VEVOR Diamond Core Drilling Machine, 8in Wet&Dry Concrete Core Drill Rig with Stand, 750RPM Speed & 1-1/4" 5/8" Thread & Lifting Handle, 8in Drilling Diameter for Concrete Brick Block Stone, 2500W

Great little machine, and for only slightly more than it would cost to rent a comperable unit from an equipment rental company, I now own it. Not sure what I'll need it for in the future, but it very cleanly cut a 4" hole through my basement wall, and it made light work of it. Super powerful and easy to use. I spent more time stopping to check how deep I had made it because it was cutting so fast.

Full disclosure- I have never used a core drill before.I needed to drill a 6” wide hole in a 10” thick concrete wall. All of the rentals (Home Depot, etc) were missing pieces of the mount/drill/you name it, and they were charging $200+ for a single day’s use.I found this drill and purchased a SALI 6” diamond tipped core bit. The instructions were somewhat lacking but eventually I got it all set up. I ditched the screws that “stabilize” the base and used 4x 1/4” diameter 4” long tapcon screws to anchor the base to my vertical wall. This thing is LOUD and honestly it kind of made me nervous. Use eye/ear/hand protection 100% of the time as well as a continuous(ish) stream of water to keep the tip wet/cool, it’s absolutely necessary. It took about an hour and a half to core through the 10” wall. Removing the concrete core piece from the core bit was INCREDIBLY difficult. I ended up having to buy a SDS plus chisel to completely fracture the piece of concrete for hole #2.Once I got the bit empty of the concrete plug I moved onto hole #2. This 2nd hole was unfortunately 9.5’ high and what turned out to be 14” thick. It was not a good day when I figured out it was much thicker than the first wall. After an hour and a half (and throwing my breaker a few times), I made it through the wall. The drill performed 100% the way I hoped it would and it was immediately thrown in the trash can after. This was honestly one of the most dangerous things I’ve ever done and I’ll never do it again.But as for the product- 10/10. Thank you for not making something that hurt me.Recommendations from my experience:- Mount the base to the wall using 1/4” tapcon screws at least 4” long- Use water (I used a generic spray bottle) throughout the drilling- Be prepared to spend an hour or more trying to remove the concrete plug if you have to drill more than one hole- Hire someone to do all of this because it’s incredibly dangerous

Pretty solid core drill, maybe a little under powered. Drilling 2”-3” holes isn’t a problem at all with this drill!Pros:-Cheap, I paid $206 for this drill.-Lightweight, easy to carry-ReliableCons:-Short, a real pain on the back leaning to crank the handle.-Water hose connector is trash, cut it off and replace it as soon as you get it-Drill base is very small which makes it difficult to level.

This drill works great. I am a first time core driller and was skeptical of the low price point compared to name brand units. I purchased a separate 8" bit and drilled thru 9" of concrete and rebar with no issues. I took advice and drilled very slowly especially when I detected the rebar. I also used 1/2" tap cons to fasten the drill to the concrete which I HIGHLY recommend. The drill itself is of high quality and comes with everything you need.

This is not a toy. I saw the review of the guy getting injured with one of this equipment and I just want to say that, if you are not sure about the property operation of this machine, get someone else to do the job. Make sure your fasteners are properly secured and the machine is properly aligned, put yourself as far as you can from the machine in case it jammed and wear the right protectionThis machine does a pretty good job and is definitely worth the money if you do not need to core bit every day, if you need something for daily use get a hilti or something else because this toolIs good for occasional usage

The drill and drill bit worked beautifully and as described by the Vendor. The water line quick coupler attachment was of a strange size that matched nothing I could find in several stores. I had to purchase my own parts to improvise to get mandatory water supply to drill. The mount stand was made of lightweight soft metal. When turning screws into pre-threaded holes, you could feel the grinding of metal, eating up the threads. Hard threaded inserts could have possibly been installed and the use of harder steel screws. After drilling a 4.25" through 8" block, the bit teeth looked like it was barely used. The outside metal of the bit, showed paint removal and scratches on the bit. This was normal. If it wasn't for the water supply issue and the inferior Stand Mount, this would have been a great product to keep.

I used this today to drill 4 holes through a stone foundation in PA. I have no idea what the exact name of the stone is but there' a reddish field-stone that is so hard it's like granite and I was able to do the holes 100x easier than the old way I would have done it which is to use a hand-held core drill. This was so much more pleasant to turn a crank rather than hold the drill and safer too.One imperative tip for anyone using this core drill is to fasten the drill base to the wall or floor using multiple bolts. If you only use one anchor it will slightly deflect while you're drilling and the bit will bind. With multiple anchor bolts (I used three 3/8x4" tapcon bolts) the base will not deflect and the drilling is very easy. If your wall is greater than about 18 inches thick you will need to stop mid-way and add an extension. The bits tend to cold-weld to the drill spindle and the way to fix that is to put a giant adjustable wrench on the core drill bit and hit it hard with a drilling hamer to shock it and it will unscrew. It needs to be a really hard hit, plan on the wrench to go flying during the process but it will separate the bit from the spindle.

I just finished drilling 10 6” deep 8” diameter holes in the concrete. Didn’t use the supplied bit as it was too small for the job but the drill itself worked great. Durable and reliable. Very happy with the VEVOR brand specially for the price

Qualidade preço bom

J'ai été agréablement surpris par la qualité du matériel. Le seul défaut est l'absence d'une notice claire mais, finalement, le montâge est très simple. Il faut simplement prévoir un ou deux goujons d'ancrage pour la platine de fixation au mur. Les quatre vis sur la platine servent uniquement à la mettre bien à niveau (ou à pencher un peu la machine pour réaliser une pente légère). J'ai percé un trou de 20 cm de diamètre dans un mur en pierre épais de 50 cm sans aucun problème. Prévoir éventuellement une rallonge car il faut enlever presque 10 cm à la longueur effecitve de forage de la carotte.

Machine impeccable ... Dommage que le sais pas faire de biais... Un peu lourde aussi

Cumplió con la expectativa de perforado y calidad en el producto

Ottimo prodotto!Forato un muro da 60 cm circa in pietra(con aggiunta di prolunga) senza problemi.Molto soddisfatto!
