This is a very nice rugged drill but the part of the drill that connects to the drill bits is very unusual. It is larger than almost anything I could find in the way of drill bits. Almost all of the drill bits offered by Vevor are NOT compatible. If you look very closely, there are a couple, but nothing in the size that I wanted. The drill bit that I got is excellent, but it can not be used with this drill. I had to put it on my old hammer drill to get the job done.

Don't buy it, I drilled one hole in concrete floor , half the teeth were gone. I drilled the second hole in a concrete block wall, got 1/2 way through all the teeth were gone.

The set screw for the guide bit absolutely will not stay in under any circumstances. Loctite doesn't work, pre drilling the hole so the guide bit is just a guide doesn't work. The core bit itself does work relatively well. 3 holes through a single layer of brick and it's slowing down substantially, though. Don't expect it to last a long time, but I think the price sort of reflects that.

It wobbled so bad I could not get it to start cutting the hole. I eventually gave up and drilled around a 41/4 hole with a drill bit and busted it out.

The SDS plus shaft's threaded insert broke in half, inside the bit, rendering the part unusable after only 4 inches of coring. The entire work day paused.

He solicitado la devolucion pero no la han tramitado

I never received the item I bought. They refused to refund my money. RUN!!!!

Je suis très déçu car au déballage, je m'aperçois que le trépan que j'ai acheté en même temps que la carotteuse n'est pas compatible !!!!

Did not receive

Do not recommend them based of terrible support alone. Its like pulling teeth to get a replacement product when 1 comes damaged.
