Used on porcelain tile, but did use a pointed tile bit to start. Can't get at Lowe's without special ordering. Much cheaper and no difference in proformance. Don't drill tile without these.

Let me start off by saying, the price for the quality is impressive. My husband use to buy similar bits from the big box stores at 20 dollars apiece before taxes. With this set you get 6 for 33.99 dollars plus there is a 2 dollar coupon available as i write the review bringing the price down to 31.99 and the quality is just as good. You would use these on marble, granite, glass, ceramic tile. Weird that they don't state they are ok for porcelain tile within the description. But they are, and they cut just great. They have a wax plug in the center too keep them cool while drilling. The wax won't last long, and I am not sure I would trust that to keep them cool anyway. I would recommend constantly dipping them into cool water as you drill, as to not burn out the diamond coating. There is quite a bit of diamond on these, triple the ones you see on Amazon with a chrome colour shank and selling for about a dollar a piece. So, these should drill at least 15 to 20 holes IF KEPT COOL. The other ones typically drill 3 to 4 holes in porcelain tile before they are toast. Remember to always start the bit on an angle so as to get it scored, slowly straighten the bit as you are drilling to get a complete round indentation in the tile before you try and drill it like a regular drill bit into wood. If not, they will walk right off the tile, scoring it as it goes, and essentially ruining the tile. The only drawback to these compared to others my husband has used is, they do not have a cut out on the side of the bit, to clear out the plug, after drilling a hole. My husband solved that problem by drilling out the wax and pushing a drill bit into the rear of the shaft to clear the plug. If you dont you will get the plugs stuck in the shaft rendering the bit pretty much useless. Other than that, they are perfect. They also come in a plastic container to keep them from getting lost. My husband has drilled well over a thousand holes into tile using these diamond style core bits and has stated these are as good as he as ever tried. He has used them on porcelain, marble, ceramic and granite, and they cut well into each, just remember to keep them cool. Also if you are drilling into something thick you must drill out the wax or it will bottom out and not drill any further than about 1/2 an inch. I hope this helps in your decision making.

These drill bits have a good amount of diamond covering on the tips and are plugged with wax so they are supposed to be used dry and the wax cools it down. I use mine to add holes to glass and I still use water to cool just incase. They cut well and smooth. I have used them multiple times and they still look good as new.

As a graduate degreed engineer I appreciate good tools and as the owner of a handyman service with a focus on tile installations I've used many types and brands of diamond hole saws and drill bits to make holes in various types of tile (ceramic, porcelain, marble, granite, etc ...). Some of the Amazon cheapies have lasted as long as the spendy Milwaukee ones from my local big box store ... and some haven't. In general they all seem to function about the same to start with, but some are more durable over time.I've bought these diamond Mgtgbao branded bits before and they've been very durable, especially given the reasonable price tag. Not as durable as the expensive Milwaukee bits I use when I have to buy locally, but plenty durable for the price. I've only used these while using water to cool the bit, so I have no idea if the wax filling does much, if anything, when used dry. Definitely a worthy bargain in diamond drill bits, I'll be buying more when these wear out.For now these seem to be about as good as anything else and are bargain priced, so I'm pleased. Very pleased in fact.

I had a project in an older home that involved drilling through one-half inch thick porcelain tile over one inch thick cement backer board. Very thick! These bits worked well to drill clean holes, but keep in mind the following to maximize your success:1. Start the hole with the bit at as close to a 45 degree angle to the surface as possible, and while drilling, very slowly ease the bit to the 90 degree position.2. While drilling, every 5-10 seconds, spritz the hole with a water spray bottle to keep the end of the bit wet. This maximizes bit life as well as keeps the dust level down to near zero. Put an old towel on the surface below the hole to catch the water and dripping sludge.3. Patience. Don't force the bit hard into the hole, just use light pressure and let the diamond grit slowly eat its way through.4. Expect your bits to last roughly six to twelve holes, depending on the hardness of your particular surface. Again, keeping the bit and surface wet will extend bit life and cut your bit costs.5. Best "secret" tip: This one is not obvious, but important: Keep an eye on the very end of the bit (the drilling end) because wall plaster, cement, etc. can easily build up in the hollow void at the end of the bit, and it gets compacted in there and forms a hard little plug. This plug severely hinders the circular drilling edge of the bit from penetrating a surface. Trust me on this one, it makes a huge difference in drilling ability and speed, and if you notice the bit barely making progress through the surface, it might not be worn out - it might just be clogged. So look into the end of the bit, and if you notice a plug has formed inside the hollow end of the bit causing the end to appear almost flat instead of the desired concave, use a very small flat head screwdriver or pick of some sort to dig that plug out. It may take some force but keep digging and scratching away at the edges of it and eventually the plug should pop out like a little stone. Then you'll notice that the end of the bit appears much more concave, and the bit will drill twice as fast again.

This was the first time I've ever had a need to drill into brick and when I saw these diamond bits I thought I'd give them a try. I used the 3/16 (smallest) bit to drill two hole's for screw anchor's in my house's bricks by my front door. There were existing divots where I ruined what I thought was a masonry bit on my first attempt a few weeks back so I can't speak to how easy/difficult it may be to start a hole with these bits. I started in drill mode slow speed on my drill and it seemed to go ok. I did a little in one hole and then in the other, looking to go approximately 3/4 inch deep. I started having to use a little more force after it got about 1/4 inch into the brick and at that point I started to smell what I suppose was the wax beginning to melt to cool the bit but it didn't seem to be getting much deeper. I was pulling the bit out every 3-5 seconds to blow the dust out of the holes and then decided to try the higher speed. I swapped between higher and lower speeds a couple times and started using more pushing force as it didn't seem to be making as much progress. I finally got the the depth I needed, brushed the bit off and took some pictures of the bit. I couldn't get my phone to focus very well on the bit, but I think you can see fairly good that the bit looks to have a pretty good abrasive surface on it still. I think if I had to drill into brick again I would probably use some water while drilling as the ad suggested for additional cooling, but having no prior experience drilling into brick I can only say that it took longer and more force than I expected. I gave the bits a 3 star rating since it worked and got the hole's drilled.
