Cut some ceramic tile with them. Worked as I expected. Good quality. Cut fast. Easy to use. I made a template to hold bit so it was easy to use.

Does what it says cut 2 holes through 1 1/4” thick firebrick. Cut was clean but did have to applied some pressure to get through. Cutting speed was about a minute to get through the material. Lots of diamond grit still on hole-saw after the 2 hole. I believe it will last a bit longer. Function like the description said and it was a fair price.

Fits on a grinder not a drill, lube inside it to ease with cutting. Works really well I used it to cut hard ceramic tile

I used these to drill through very hard quartz, the full depth of the bit. They held up great. I kept the bit submerged throughout the drilling.

I am happy with the product normally and it did its job. However, when you use it with water, dust from the drilled hole become solid and stuck inside of the item. Taking out that piece took longer than drilling. Side hole was not enough to take that solid dust part from inside. Unfortunately, I had to go to nearby store and purchase more expensive Milwaukee brand. It seems more weak but did better job.

This worked quickly for my brickwork. I am installing a high efficiency furnace that requires 2" nominal PVC pipe. Outside pipe measurement is 2 3/8" diameter. The 2.5" hole saw worked perfectly and made clean cuts through the brick. I had to stop half way and hit the brick with a chisel to crack off the end allowing the bit to get deeper into the brick. However, it had no issues picking up where it left off and grinding out the brick. I used a 4amp angle grinder -- this bit attaches directly to a standard angle grinder bit. 4amps worked good for my purposes -- 2 holes. However, with pressure the 4amp slowed down at times. I think a higher amperage angle grinder would drill through a solid brick in 2-5 minutes easily. Great for jobs around the house.

Summary: Adding a few grab bars to dad's shower. I used a lot of products for this project, so including all related products in this review.Recommendation:1) When mounting grab bars, it's always easier if you can find the stud to attach to. In this vertical install, I decided to use a stud and Wing-Its anchors; partially because I wasn't sure I could hit both, and didn't want to put two fasteners vertically (on either the right or left only), but that would also position the bar in the shower a little too far in (towards the shower control).2) The WingIts requires a 3/4" hole through the mounting material. For tile, this can be especially challenging. I used the SHDIATOOL diamond 3/4" bit, with the DRILLAX adapter to get through the tile, and then used the 3/4" BOSCH bit to finish through the dry wall. Also used the BOSCH bits for the other small hole. Having the right tool for the job is the difference between project completion, and a messy, disaster.Related Products:Moen R8924P Home Care 24-Inch Concealed Screw Bath Safety Bathroom Grab Bar, Peened ~ $30Pros: Moen name, includes stainless screws.Cons: None.Conclusion: 5-starshttps://www.amazon.com/gp/product/B001EI0TJ4Structural Grab Bar WingIts, PK2 ~ $14Pros: Heavy duty, highly rated.Cons: Cost ($7/anchor).Conclusion: 4-stars (cost)https://www.amazon.com/gp/product/B004CCRJWOSHDIATOOL Diamond Core Drill Bits 3/4 Inch ~ $13Pros: Right tool for the job, looked brand new after drilling two holes (with proper technique, including cool water).Cons: None.Conclusion: 5-starshttps://www.amazon.com/gp/product/B07213KCN9Drilax Core Drill Bit Arbor Adapter ~ $15Pros: Allows SHDIATOOL bit to be used with drill (instead of angle grinder).Cons: Cost (a little expensive).Conclusion: 4-stars (cost)https://www.amazon.com/gp/product/B0737H7CMXBOSCH GT3000 Carbide Hammer Drill Bit Set ~ $25Pros: Cuts great; carrying case.Cons: None.Conclusion: 5-starshttps://www.amazon.com/gp/product/B001GNC8RS

It would not thread completely into a standard hole saw mandrel (2nd pic) Made it about half way and it locked down like the thread pitch was off. Put it in a vice and locked it down w a wrench. Sacrificed a mandrel for it, no biggie. Start real slow and angled till u get a groove then straighten up. Worked good and was 1/3 the price of one at Lowe’s and HD. The granite core stayed stock in bit so I either have to figure out how to beat it out or it’s a one and done bit. If I have more than one hole to do keep that in mind. Would buy it again.
