drilling wall tiles
having recently tiled the bathroom I'm now looking to drill a few hole in
the tiles. the problem being that the tiles are approx. 9mm think and are limestone/porcelain. It has taken about 30 mins to get one 6mm diameter hole done this morning with a combination of a 6mm diamond tile cutter bit and a 6mm carbide tipped SDS. While the tile bit does slowly grind away at the tile this is a long and laborious process, the bit used is new and a low drill speed was used. keeping the area wet is a little difficult given that its half way up the wall. the current tile bits I've got were the cheap option, two for about the same price as one Bosch tile bit. I wil probably at least try out th eothe roption in my local B&Q but is there any merit in going for the tile bits available at screwfix http://www.screwfix.com/app/sfd/cat/...60073&id=80273 given that one bosch tile drill is £6 in B&Q, these seem an expensive option at £21, does anyone have any positive experience with them that could justify the price, or are there any other suggestions for alterntive drills bits? cheers David |

Given the trouble I've had with the cheapo bits I can see the order going in tomorrow, first off I might check out a few local merchants to see if I can get hold of any quality gear locally... but then again the wife's been waiting 4 weeks to get the sink back in so what's another couple of days. cheers David |

Well are you trying to drill limestone, or porcelain, or ? I guess you do mean porcelain, because of the time it takes! It has taken about 30 mins to get one 6mm diameter hole done this morning with a combination of a 6mm diamond tile cutter bit and a 6mm carbide tipped SDS. While the tile bit does slowly grind away at the tile this is a long and laborious process, the bit used is new and a low drill speed was used. Keeping the area wet is a little difficult given that its half way up the wall. I normally use ordinary cheap masonry bits - just sharpen your TCT bit, put more of an angle on it than appropriate for masonry so it looks like a tile drill (it then *is* one). To keep it wet, use a bit of hose! What drilling machine are you using? Are you using hammer action or not? N.B. bits blunt quickly in very hard stuff and you will need to "touch them up" (ooh-err missus!) often. J.B. |

My porcelain sink just laughed at my new Bosch SDS bit. I ended up using (drill) mounted grinding stones to go through it. Still took about 1/2 hour though (with stops to let bit & sink cool down) to get through :-( Cheers, Paul. |

Just mark the centre, carefully scratch the glaze to score/break it with a tungston-carbide tipped scriber, put masking tape over it to stop the drill wandering, and drill fairly slowly with an ordinary masonary drill (rotary, no hammer.) Piece of cake. If you need a large hole, make drill a small one first, then craze the glaze (sic!) around the hole and enlarge it and so on. -- Woody |

Piece of cake. I've tried using regular masonry bits on vanilla wall tiles. Yes, the masonry drill will do the business. But nowhere near as easily as a proper tiling bit.

On regular wall tiles drilling them is a doddle, but the ones that I've got up are 9-10mm thick porcelain. I'm looking at about 20mins for a 6mm diameter hole using a combination of 6mm and 8mm tile drills and a 6mm tct drill. I persevered with using standard Bosch and B&D tile bits but as I've still got 9 holes to drill to mount the shower rail, screen Get a grinding wheel (pref. with water feed or trough), sharpen some ordinary TCT masonry bits so that they look like tile drills. Drill the hole and change bits regularly! Sharpen bits, next hole... -- J.B. |

Sink was secured to the wall, two screws holding it firm at the lower edge at the back (where they invariably are). I discovered that the sink wasn't actually sitting on the pedestal, but was floating a couple of mm above. Which suggests to me that this sink was being held in place by the sealant - the screws wouldn't hold it there I'm sure. Perhaps I'm just over cautious about these things but I thought the general idea of the pedestal was to take some of the weight of the sink. I wouldn't feel comfortable fitting a sink like this where the sink is pulling on the sealant with virtually all its weight, and the sealant is pulling on the ceramic tiles. The ceramic tiles are pulling on the adhesive, and the adhesive ..... PoP --- If you need to contact me please submit your comments via the web form at http://www.anyoldtripe.co.uk.

Sharpen bits, next hole... I never thought of doing that! Thanks for the suggestion. Lots of problems are caused by blunt tools (ooh-err!), even down to using a carving knife that's been used to cut meat on a china plate or whatever.It is really, really worth sharpening TCT bits every so often (or minute, in your case, perhaps!).
