Customer Reviews for VEVOR Diamond Core Drilling Machine, 10in Wet Concrete Core Drill Rig with Stand Wheels, 750RPM Speed & 1-1/4" Thread & Lifting Handle, 10in Drilling Diameter for Concrete Brick Block Stone, 2500W

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.

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.

The drill was great until it quit working. I contacted the seller and after me sending proof of it not working they very quickly resolved the issue.

Good machine strong

I liked it very much used to repair bridge

The core drill worked very well. It had plenty of power for 4" cores drilled to depths of 8 to 12 inches.I liked the power switch location and operation. The core drill and frame is light and easy to carry.The included water supply hose is flimsy and should be replaced with a higher quality hose. The wrench inset on the stem is narrow. We had to grind down our wrench to fit the narrow inset.

Fantastic performance . 19.8 amps. Used a 6 in. core bit and it handled no problem.

Equipo robusto, se esta usando y responde con potencia

Dont know how long it will last. Did 6 6 inch holes just fine. Cheaper then renting.

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.
