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.

I used it to core through a 150mm slab for shear bolts. No problem in drilling, except keeping the bit vertical.

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.

Used the drill to cut two 50 mm holes, 150 mm deep in concrete. Worked a treat, had more than enough power. Only drawback was the pipe supplied to water cool the core cutting bit was a bit loose and kept coming off the built-in hose connector under pressure. Other than that did a great job.

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
