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.

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

Cutting into granite

Gets the job done
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.

Cuts big holes in concrete
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.

2.5" core drill bit
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.
