Daedalus Posted July 27, 2016 Share Posted July 27, 2016 As above. Any recommendations? I've got the general principals just wondering if its worth shelling out for some of the diamond bits or just those arrow shaped tile/glass drills. Thanks in advance Link to comment Share on other sites More sharing options...
PeterW Posted July 27, 2016 Share Posted July 27, 2016 Got a cheap arrow shaped one that has done most things (including glass) and is fine. Take it slow and use a spray bottle with water in to keep it cool Link to comment Share on other sites More sharing options...
Vijay Posted July 27, 2016 Share Posted July 27, 2016 use a tile scriber to make a point in the tile, then the drill won't slip. I've used normal drills plenty of times, start off slow till your through the glazing and no hammer action Link to comment Share on other sites More sharing options...
Declan52 Posted July 27, 2016 Share Posted July 27, 2016 Depends on the tile. A normal drill bit won't even mark a porcelain tile. I had to buy a 6mm diamond tip bit for mine. For ceramic an ordinary masonry bit will be fine. 1 Link to comment Share on other sites More sharing options...
ProDave Posted July 27, 2016 Share Posted July 27, 2016 +1 to the "arrow shaped" drills. these are them http://www.screwfix.com/p/erbauer-tile-glass-drill-bit-set-3pcs/53634 I have been using a set for years, they just work, have not yet found a tile they won't drill through.

Nickfromwales Posted July 27, 2016 Share Posted July 27, 2016 The heat generated when drilling porcelain is the number one reason that they break when being drilled. A water bottle hand spray and a diamond bit is essential, particularly when the hole is within an inch or two from the edge of the tile. Is it ceramic or porcelain, do you know?

They lasted 1 hole on my porcelain tiles. Had to go for a proper bit in the end which went through it in no time. Link to comment Share on other sites More sharing options...

Porcelain and I've got about 2 dozen holes to do throughout the bathroom once the tiles are eventually finished. I'll give the cheaper arrow shaped ones recommended by Dave a quick go and see how far I get. Link to comment Share on other sites More sharing options...
Bitpipe Posted July 28, 2016 Share Posted July 28, 2016 Our plumbers have burned through tens of diamond bits this week while drilling the porcelain tiles - even taking it slow and using water. They've switched to cheaper arrow bits and are making much better progress. Link to comment Share on other sites More sharing options...
Onoff Posted July 28, 2016 Share Posted July 28, 2016 I have been using the cheap arrow headed ones from Toolstation. Bought the set and a 10mm one too. All good. Also got a couple of grit edged hole saws which I use for copper pipe through tiles. Link to comment Share on other sites More sharing options...

My 30mm one is at least a year old and does between 5 and 7 holes per job. That's through porcelain and ceramic. Just use plenty of water and keep the tile cool. A damp sponge works well also.

The brand has worn off it now. But it was one of the thicker walled ones with wax in the Center. (6mm) Link to comment Share on other sites More sharing options...

Tiles are not fancy, own brand from our local shop (£33/sqm) but very decent quality. Link to comment Share on other sites More sharing options...

Ferdinand Posted July 29, 2016 Share Posted July 29, 2016 (edited) Has anybody here used / does anybody use the Two Hammers technique? Obvs no good if the tile is already on the wall. Edited July 29, 2016 by Ferdinand 2 Link to comment Share on other sites More sharing options...
Nickfromwales Posted July 29, 2016 Share Posted July 29, 2016 Id like to see that done with a porcelain tile It would go something like "whack, smash, bin". I can't imagine all that banging wouldn't have compromised the integrity of the tile. I wonder if that's how they did it 'in the old days' ?
