Customer Reviews for VEVOR Core Drill Bit, 1" Wet Diamond Core Drill Bits, 14" Drilling Depth Concrete Core Drill Bit, 5/8"-11 Inner Thread, Laser Welding, Diamond Wet Coring Bit for Concrete Brick and Block

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.

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.

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

Reasonably priced with quick shipping . Im excited ! My fence can now be started . It cut my concrete effortlessly .

So far I’ve cut 2 holes 6 inches deep in a granite monument and it worked great.

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.
