hackjam Posted September 18, 2016 Share Posted September 18, 2016 Whats the procedure for drilling holes in floor tiles? I seem to be going through a drill bit for every hole, These floor tiles are very hard. Link to comment Share on other sites More sharing options...
Crossy Posted September 18, 2016 Share Posted September 18, 2016 Yup, I have the same problem, ceramic floor tiles use up bits like nobodies business. Keep the speed down and use coolant (water). I just re-sharpen the bit after each hole. If you can find diamond bits they will last longer, but don't be tempted to use hammer. Link to comment Share on other sites More sharing options...
Lamkyong Posted September 18, 2016 Share Posted September 18, 2016 are you using a masonry (high quality ) drill bit Link to comment Share on other sites More sharing options...
bankruatsteve Posted September 18, 2016 Share Posted September 18, 2016 I'm curious to know why you want to drill holes in the floor, but whatever... There are special drill bits for ceramic tile. They look kind of like an arrow head. Otherwise, I first use a center punch to make a small chip in the tile, then using my smallest cement drill (with no hammer to avoid chipping) to make initial hole, then using the size I need cement drill to finish.

Crossy Posted September 18, 2016 Share Posted September 18, 2016 No, I sharpen regular masonry (tungsten carbide) bits, bit difficult to sharpen those little diamonds Bad formatting on my part. Fixed to save future confusion. Link to comment Share on other sites More sharing options...

It worked perfectly. I left the house after a few years and then went back again after another three. Someone had ground off the door stop and left a small circle of epoxy. Edit: Just checked: the base of the doorstop is still there So epoxy is OK if you're really really sure you want it there.

lopburi3 Posted September 19, 2016 Share Posted September 19, 2016 You can buy these diamond drill bits designed for tile to make hole through the tile itself - they work great in regular drill mode and do not slide. Once into the backing cement or brick use regular masonry drill bit to drill out to require depth and you can use hammer mode. Link to comment Share on other sites More sharing options...
hackjam Posted September 19, 2016 Author Share Posted September 19, 2016 Any idea where in Pattaya I can buy the diamond drill bits? Link to comment Share on other sites More sharing options...
lopburi3 Posted September 19, 2016 Share Posted September 19, 2016 I buy at HomePro here in Bangkok - suspect any large building supply store will have as quite common these days - in the past could be hard to find as most local workers do not want to change bits and they do not last long if used in cement much - and a lot more expensive than the normal cheap masonry bits used. But for me they pay off by getting the start exactly where you want and without any chipping (even if done at tile joint). Having wife am subject to strict oversight controls.

It's what I do also. The arrow head shaped bits drill through ceramic tile pretty easily without damage/chipping of the tile where masonry bits will have a hard time and frequently chip or even crack the tile. Once through the tile you should switch to the regular masonry bit. Although the arrow shaped bit will drill through the concrete with ease, drilling into concrete will also shorten the bit's life span...and these arrow head shaped bits are a little pricey in comparison to the regular masonry bits.

Kwasaki Posted September 19, 2016 Share Posted September 19, 2016 Yeah good but diamond ones are a phaeng in the wallet. I put a small piece of sellotape over marked drilling place then use a very small size masonry bit first there cheaper then go to the bigger size the bigger ones l find last longer that way.

lopburi3 Posted September 19, 2016 Share Posted September 19, 2016 You can also buy without diamonds - carbide is very cheap as below from Ebay for about 65 baht for set: http://www.ebay.com/itm/4pcs-Marble-4-6-8-10mm-Glass-Spear-Head-Cretive-Drill-Bits-Ceramic-Tile-Set-/331948088996?hash=item4d49a5dea4:g:h7UAAOSw65FXu8YL Link to comment Share on other sites More sharing options...

Mrjlh Posted September 24, 2016 Share Posted September 24, 2016 I simply place masking tape over the the spot I intend on drilling. Silver duct tape works too. The tape allows for extra traction until the drill bites past the glazing slick outer covering. Start slow and use water to cool the drill bit (masonry). I use a simple water sprayer. Apply steady pressure and slowly increase the drill speed. Be patient. Never have any issues. Never use a center punch you'll likely to crack the tile. Start with a small diameter then the one size you need. I've found if the insert says 8mm hole I always go down one to two mm. The drills then to wobble and the hole gets larger than planned.
