Nightmare drilling into porcelain

[ashtonjay]

As i mentioned in a previous post i was struggling to drill some porcelain tiles so i bought that kit from 365-Drills for £59
anyway.........it arrived today at 10am and by 11 am every single bit was blunt some even snapped in half
so.....we went to local tile shop and bought 27 drill bits for porcelain at a cost of £487 another hour later most of them are useless too

this bathroom should of been finished 4 days ago and is gonna taake another 2 days just to put up the bog roll holder and towel rail

i suppose what im saying is ive learned a lesson here and i wont be touching porcelain ever again

i used to wonder why my mate deliberatly charged £80 a square meter for porcelain to put them off. he has been a tiler 29 years and says he has done 1 porcelain in the last 10 years !!!!!!!!!!!!!!

what a day:banghead::banghead::banghead:

We use a joran drill bit just like a standard bit but have not found anything they wont drill yet. Company on a job spending 30mins a hole on a diamond drill bit we did it in kess than 5, just a cup of water beside you to cool tip. You may not drill that many hole per bit maybe 5-6 but it should be quick enough. I have drilled porcelain sinks with these before no probs. We get them from can fixings i norwich for about £7 ish plus vat each hope this helps.

i once seen a electrician drilling them with a normal 5.5sds bit swith the sds on hammer, gently squeezing the trigger, was amazed to see it flying trhough!

Yeah that's fine until its 5pm on a Friday evening and the tile cracks then you have to take off that tile and chip another one in the process etc, most of the bathrooms I do now have porcelain tiles now I hate it, but have found topps tiles drill bits to be the longest lasting ones , dewalt one easily the worst and I've tried many different makes

By the way its the only bit i have ever used on flitton bricks that make them look like breeze blocks! You must not drill them on hammer not taht you should need too.

porcelain tiles come in different hardnesses, some porcelain tiles drill easier than others.
if it's holes for wash hand basins or wc fixings, radiator brackets etc, it's better to use a 4" angle grinder with a good quality diamond blade and cut them. it'll save you a bit on drill bits. still need the bits though for towel rails, toilet roll holders etc

You doing something incredibly wrong, 1 cheap silverline tile bit from toolstation would do me for a whole bathroom never mind the 365 drills which would last me a good while

You're having a laugh mate. Cheap silveline may be ok for ceramic tiles but won't even scratch grade 5 porcelain

i use an sds bit and melt the tile through

seriously tho i use standard tile/glass bits for most tiles, if the tiles are that hard the customer will have to pay for somebody to come in and drill. The bigests cost to you is labour, wasting time is for thoses that watch Jemery Kyle everyday lol.

You want to bet? I use diamond tile bits usually, but only had this cheap silverline bit, and it worked next time ill record me doing it and post it on here.


Edit: wasnt from toolstation or was silverline this is the exact bit.

i use a simular bit normally.

That drill bit got me through about 7 holes in a bathroom which I tiled with them tiles, Dont know what grade it was though didnt even know they had grades lol but that worked for me so the op must be doing something wrong especially if hes using 365 drills
