Drilling tiles - idiot prevent question
Just checked the FAQ but would like to double check:
I need to drill an 8mm or so hole in a glazed ceramic floor tile (bog screws). Masonry drill on slow and some insulation tape to stop wander? Am I correct... Might be near the tile edge... Can't afford the f*ck up fairy visting here! Ta Tim |

For glass AIUI you'd make a little 'well' around the hole with plasticene and fill the well with oil to lubricate. That's a good idea. I'll nick the kids' PlayDoh (again). If it all goes horribly wrong you'll just have to persuade the Decor Inspector that pedestal mats are in vogue again. If that happens, the Decor Inspector will decide I look good wearing testicle ear-rings! Cheers! Tim |

Ta Tim Try one of those for starting - http://www.screwfix.com/prods/53634/...20TILE-_-53634 They are fantastic. One hole established, build up the dimensions slowly. |

B-) I'd get an 8mm tile drill either one of the flat pointy things or a "pirana" from B&D IIRC. To stop the wander gently center punch the glaze at the right place. Nice a slow to start untill you get a feel for how well the drill is cutting. I'd not bother with a plastercine well and definately not oil of anysort as a coolant/lubricant (it'll get into the grout...) little bit of water from a sprayer or small squirty bottle will do. -- Cheers Dave. |

Bosch multi purpose drill bit http://www.screwfix.com/prods/82523/...-Bit-8-x-250mm Very sharp point compared to normal masonry bit. Start without hammer action, push firmly until you hear a sort of crunching sound (point of bit penetrating tile glaze) then start drill on slow speed. These bits are bloody wonderful things, buy yourself a set. -- Dave - The Medway Handyman www.medwayhandyman.co.uk |

I use a plant mister to occasionally spray the hole and drill bit. If the bit gets too hot it will blunt. Very slow process though.

Am I correct... Might be near the tile edge... Can't afford the f*ck up fairy visting here! For starting in such materials I use some tape, then put the bit in a wheel brace, hold the wheel (not tbe handle) and rock it so that the bit does about a quarter-turn back and forth. It can't wander off as it never turns enough. Also, with no noise from a motor, I can apply pressure until a slight grinding noise is just visible, so I know that the bit is beginning to bite but isn't going in too fast. Out of curiosity I once put a 6mm tile bit through a wall tile by finger power alone - not recommended but does show how good the correct bits are. -- Peter.

Which could be used on the floor. Had lots of holes to drill being a bathroom and tried masonry, tile and those Bosch universal types, and destroyed them all. Screwfix sell diamond core drills which do work, although slow. DeWalt last longer than the no brand ones. Once you've made a hole they can be enlarged with a Bosch one. -- *I wished the buck stopped here, as I could use a few* Dave Plowman London SW To e-mail, change noise into sound. |

Two drill bits, ideally two drills (esp. if you're Mark out with masking tape, well rubbed down, and personally I like to try a manual centrepunch first by pressing (not hitting) a carbide scriber point through. There's little risk of cracking a tile, but there's still some and this increases if the tiles are poorly supported beneath. Much depends on your individual tiles - some have really hard glazes that increase the risk of skidding. Start out with a "leaf" bit, usually sold for glass (Axminster) Start out gently and don't worry about cracking, worry about sideways skidding instead. DO NOT HAMMER. For that reason I prefer to use two drills for this, plain drill for the leaf and SDS for the masonry bit. This also saves me swapping chucks, but mostly it's to avoid finger trouble when switching one drill in and out of hammer mode. Use the leaf to go through the surface porcelain glaze, out to the full diameter of the hole. Usually you can get right through the back full diameter too. This hole should be oversize on the final fitting, so that there's no contact between the bolt or screw and the tile. Then switch drills to your SDS and a simple SDS hammer bit for drilling the wall itself. Drill centrally, without thumping the tile. |

That bit about the hole being oversize is really important, especially if you then use a plug in the hole. If you do the plug should be inserted *past* the tile or it will exert sideways force as it expands. Then switch drills to your SDS and a simple SDS hammer bit for drilling the wall itself. Drill centrally, without thumping the tile. Personally I've never had any problem drilling tiles. No hammer, no push, very slow drill, relax. |
