tool works great but took over 20 days to arrive due to FedEx screw-up; not Vevor's error. FedEx shipped drill set from California to Colorado to Idaho to portland OR, and finally back to Colorado.

After receiving product with many parts missing and messaging with Vevor, they sent me a new item which arrived complete. Drill came with 4 inch bit. We bought an 8 inch bit from Vevor and then an adapter separately to connect to the drill which is required and a quick connect water line adapter to connect to a garden hose. Once we had all of this the drill functioned very well. We drilled a perfect 8 inch hole through a 10 inch foundation wall. We used two large concrete anchors mounted through the center of the stand. But was a little wobbly at first until it the hole got started. We didn’t force it and let the bit slowly eat into the wall with light pressure on the crank. It took 5-10 minutes once drilling started to break through. Very happy with the result.

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.

For the price, this coring machine worked very well. I only dilled one 8" diameter hole through 10" of very old concrete and it work extremely well. Local contractor quoted nearly $1000 do drill this hole! It does not have all the bells and whistles on more expensive machines, but for the price, it did a great job. Since i only used it once, I cannot comment on durability, but it seems solid and well made. If you only have a few holes to do, i would definitely recommend this product.

This machine it’s Amazing 1 hour 30 core drills Doesn’t overhead It has its own Breaker in case the power ever goes off” I love it

Only used one of the cutters and no problem with it
