Tips To Drill Tiles In Toilet

[Eurypylus 0]

Use a Tile/Glass drill bit in drill mode and once u have drilled thru the tile, then switch to a masonary drill bit in hammer mode to deepen the hole to the desired depth to fit your wall plug. Using the tile bit all the way is more difficult and will spoil the bit..

I've tried using the triangle bit for tiles/glass. Have been drilling 1/2 an hour, not even 1/2 way thru the tiles ...>_<...

Yeah i had the same problem with my kitchen tile! Hard thick tile (7mm?), which was different from my bathroom tile. Anyway the triangle tile bit is not for all tiles, especially hard tiles like quarry tiles (don't ask me what that is cause i also don't know) For my case, after the initial try with the tile bit (which went in about 1-2mm only), i switched to a normal masonary bit in hammer mode all the way to the desired depth with no cracking. But generally for difficult drilling, there are 2 things u need to take note of:

1) Make sure your drill is set in the right direction (bit should be spinning clockwise). There've been times where i forgot to switch back the direction after using the drill for unscrewing. Most drill bits are designed for 1 direction only (clockwise) so this is very important!

2) A new drill bit helps as the old one might be worn out.

1/2 hour is way too long so something is wrong. So u can try again in perhaps the following order:

1) Use the Tile bit in drill mode for the initial drilling (to maybe about 2-3mm, then switch to..)

2) Masonary bit in drill mode (see if it goes in. If not..)

3) Masonary bit in hammer mode (start slowly and watch out for cracking)

Do try in the above order and see if its effective. Of course as u move down the list the risk of cracking gets higher. As long as u use the tile bit for the initial puncture and then switch to a masonary bit, should be ok. I've heard of hard walls that need more powerful drills but for tiles the drill itself shouldn't be a problem!

Thanks for the advise, after trying 1/2 an hour with the brand new tile bit(I cool it off with water at 2-3 min interval), I finally gave up and us the mansonary bit at drill mode(again cool with water at 2-3 min interval), then finally masonary bit at hammer mode(slow speed). The tile surface did chip off, luckily for me, my hanger fitter manage to cover the chip. Total time spend = 45 - 1 hour for 2 hole :-(

I've seen the door maker using a special bit with hollow in the center for drilling floor tiles, it seems to work well for them. Then I did not manage to find one in the market myself.
