Customer Reviews for VEVOR Dry Diamond Core Drill 3"/76mm Dia. Hole Cutter for Concrete Masonry Brick

I bought this with the intention of drilling a single hole through a hollow concrete block for a dryer vent. For that purpose, it worked like a charm. I was able to get through the front half off the block before burning out my cheap 20 year old drill. Another better drill finished the back hole.I saw one review that said the drill bit was too short. That was not true for me.I cannot speak to the longevity of the bit, but for the single hole I needed, this was a great value.

We were boring through concrete. This bit make it easy and effortless!

Works great. Use a wood template. Duh.

Great looking drill bit, especially for the price. Teeth a little thinner than expected, but will give it a try.

Good product would recommend to anyone

I’ve not used the coring unit yet, but that free 4” Diamond disk is dynamite; I’ve used it 3-times now, very impressed.

I used this to core a hole through a solid Concrete Basement wall for a Split Unit A/c.....took about an Hour...with a smaller Bosch Rotary Hammer......I only used the Hammer feature occasionally....and Drilled it Dry...Excellent Product!!

The core bit cut though the brick without much difficulty. The pilot drill however does stay lock into the adapter regardless how hard I tightened the hex screw it always wobbled free. Only used it once so no real review on longevity or durability.

Worked perfectly and even cut through the steel reinforcing rods embedded in the blockfilled concrete walls . Top product , even the tradies were impressed.

This bit doesn't work with drills sold on this site. The receiver on this bit is only 5/8" and the drills sold on this site are 1 1/4" arbor.
