Customer Reviews for VEVOR 8 Inch/205MM Diamond Core Drilling Machine 3980W Diamond Core Drill Rig with Stand and Drill Bits,Wet Dry Core Drill Rig for Diamond Concrete Drilling Boring (Drill Bit Diameter: 4.25"/108MM)

I was pleasantly surprised with the quality of this product at the price point that it was sold at. I wasn’t expecting much, as the price of this product was what I would have paid to rent one for the day. This product exceeded my expectations and I’m sure it will drill many holes for me. I bought it for the expectation of maybe being able to use it two or three times and seeing how the cost to rent one for less than a day was the same as it was to buy it I figured I would give it a try. I do not drill many masonry holes, but I’m sure this will last me for years and meet my needs for when I need to drill masonry holes. The only short fall I found with it was the base was a bit narrower than it needed to be and was somewhat to keep it in the correct place anchored to the wall. But with that being said, it was a hollow block wall and I could not get an anchor in it as good as I would have liked so that did not help the situation very much. I would definitely recommend it for occasional use.

Drilled through cinder block, brick, and solid concrete without missing a beat! The motor had plenty of power, the bit shows little wear after 3 holes, everything worked just as it should.

Great Product shipping was fast to silicone valley, I Mounted to the wall and used an 8” Core bit I acquired and This Tool Did a great Job, I was amazed by the high quality of this product for such a great Price

My guys said it’s a great unit their only disappointment was it doesn’t have a two speed transmission.

Used this yesterday to core two 11.5\" retaining walls. Solid as a rock and the motor run very smoothly. I bought it because I needed to core a 7\" hole and my Hilti DD130 will not core larger than 6\". It's not as comfortable to use as the Hilti but it ran smooth and didn't bind. Best $300 I've spent in a long time. I thought it had died on the first hole but I had been pushing it hard and it tripped the reset on the side opposite of the switch. Slowed down a little (I'm impatient) and it worked great. I would recommend spraying some WD-40 on the post before use. It moved smoothly on the first hole but for the second there was some resistance to move on the post. After a little oil it was smooth again. For the price I expected it to be flimsy but it was more solid than the Hilti.

Core drill works great

Works great for core drilling ladder sockets in swimming pool concrete decks

How could I make a 6 inch hole?

This thing is built well. I have used it on 5 jobs now. The first was a horizontal drill. Holding any drill is tough when you are going through 8-10 inches on concrete. Words of advice: Get 4x1/2 inch tap construction to secure the drill to the concrete Don't drill your tap con within 1 inch of another hole or ledge. Don't use the tap con for more than 3 or 4 re-placements With longer bits to get them started bump the power on and off to get a secure ridge started. Always use plenty of water

Drill looks great. Lots of weight and visual quality. Drilled. 3 holes, then stopped working. Contacted customer service who worked with me daily to try and resolve. Could not resolve and was given 50% refund. later I figured out it was the ground fault protection that malfunction and had to bypass it. So quality is lacking but customer service was outstanding. I'm happy with the resolution.
