I had to drill 17 holes in a very hard 1/4 porcelain floor tile, used on both floor and walls of a bathroom (toilet flange (5), shower panel (4), and heavy shower door (8)). Started with ordinary carbide tipped drills that would cut at best 1 or 2 holes, take a long time, and ran the risk of cracking the tile in hammer mode, using heavy pressure. As I was preparing to drill my last 4 holes, I had to either go buy yet more carbide drills, which were between $3.50 and $6 each, or try the diamond drill I had purchased, but was hesitant to use given the mixed reviews. So, I gave the hole saw a try and wish I had started there earlier. Yes, it was messy, with water running down the walls, but it cut 4 holes faster than the carbide, perfectly round holes, with no chance of cracking the tile. It looks like it could go longer (it comes with 8 seals). So, overall, I say go for it.Note: use it with the collar trapped against the wall and the drip holes closest to the wall. It can be used the other way which might account for some people’s poor performance.

I noticed that most reviews were either “5”‘s or “1”‘s, leading to an average rating of “3”. I’m with the “5”‘s – this product worked perfectly for very thick Italian floor tile. 6 holes easily drilled and there is still life in the bit. Good product.

Used it to drill holes in tile for a shower door. Water dropped out of top container before I could even start. Was able to dip the blade into the bottom container holding water to cool it and keep it clean.

If you need to drill a hole in porcelain tile then this is the right bit. Just follow the instructions.Tip: use some tape to cover all but one of the holes so the water drips slower.Tip: if the drilling slows down then remove the bit and push out the tile core that has collected in the bitUse medium pressure and let the bit do the work.

I was even told by professionals they might break a tile when they install a grab bar in our shower and refused to give a solid quote. Using this guide, the diamond drill supplied and water to keep it all cool there is very little chance of breaking a tile when drilling through it. I had done this before but now, at 86, I was reluctant to do that much work again. While it was quite tiring for my old body I had no trouble drilling the holes and mounting the grab bar in our shower. Just be sure you place the guide exactly over the marked holes and keep the process cooled.
