SHDIATOOL Diamond Core Drill Bits 2-Inch for Porcelain Ceramic Tile Marble Brick Vacuum Brazed Hole Saw 51mm

I havent used this but it looks like others have. I wouldn't think I'd get a rusted bit and all diamond plating was gone on bit tip. Somewhat upset. Looks used and worn out. Guess I'm sending this back. Bought a Milwaukee bit from Home depot cheaper and it cuts through granite like butter.

These are excellent bits. I don't write a lot of reviews but these have been such a help to me. I'm a general contractor and often do my own tile and stone work. These bits cut cleanly right through tile and stone and without wandering. Great quality for the price. They work excellent for shaping as well if you have an odd cutout. They've saved me so much time. Ordering more sizes.

I bought this to repoint my masonry fireplace. Was worried on how to remove the cement head joints since there aren't as many solutions in the US as in England. I came across this solution that threaded on to my standard angle grinder. Glad I did. It tackled both sides of the firebox and most of hearth with one piece. Just make sure to take it slow and if you have any soft bricks, to really hold on to the grinder as it will want to follow the path of least resistance. Only downside is that I wish it could go deeper in one pass. Meaning, I wish the diamond tip part was longer so I could rake out more in one pass. But you just take two passes. And make sure to have the wife hold the shop vac near the brick and your dust problem will be gone.

I used it to cut a 4-inch hole in stucco. It did so in a short time. I suggest buying a mandrel with a pilot shaft sticking out the front to help in getting the cutter started. I didn't have one, so I placed a piece of wood nearby to support the back edge of the cutter.THIS TOOL PAID FOR ITSELF ON THE FIRST USE. The diamond grit held up well. I couldn't see any wear.

Cut holes in a .24” think porcelain tiles. Easy to start and cut the holes. Came out clean and made a nice hole. Don’t see any wear on the bit yet. Very beefy bit. I had bought another name brand locally for 3x the cost as this, just in case this didn’t work, but will return. This is from China. Came mailed from China pretty quickly. Would buy a set if I ever needed to do this again. The diamonds are at least 1/2” up the bit so I imagine I can use it to polish or enlarge the hole. I used it to rough cut holes in porcelain tile I was installing in a new shower.

I had to drill a 3" hole through a hallow concrete block wall to install a mini split A/C. I purchased this to connect to my grinder. I was not looking forward to drilling the hole thinking it would take 20-30 minutes just to go through one side of the block. It took less than 20 seconds to cut the hole! I would definitely recommend this to drill holes through concrete block - worked perfect!

absolutely did a great job on my brick wall. I bought an arbor as well since i wasn’t sure it would be long enough to make it all the way through.But this really went through the brick quickly. one tip. I added water as started penetrating the brick and it noticeably slowed it down. It turned the brick dust into a paste, so for brick I wouldn’t add water.also i was also impressed to find a note from the manufacturer (yes from China) backing the product. nice touch.

I knew when I purchased this it was not going to be the quality of a $200 bit. It lasted just long enough to core through my 10" wall, so job done. I did expect it might core at least a couple of holes, but it didn't.

It worked well for the job I needed. But didn’t realize it didn’t come with the 5/8 pilot.. and of course in Ontario all three places didn’t have one. So I went and made myself one that worked. Keep that in mind if you’re buying this right before finishing a job.

Drilled a dozen or so holes with little wear on bit. These are far superior to the several other diamond bits I've tried. I'll definitely be getting more of these!

I made 9 holes through 9mm ceramic. It was relatively quick around 1 minute per hole with some breaks to cool off the bit in water every 15 seconds. The diamond bit is still in decent condition and could be used for some more holes.

I just used it last week to drill a hole on the granite countertop. It worked well. I finished the hole around 10 minutes with the dry drill. During the period, I took it out every one minute to make it cool. The hole exactly fit with my water filter system faucet. I turned on a vacuum to clean the dust during the drill. I highly recommended it for handy work at home.

This product was fantastic , super heavy duty! Drilled many holes for a recent reno. Gets through granite quickly and easily and leaves quite a smooth hole. Highly recommended and worth every penny!
