Good quality
Used it to drill two holes in flagstone set in concrete. Drill bit worked good, with one exception. It was difficult to extricate the core that was drilled. Core removal slots should be more numerous and on more than two sides of the drill bit.

As with the other Vevor Diamond Core Bits. Long life is Great Value and Quality. I would highly recommend it to any contractor needing this type of equipment.

The Diamond core products that Vevor sells are excellent. Value & Quality. Drilled 6 holes and no noticeable wear and tear on bit. I would highly recommend it.

Awesome value
This core bit worked perfectly to core a hole for a recent mini-split HVAC install through a CMU wall. It chewed right through the block with ease. I used a standard 1/2' Milwaukee drill and a spray bottle in my application and the bit survived to drill another day. I think you could get a lot of use out it before replacing as long as you keep the bit wet. Bottom line is it is a good value and good quality. The included grinding disk is a plus and also good quality.

Worked good cut 6 holes threw 8 in concrete still seamed to cut the last hole good . I would buy again if needed to very reliable drill bit

Drilled through 8\" cinder block with no problem.
Drilled through 8\" cinder block to shorten dryer exhaust pipe. Dryer works much better and should result in lower energy usage.

This worked really well, BUT!
This worked really well drilling through the side of a concrete storm sewer. BUT! I had to buy a $240 hammer drill. This will not work in standard 3 tooth chuck of the hammer drill I already had.

Mr
I have not yet used this bit, but after reading some of the reviews, I felt a comment was in order. People are complaining about the pilot bit, but if it is used correctly, it is a huge help. Note the use of the term "pilot bit". That means you need a pilot hole. The proper way to use it is to remove the pilot bit from the mandrel and insert it by itself, into a hammer drill and use that to drill your pilot hole. Then you install it back into the mandrel and screw that into the coring bit. The coring bit should be used only with rotary motion, not hammering, unless you're fine with huge breakout on the back of your hole. I will write a follow up review or update this one after I actually use it, but I wanted to point out the error in some of the reviews I've read.
