Customer Reviews for VEVOR 160MM Diamond Core Drilling Machine 2180W Diamond Percussion Core Drill Wet & Dry Handheld Diamond Core Drill Heavy Duty for Diamond Concrete Drilling

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.

I am in the process of adding a shower stall to a downstairs half bath and needed to "dig" a six foot drain pipe trench in the foundation. This probably is not the best tool to do that, but I gave it a try. I successfully drilled numerous 3" holes to create the trench and used the 4" bit to dig out space for the shower trap with no problem, this thing is rugged. I did let the drill cool down after drilling every three holes just to be on the safe side. I hit rebar several times, I thought that might eventually dull the bit but it didn't seem to. I did hit a copper water pipe in the foundation, at least the drill was helpful in getting access to the damaged pipe. I definitely felt I got my money's worth out of this drilling machine.

This product was well worth the money and I would buy it again if I needed, it worked great

Excellent price and well made. Right out of the box cored 5 holes through 2” blue stone and granite. Comes with quick disconnect for hose connections. Highly recommend.

The machine overall is great, one thing I'd change is the plastic handle on top, it should be metal...............................................
