Customer Reviews for VEVOR Core Drill Bit, 2.5" / 63.5 mm Diameter 5/8"-11 Threaded, 9.5" / 241.3mm Depth Diamond Dry Coring Bore Tool with a Pilot Bit & 4.5" Blade, Masonry Hole Saw Bits for Hard Concrete Brick and Block

Used for drilling holes in 10” concrete including rebar. Worked well - kept wet. Can’t comment on long term use, but for price seemed good value.

It is well made, ate up the concrete slab using a wet core drill. We went with a handheld model, which works great if you have a lot of experience with large drills.

Was told by the guys in the field that the bit cut good, no complaints

Came promptly and worked great. Considering most of these bits cost over $100 I was curious how it would do. Had to drill two holes through brick veneer and cinderblock foundation and it worked great. I definitely recommend this bit.

great customer service love vevor will keerp coming back for more products fast shipping !!!!!!!!!!!!!!!!!!!!!

The unit I received was faulty. The screw that holds the pilot bit was stripped out, so that was useless. However, after I made a template in a piece of plywood, the core drill worked great to bore the hole I needed. I am impressed with it. I would order this tool again if needed.

You will need to visit Amazon and purchase an adapter to use on Vevors stand up core drills* That being said, this bit cuts right through a concrete driveway no problem with rebar. Took maybe 3-5min per hole. It can be tricky to get the hole started because of the size of the bit. I found that tapping the bit lightly a few times against the driveway while spinning to start a new hole helped a lot, if you just go straight for it while the bit if spinning and try and hold it down to cut a new hole the bit and drill will start to wobble and go crazy on you.

Bought a 4 inch and a 3 inch. Used the 3 inch today and on the second hole two chunks of metal broke off. Also the set screw for the guide bit kept coming loose. A little disappointed as I had 2 more holes to drill.

Works great but I had to buy an adapter from Amazon to use it on the core drill I brought from Vevor.
