What drill bits do you guys use for drilling thick porcelain tiles? Got 4 bathrooms to second fix with 10mm thick tough porcelain tiles. I’ve tried loads of different bits over the years and just don’t find they last very long.
I don't disagree with you Ben-gee, but from memory they don't tell you to clear the hole in the instructions (Which is only 2-3mm in diameter in the 6mm diamond bit and as such incredibly difficult to actually clear out). So, you can either learn the hard way (unfortunately like I did) or hope that someone might give you advice so that you don't have to.
The Rubi kit from screw fix is pretty good...don't try using the drill adaptor.. put them on the M14 thread on your grinder... start your holes at 45 degrees and don't force the bit or it will burn out. If I'm drilling more than 1 or 2 holes then I cost a set into the job to allow for
fixing wall channels, towel rails etc and the inevitable loo roll holder/mirror/ toothbrush holder/towel holder/shelves/cabinets that the customers assumes is part of the job (so cost for that too !!)
They’re great bits Craig and I use them for most things,. I have, however, come across porcelain that they just won’t touch. The worst I’ve had has been from grespania but a lot of the manufacturers seem to be going overboard on this recently. Really difficult to cut and drill, unnecessarily so as far as I can see.
