Does the job, but arrived damaged
Arrived damaged & missing pieces, Vevor did little to help. Poorly packaged & broken open, item was bent and the drill bit needed a $40 adapter to work with Vevor's drill (they don't tell you that & they don't sell the adapter) the only thing Vevor did was offer a small refund, too little & not a solution!
Brian Elkins Brian Elkins

Drilled one hole with it. Well no I didn't even get one hole with it drilled. It started to fold in on its self had water to cool it wasn't drilling to fast hardly any pressure at all. Wouldn't recommend to any one..
Smitty Smitty
Mr
This is a very nice rugged drill but the part of the drill that connects to the drill bits is very unusual. It is larger than almost anything I could find in the way of drill bits. Almost all of the drill bits offered by Vevor are NOT compatible. If you look very closely, there are a couple, but nothing in the size that I wanted. The drill bit that I got is excellent, but it can not be used with this drill. I had to put it on my old hammer drill to get the job done.

Disposable bit
Cored 2 holes. Broke teeth on the last. Swells so you can get all the core out of the bit. Disposable bit.
KUMARAN SRINIVASAN KUMARAN SRINIVASAN
Great customer service
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.

Well, not really sure how good the bit is, because when I got it out of the box to use it, it only had a 5/8" arbor and won't fit the vevor core drill i bought.
Daniel Howard Daniel Howard
Homeowner
Never used this type of core drill. It was very easy to use,went through 8 inches concrete block dry and with not much effort. Very pleased, I needed this hole drilled for mini split ac and it was perfect for the job.

Core bit
Worked better then some high end bits I have used. Drilled a 5 in core with no issue or hiccups including 2 -1/2 rebars definitely shocked how good it worked for the price I didn't have the best expectations. But I was wrong
Andre Andre
Works awesome so far . I have 4 more holes to core out of 8 . My slab is 4 - 6 inches thick .
Reasonably priced with quick shipping . Im excited ! My fence can now be started . It cut my concrete effortlessly .
