This drill system worked great for making 6 holes in some porcelain floor tiles. Took perhaps 20 minutes for all the holes. But then I followed the directions, made some minor adjustments to make the system work on the floor AND,. being a dentist, I’m familiar with working with porcelain in the clinic on a daily basis.Working with most porcelain is simple — fresh diamond, high speed (fast as you can get), lots of water, not a lot of heavy pressure (don’t slow the drill down with pressure), and nibble at it a couple seconds at a time then release to cool and clean, repeat till done.I also made sure that the drill bit didn’t have to go past the tile. Diamonds don’t drill thru stuff like the wood that might be underneath the tile all that well. Also, porcelains can vary significantly in hardness with zirconia (used in the space shuttle) being super hard — however, most tile porcelains are managable with normal diamond cutting systems..FYI, dental diamond drills that are used for cutting dental porcelain run up to 300,000 rpm and are bathed in constant water/air spray to stay cool. At these speeds, less than a second without coolant spray and the porcelain turns white hot and you burn out your diamond. Drilling holes in porcelain tiles isn’t that much different. It’s just a bigger hole, plus a bigger drill and a lot slower drill speed, and lots of water.For the horizontal floor application, I placed duct tape over the open end of the reservoir box to allow water to fill the box for cooling the bur. I used a basting bulb from the kitchen to fill the reservoir with water before inserting the drill bit. The drill used was an older Ryobi 18v at #2 high speed in two second increments with just enough pressure to barely slow the drill down, lifting the bur up enough to see the dust created flow into the water of the reservoir. I had to refill the water on some of the holes to keep the water above the hole in the drill bit. I had to change the adhesive pads with each hole.I’d highly recommend this drill bit to anyone who can follow directions… If you’re going to make it up as you go, good luck with that…

Went through the tile and thin set cleanly.

Holds water well. Still takes time to cut through tile . Nature of job .

I was apprehensive about drilling ceramic tile but this made it simple. I wanted to mount a soap / shampoo basket in a newly tiled shower. I needed to drill four holes – and I was worried about the bit wandering while drilling. This worked very well. It wasn’t difficult to get the hang of and was easy after the first hole.A small piece of sponge in the water reservoir helped control the drip rate.

Great.

Drill bit works great but the water cooling system drained before I could start drilling. Ended up doing away with the cooling system and frequently dipped the bit in water to clean and cool it.

Did a great job on the ceramic tile!

This bit works better than most masonary drill bits BUT it is only good for about 4 to 6 holes. So you need to add another $20 to your cost for every towel holder or toilet paper holder since each devoce requires another bit to drill.

Worked as well as could expected. Was a bit messy but then again so is a spray bottle.

When i needed a drill for porcelain shower tile to install grab bars, shower fixture, & shower door frame I found this drill at Home Depot. Read the reviews about drill life bieng short so I bought 2 kits. I was able to drill all 26 holes required with one drill however. I did need the 2nd kit because there weren’t enough double stick tapes for the water container (they become less sticky and in a few holes won’t stick any longer). Anyway, I had good luck, just followed directions on packaging. I would buy these again.

The stickers to hold the reservoir in place were unreliable. The bit did a nice job of cutting the hard tile.

The water delivery system made easy work of 6 holes thru ceramic tile. Use a small nail to clear the bit after each use. Use a few shots of canned air to dry off the self-adhesive seal before next hole. Follow directions about drill-and-lift and this will last for many repeats.

This tool did the job for me when nothing else could, excellent product.

Works well. Limited by the number of sticky tabs though. Usually about 8.

I like the concept, and it worked ok. Like any drilling into porcelain tile, it takes patience.

Sharp bit, cut really well and price was competitive to other brands.
Mylene Halvorson (verified owner) –
Too expensive and too much trouble to use. Worked ok but a different drill for tile worked much better.

WE DRILLED MULTIPLE HOLES IN THE TILE AND IT STARTED EASY AND DID NOT BREAK THE TILES. IT WORKED EASIER WITH JUST A SQUIRT BOTTLE OF WATER TO LUBRICATE THE BIT.

Great for use on walls!
