365 drills

Thought I'd add a bit of info.

These were Le Piezza "Porcellanato" tiles (500mm x 330mm x 9mm). Cut the tiles to 7cm width before drilling. Drilled flat on a workmate bench using a cordless driver at "screw" speed with constant flow from a hose. The cut took about 5mins at that speed, but the bit stayed pretty much cold throughout. I need to cut a total of 6 16mm holes in these tiles hence the slow speed, but I'll happily take advice if this is an unnecessarily slow speed?

Perfect cut to run Hep2o plastic radiator pipe through. Added a pic of the drilled tiles.

PS It was the Bathroom Fitters kit I bought.

I think you can use a faster speed than that as long as you keep it cooled with water as you say.........

You are doing all the right things to get the maximum life out of the core and the most numbers of holes.

Providing you keep the core cold (max warm) you should
get the proper life span.

DONT : Heat the core. Drill too fast. Apply too much pressure.

DO: Keep the core cool. Drill at setting 1 on a hand drill. Apply gentle pressure.

If the tiles are not fixed and you can drill them outside its easier to apply a continuous water supply via a hosepipe - over a drain etc.

If the tiles are fixed (and vertical) Then holding a wet sponge under the core will cool it down plus it will collect the dust at the drill site.

Don't mind me while I bump up some of the old threads. I wont be doing this much more. Just the last few in the Tile Drilling forum - How to Drill Porcelain Tiles. Just one of the many tiling advice forums.
