Musste ein Loch in eine Granitplatte bohren war etwas skeptisch nachdem ich die Rezessionen gelesen hatte nachdem einer schrieb es geht wie Butter aber ich wurde eines besseren belehrt ,es funktioniert wirklich Super und der Bohrer hatte fast keine Abnützungserscheinung Also Topp weiterempfehlen.

This drilled a perfect hole in a concrete block. I bought 2. A 90mm and a 68mm. The 68 was real close to the void in a concrete block. The 90mm was bigger, hit the interior walls and I had to chisel it out but it still worked great.

This drill bit made a clean cut through my quartz countertop. This saved me a lot of time and money to get someone just to drill a new hole for my RO system

These are exactly how they look. I needed to cut a hole in a granite countertop and these worked. After 3/4 of the hole was cut, It didn’t seem like it was cutting as well as when i started so swapped out to the other one. The second one cutter better. I looked closely at the diamond cutting edge and it looked okay. I didn’t see any diamond missing. Maybe it was getting a little dull. For the price they worked great. If I were a contractor, I would go with a higher quality bit. I did use water and didn’t have much problem getting the hole started. The hole did drill a little oversized. I would buy again if needed to drill a few holes.

We needed to drill a hole for an instant hot water faucet and this blade cut through the counter very fast and didn't require much effort. The bit left a perfect finish and is a great value for the price.

I bought a Home Depot hole saw similar diameter to drill into clay pots as planters, could not drill though ceramic…took for ever and heavy pressure, still not get through. Got this hole saw, love it! Works great, having 2nd one back up is great! Today i drilled 5x ceramic plates/bowls to use for plants/flowers. Bit tip is still strong, put pressure and angle at different point for better grip. Drilled with a bit of water to control dust, and cleaned bit, looks as new. Love it, highly recommend. Diameter is good for most clay ceramic planter types.. on my favorite, to purchase again when my bits wears.

I decided to install an instant hot water dispenser at my house. As shown in the photographs, I had to cut a perfect hole through 1 1/8 inch granite. After watching a few YouTube videos and once I garnered the courage to proceed, I ordered a two pack of these diamond coated bits. As you know: A MISTAKE DRILLING INTO GRANITE COUNTERTOPS IS VERY COSTLY so be sure to really learn the best practices which include: 1) carefully measure your placement of the hole and get a second opinion on the placement - once you drill, you can’t change your mind, 2) use painters tape to cover the area where you’ll be drilling which creates two advantages: the ability to clearly draw a circle exactly where you want to cut and, importantly, to minimize the ‘walking’ or sliding of the bit when you start drilling, 3) start cutting at an angle to make your first small cut and then slowly ease the drill into the vertical position, 4) be sure to keep the bit cool / wet by dripping water in the cut area as you go or dipping the bit into a bowl of water. TYPE OF DRILL: I used a less commercial / standard drill and it required that I change the battery half way through. Also, I ended up using both bits (changing to the second bit about half way through). The cutting was tough and quite tedious, but I was triumphant and had some serious bragging rights afterwards! I’ve done a few handy things around the house but this was a bit more daunting than the average. If i had easy access to a professional for this type of cutting, in retrospect, I would probably have paid to have this done given the how costly a mistake could have been. While the use of tape and the angle cut to start decreases the risk of the blade / bit ‘walking’, the risk is still there. My suggestion: if you’re confident after watching at least 2 YouTube videos, buy these bits and go for it. One final thought: I’m giving these bits 5 stars because they were literally half the price of the ones at Home Depot, because I cannot compare them to more expensive / name brand versions AND because I was successful (saved a few hundred bucks not having to pay a pro). But, I would be singing a different tune if I caused irreparable damage to a $2000 slab of granite. Good product and good price. Confident user not included. ;) — good luck to you.

I purchased the 1" Diamond hole saw bit, worked great on my granite counter top, i used with a makita high speed drill. Hole only took a couple of minutes, I only stopped once and awhile to apply the vacuum to dust and squirt a little water. No issues. read the directions and use a corded drill.
