Customer Reviews for VEVOR Diamond Core Drilling Machine, 4in Handheld Wet Concrete Core Drill Rig, 1100-2400RPM Two Speed & 1-1/4" Thread & 2 Bubble Levels, 3-4in Drilling Diameter for Concrete Brick Block Stone, 1500W

Very good quality . Highly recommended! Very good price for good product!

I only used this for about 40 minutes, but it did the job well, to bore 2, 4.5 inch bore holes through about 6" of concrete in 20 minutes each. My only complaint would be that the 1 1/4 - 7 output shaft was not compatible with the cheap diamond coring bits they also sell at Vevor, which have a 5/8 inch-11 female connection, so, to use this drill with the diamond coring bits they have on their site, a $30 adapter had to be purchased on Amazon (not available on Vevor at the time of my purchase). Using that adapter, the drill + 4.5" diamond coring bit worked great, though the adapter didn't allow for the water valve to be used in the drill, so I basically just used it as a strong drill and used a garden hose to spray into the hole instead of through the drill. It wasn't a big deal in my situation. I wish they sold 4.5" diamond coring bits with a 1+1/4 inch - 7 thread on the Vevor site, so this drill could be used as intended with the water jet/valve and without an extra adapter. I think those types of diamond coring bits are sold elsewhere, but at much greater cost than they would be if they were on Vevor's site.

The Item worked great and was delivered very fast. I would recommend this item.R. Barstow

Looks great, need a list of available drilling attachments, sizes and pricing. I can’t wait to use it, have first job through a 12” reinforced concrete block cistern John W.

We purchased this to drill some 4" and 6" holes through 6 inch thick concrete. The drill tackled the job with no problem, i would definitely buy this brand again. we drilled over 100 holes and the drill held up great.ChuckA&S

It might not be as big as some of the ones I have used in past, but it works just as well. I was impressed with it. Powerful core drilling machine and portable case. If you want my advice, buy it.

The only complaint I have with it is water adapter would not withstand my house's (city's) water presser (it was too high) and the tubing would pop off, then the threaded adapter would disassemble it self. The solution was not to close the water valve at the drill motor. I was very fast going though the 11 inch brick foundation. about 10 minutes or less.

This is the whole package, right sized Auber, wet connection, automatic surge kick out, and powerful motor to take it home, just hope they are good about repair parts since I got it hung up onetime and damaged it when it spun out of my hands, but a few tywrapes later had it running again, I’d have to say it’s got heart.

I bought the drill with low expectations but when I got it I was surprised it was built well I had to drill a 4.5 inch hole threw 10 inches of concrete and it drilled threw with out a problem the only draw backs are does not have a varyable trigger on or off makes it a little hard to start the bit into the concrete at full speed and the resettable circuit braker on the side of the drill popped once and had to reset it but other then that the drill is amazing for the price

Worked like a gem! Started smoking initially, but did an amazing job drilling four holes into concrete with no issues.
