Customer Reviews for VEVOR Core Drill Bit, 63.5 mm Diameter 11 Threaded, 241.3mm Depth Diamond Dry Coring Bore Tool with a Pilot Bit & Blade, Masonry Hole Saw Bits for Hard Concrete Brick

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.

Looks good can’t wait to use it yet. Got no project but will let my friends knows. Just in case they needed one for their home .

Impeccable pour passer une gaine de 40 dans une dalle, prévoir un bon perfo ( 7 joules minimum car essayé avec 2 joules pas concluant) Très bon résultat, merci beaucoup

Worked much better than expected. Definitely worth the money. Received within 3days. Drilled a perfect hole through my brick wall.

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.

All good - wanted the 1.25 dia thread instead of the 22mm which seams to be the standard now in metric-was very pleased to find this incn size — will need to look or make adapter to use 22mm core drill bits in my 1.25 machine

The guide bit is useless. Built a rig to line it up. Overall, good value for the money. Have drilled 4 holes through 3 layers of brick each and it's held up well.

funziona perfectamente l'unica pecca che la punta si svita sempre

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 perfectly drilling my 10” thick brick walls
