supposedly not required but it is helpful. The only fault is that it takes a steady hand to start the hole but this would be the same with any make.

These aren't cheap but they are definitely worth it, I managed to drill around 50 holes with the last one.
You can use without the guide but it can wander a bit which can be an issue
