Drilling in Stone Resin Shower Tray

[rules&rulers]

Done that before for a 10mm glass enclosure its to give a little extra support/stop movement of the heavy glass panels.
Started off with a 3mm masonry drill,then 4mm,then 5mm and finally 6mm vacuum out any dust in between drilling and use brand new drill bits on percussion only.Take your time.
The rawl plug expansion is very minal so it just acts as a lug to stop movement.
Easy.

It's not a matter of 'how' to drill the tray... I have an array of diamond cores and point bits for all types of surfaces!
It's more about 'not' drilling the tray!

With silicone along the bottom of the glazing there is just no need.
