Customer Reviews for VEVOR Dry Diamond Core Drill 5"/127mm Dia. Hole Cutter for Concrete Masonry

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.

thank you makes my job way easier know.https://www.vevor.com.au/hole-saw-kit-c_11426/vevor-dry-diamond-core-drill-3-76mm-dia-hole-cutter-for-concrete-masonry-brick-p_010847462202

hey, easy to use and helpful thank you. website is easy too good quality and quick shipping, great pricing too, thank you. if needed i will buy more like candy. We love sprint car racing.

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.

REALY AWESOME THANK YOU VERY MUCH. IT WILL MAKE MY JOB WAY BETTER NOW . I WILL KEEP BUYING OF YOU GUYS .

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.

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.
