Customer Reviews for VEVOR 8 Inch Diamond Core Drilling Machine 3980W 750r/min Diamond Core Drill Rig with Stand and Tools Wet Dry Core Drill Rig for Diamond Concrete Drilling Boring (205MM)

Cored a 4" diameter hole through 10" of concrete and precast deck without an issue. Make sure to keep it well flooded with water - if the diamond loads up you can overheat your cutter.

Just got the 6 in version. The thread to the drill is 1-1/4 7tpi in spite of the 1/2 BSP in the spec, so that is the good news. The supplied drill is a couple of inches shorter than standard, so it would make it through a 12 in wall, but not a 14 in like the standard drills. The column is JUST long enough to accept a standard drill without having to block the base off the surface. The machine is NOT variable speed. It has an on/off switch only. Not the end of the world, but be aware. The label on the motor says 110V 50 Hz, so clearly a product made for the China Market and only slightly reprocessed (it has a US standard plug). It is a universal motor, so the 50/60 Hz thing should not be an issue, but 120V will probably be pushing it a bit. The flip side is that it should be happy on a fairly long extension cord and since it draws 20 Amps, that may be a good thing. Haven't had a chance to drill with it yet, but it looks workable and it is about half the weight of my 10in drill, so a lot easier to horse around for smaller holes. I got it for the 1" to 3" stuff because my big drill doesn't run fast enough to be efficient with small drills and I think it will be fine for that, but the whole setup is pretty light for anything bigger than about 4 inches. My big drill is a predecessor to the Bluerock line and it has been a beast, but it is heavy.

good product works better than expected and price was good

Good buy for the$$$

Drilled two holes thru 1 ft. Brick walls! Holes should be lined with sdr 35 pipe, schedule 40 will not quite fit! The drill performed well though you can smell thos brushes going bad! Everything is low quality but it does work! I used lag shields and bolts to anchor the base for horizontal drill. The hose connector is a weird size I just duct taped it to garden hose! The motor runs a bit fast. I bet with a bigger bit it can get real hairy! The cord unfortunately did wrap around the advance lever, recommend putting the lever on the opposite side to avoid this unfortunate circumstance.Definitely not a knock off of a name brand but the drill worked fantastic all things considered! Thank you china for producing this, the rental yards here suck so this was my best option! Drilled my holes for much less than hiring out. And now can drill more when I need!

Product works great. If you think you need this keep in mind it is for very advanced DIYers; not this product in particular but almost any core drills really.

Good machine and strong and easy to used

I needed to core drill some holes in a concrete retaining wall and looked at renting a "hand drill". I knew that with the number of holes I needed to drill that it wouldn't be a 1-day job. I did the math and decided I would buy this tool instead of renting. It arrived in 2-days (thank you Prime) and pulled it out of the box. The packing for such a heavy tool is poor, at best, and the power was actually damaged. I needed to use the tool the next day, so I made a temporary repair to the cord and used it. It works great and the mounting rig is a HUGE backsaver. Instead of lugging the drill head and bit for over 30 minutes (each hole) I was able to get comfortable and sit while the drill did the work. It has all the power needed to drill a 4.25" hole if you have the patience to drill into concrete - which is not a quick process. I still have a few more holes to drill, but so far I am extremely happy with this tool and the overall purchase.

Good product work perfect

Overall a nice product. Packaging and initial setup took a little effort and I think could've been done better. The fitting fit the supplied bit won't accommodate smaller cutting bits.
