Our diamond cores are the ideal product to put holes into mosaics.
They will drill perfect holes into glass (including mosaic glass) fitted or unfitted, grouted or ungrouted.
This kit contains a mix of service pipe holesaws and rawl plug 6mm & 8mm tike drill bits.
The way to use them is to make sure you push down on the yellow template (supplied)
Excuse the fact these are swimming pool mosaics. And grouted.
The technique is the same on your mosaics even in ungrouted (IE loose on the backing sheet)
Just lay the backing sheet and tiles down on a firm surface. Then push down on the drill-plate and it will lock all the loose tiles together so that you can start to drill the holes.
In the shot above you can see how easy it is to drill over the grout lines and deal with multiple
tile squares. You will be able to take out sections of glass
tile with ease.
The main thing to remember is that these are NOT actually drills ! (so I dont know why we call them drill bits) No these are actually GRINDERS. What they do to glass is actually grind it into dust slowly but carefully by removing or eroding the glass mm by mm. Thats why you get a chip free clean result every time.
One bonus is that you have total control over the speed of your own drill so can take things nice and slowly until you are confident
Porsadrill cores are used with your own battery hand drill
If in doubt have a little practice first but its a fairly intuitive process. You'll get it right !
