Great quality core drill bit. Problem is, I can't use it. I was unaware that when I bought it I needed an adapter to mate with my VEVOR core drill.

Loved it. It came with an adapter for SDS PLUS which was great. The set screw fell out and the small center drill bit got stuck inside adapter forcing me to cut it off with a grinder and continue drilling You should not use hammer drill and instead use fast flowing water in drill mode only.

I need to make a hole in an old, thick foundation. This drill worked beautifully. Quality of the drill was excellent and I expect to be able to be it multiple times without it wearing out.

The absolute best price on the web. Don't waste your money on the expensive Milwaukee, Dewalt, or bosch bits. I get the same amount of drilled holes out of Vevor's bits as I do with the expensive ones. Approx 10-15 perfect cores, throw it away and buy a new one. Works great and gets the job done.

I have a Vevor 4-in drilling machine and bit great product and I wanted to use this 5-in bit and ordered. It came quickly. I opened it. The product looks very good but unfortunately it was not compatible with my 4-in machine. So please be careful while ordering. This is not compatible with a 4-in machine and you might have to buy a separate drilling machine for this. However, I contacted customer service and they were very great in processing the refund. I haven't used the product but the bit looks pretty solid and it also comes with a free blade.
