Customer Reviews for VEVOR Diamond Core Drill, 1800W 4'/110 mm, 1700RPM Variable Speed Core Drill Rig with Portable Case, Handheld Drilling Machine for Porcelain Ceramic Tile, Marble Brick

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.

I originally planned on renting a core drill but decided to try this one as it was cheaper to buy it than to rent one. It arrived in its own case with extra brushes and all the components needed to run it. I attached an 18" long and 4" in diameter bit to it and began to drill.I drilled from the outside in and was initially nervous that at some point the bit would catch and rip the drill out of my hands, but after it eventually caught I realized that this drill was designed so well that when the drill bit did catch it was a smooth stop and didn't jerk or rip it out of my hands.It took me about 2 hours taking breaks to rest to drill through the 10" of cement and rebar, the drill never got hot, never skipped a beat. I am very impressed with what you get for the price. I think this will be a tool I will have around for a long time and am confident it will work when I need it.I would buy from this company again without hesitation.

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
