Hole Saw Set,15Pcs Diamond Drill Bits, Integrated Tile Hole Saw Kit, Coated Core Drill Bits with Hole Saw Guide Jig Fixture,Adjustable Centering Locator Suction Holder for Glass, Ceramics,Tile 6-50mm

Worked perfectly this morning. Don't know how long that they will hold up. But for now I am satisfied.

I am female and know very little about a drill. However I wanted to make some fountains out of old ceramic pots and coffee mugs I had in my house. So I need to drill holes in them. I watched a few videos on how do it it and purchased this set and it worked beautifully. I had no problem at all getting the holes I wanted. Some mediums were harder than other to start but I don't believe it was the fault of the hole bits, I think it was the different types of materials I was drilling holes in. I think they did a fabulous job. I was very very pleased with the results they gave me.

I'll be trying these next week and I'll revise my review if they're not up to par.Looks like a nice set though.Hopefully if I take it slow as per the directions, they'll be great.UPDATE: I had the opportunity to use these a couple of times now.The first was a freak situation where I had to enlarge the faucet holes in a china pedestal sink deck.I took my time and started with a saw that just fit into the top of the hole while squeezing water from a sponge into the top of the hole as I went.It only took a few seconds to get through and made a clean hole.Unfortunately, it was still a little too small, so I stepped up one size and repeated the process.Again it worked perfectly, and this time the faucet fit .I used them again a few days ago to cut holes in some ceramic wall tiles for tub and shower pipes.This time I had a chance to try the guide.As others have said, it's important to make sure the suction cup and tile surface are clean so the suction cup sticks.But it worked beautifully and gave me perfect, clean and professional looking round holes.I still haven't tried them on porcelain tile which is harder than ceramic and more difficult to drill and cut. But since they went through the ceramics like butter, I think they'll be fine as long as I don't try to rush it.

I bought this tool to do a patch job on a couple of tiles I broke as I didn’t want to replace all the tile in the bathroom. I to cut holes into the existing tile to place bubble tile inside it. I call it custom lol but it’s a patch. The grip on the jig is strong and makes drilling through the ceramic tile easy. I kept the area wet and slowly drilled through the tile. I didn’t have any issues using this tool.

Bits cut adequately; however, the jig would not attach to my tile. I assumed this was due to the type of tole I had, but I later tried it on polished granite and it would not attached to that either. I made do by having someone hold the jig in place while another operated the drill. This could not be used without 2 people.

I drilled ~1" plumbing holes in ceramic glazed tile in a shower, and several 3/8" holes in same for anchors. I killed one bit instantly when it heated up. This is to be expected, but I got better service out of some other cheap bits off this site before. Have a reliable water drip system set up before starting.

Missed styrofoam drill holder block not included in my reorder?

I had over 17 holes, various sizes, to drill in 1/2 porcelain. These worked great! Only broke 1 small one in half (my fault, too fast and pushing too hard). They have held up well!I found the "jig" useless. Instead, I would go full speed (JUST to start the hole!!!!) at maybe a 70-50' angle to start the hole. Then SLOWLY change the angle to 90'. I would stop every 5-20 seconds to cool the bit in bucket of water. I would also sponge the hole to get that wet. I would go slow and not apply too much pressure at all. This worked great!Bits held up and work was done. Great bits for the $. Would buy again!
