Drilling a heavy stone resin shower tray using diamond bit

[what]

In need to drill 2x 6mm holes in to accommodate plastic rawl plug and screws which will hold metal blocks to support frame-less glass shower panels. I'm thinking of using a wax cored diamond bit - is that the safest way to go ?

i used the bosch multi purpose bit. started with a smaller bit then moved up to a 6mm

And invalidated the warranty on the tray.... I'm not drilling holes in expensive trays that are all tiled in. I use Clearfix and stick those blocks down.

Where do you get clearfix?

Won't the adhesive fail and peel off or what ever after a few years long since the plumber has gone?

Some manufacturers shower doors. Especially, the frameless ones, need a positive fixing into the tray.
On a stone resin tray a normal masonry bit will be fine. Put a spot of silicone over the wall plug before screwing down. Whichever way you "might" invalidate the guarantee of the tray if you drill it, or invalidate the screen warranty, if you don't fasten it fully down .
Personally I would fix the screen properly.

I had a proper look at the instructions with my glasses on. The instructions are purely diagrammatic and it appears that there are two alternatives one using rawl plugs for going into a wet room type of floor I think and one which uses a a thin 2.8mm drill bit which the uses a self tapping screw for fitting on a shower tray. The shower and base where supplied together so i am assuming I can use latter method in my situation.
