We had a bathroom refit many years ago, was well done, except we noticed only recently that rather than securing the towel radiator to the wall by using screws thru the metal spacers, they stuck the metal spacers to the wall.
So, it'll be no surprise to learn that lately the radiator came away from the wall and was only being held vertical by the in/out pipes at the bottom, so nothing could be placed on it.
Never drilled tiles before, and these tiles are 9mm Ceramic. A quick youtube search told me that a tunstgen carbide tile drill bit is required. I duely bought one from the local screwfix:-
£7.99, but I thought hell it'll do me for whatever i need in the future.
Started the first hole. By the time I was 2/3rds of the way thru, there was smoke coming out. Once I go thru the tile, i used a standard masonary bit to drill into the wall. The 2nd hole, well it took about 5 mins, and it was smoking from the start. I'm pretty sure I just burned my way thru that hole. When finished the bit was black half way down it's length and even the part of the bit that was in the makita drill was damn hot, the business end musta been seriously hot.
I think this bit is now shot.
Was my technique wrong ?, I was applying quite a bit of force , as that seemed to be needed to make any headway. Should I have just used a lot lighter force and maybe taken 10mins on each hole ? it did do the job, as i only needed to secure with two screws, and there was no skidding about the tile at the start which was great, but for a drill bit designated as "bosch expert high-performance carbide tip for long life in hard tiles" it seemed to wilt rather quickly.
I do (latterly) note that the screwfix entry says "slow drilling speed". I did use the slow speed until I had a good start and then switched to the higher speed. Maybe that's were i went wrong. I left a pretty scathing review on there, but maybe it was my technique ?
