Customer Reviews for VEVOR Diamond Core Drilling Machine, 8in Wet&Dry Concrete Core Drill Rig with Stand, 750RPM Speed & 1-1/4" 5/8" Thread & Lifting Handle, 8in Drilling Diameter for Concrete Brick Block Stone, 2500W

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.

I used this to drill 6 4" holes through a 18" thick rock wall to help drain a parking lot. I have to admit I didn't have much hope for the bit that came with the machine. But I will admit my fears were misplaced. The flexibility of not being stuck to a stand allowed me to position the drill on an angle. The bit lasted all 6 holes without having any of the "teeth" break off. And other than having to reset the saftey gfci switch numerous times, it kept tripping because of fractured peices of stone making the bit get stuck, this drill worked amazing well and at a really reasonable price point.

I was skeptical of a core drill at this price point but I needed one in a hurry so I took a chance. It works great and has lasted so far. I bought another one for my crew and again so far so good.
