When I put up my fathers grab bars I ended up ripping out the plastic tub surround and attaching backing to the support members to get the bars in the right places. A diamond bit would be a good start. Be very careful near the edges. Go slowly and you will be rewarded. A bit of water sprayed on the bit helps as well. |

Try something like this: http://tinyurl.com/azxnz Use a spray bottle of water to spritz the hole as you drill. I also use a cup of water to periodically quench the bit. Make sure you hit the studs if it's a grab bar. R |

I think only the one size was needed. As others have said, grab bars must be attached to the studs behind the tile. You can use a stud-sensor tool (electronic gizmo) to find them. -- H |

You might want to do this on the opposite side if you can get to it. Locate studs then measure from a predetermined spot and transfer this measurement to the side you're working on. Hoping you have better luck with your stud sensor. Rich -- "you can lead them to LINUX but you can't make them THINK" |

What is procedure...small hole first then move to 1/8 bit? Look he http://www.diydata.com/tool/drillbits/drillbits.htm Your bit is about three fourths of the way down the page; a carbide tipped spear point. You can find these at any good hardware store, maybe even Wal-Mart, etc. Cost is $5-8 apiece, depending on size and quality. You drill the final sized hole; no stepping up. Drill for screw clearance plus a little for wobble. It is difficult to drill precisely located holes with these bits. Buy at least two. They wear fast in some ceramics. Heat from friction is the biggest cause of failure. Keep the bit cool by dipping it in a cup of water every few seconds. When it gets dull, throw it away and use a fresh one. You are probably not equipped to resharpen carbide tools. Grab bars require drilling through the tile, its backing, and firmly mounting into studs or solid wood blocking in the wall. I think code in most places acknowledges this. -Frank -- Here's some of my work: http://www.franksknives.com/ |

To start with you may want to use a center punch or other sharp harden tipped tool to break the glaze of the tile. Don't hit too hard or you will crack the tile. |

Many thanks. Looks like Hitachi specializes in a bit set made for
porceline tiles. Other brands only indicate ceramic tile drills. |

Once the bit gets started into the hard surface, it goes nicely. Even if the bit is "used" by the hard service, it is cheap to replace if needed. My carbide bits seem to last forever, and they are the cheap ones, too. --Phil -- Phil Munro Dept of Electrical & Computer Engin Youngstown State University Youngstown, Ohio 44555 |
