Extremely disappointing!!!! Got fan installed, it worked for 3 hrs with not much air displacement. Next morning fan won’t move it just twitches! Recommend not buying this item!!!

Diamant is goed, maar boor zelf is waardeloos Houder voor sds ook te zwak. Dit is na 5 gaten in baksteen

De kernboor ziet er degelijk uit. Echter hij past niet op de onlangs aangeschafte kernboor van Vevor. Je zou verwachten als je iets koopt van dezelfde fabrikant dat het dan past. Ook geen adapter beschikbaar. Dan maar besteld bij Aliexpress,

La carotteuse à l'air de bonne qualité La mèche commandé en plus avec dans le même colis je suis très déçu, le pas de vis ne correspond pas à la machine Domage el me servira à rien

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.

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.

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

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

Bought the 2 1/2” core drill bit The pilot bit was not straight. The core bit did not fit the 4” vevor core drill. So I had to use a supplied SDS shank that hold the 2” bit as well as the pilot bit in a hammer drill. First the Allen screw came out which hold the pilot bit. Then the the 2” bit snapped off the SDS shank. Breaking the threads off. Which made the whole set up worthless. The 2” drill is only held on by 3 threads! I was drilling through a non reinforced concrete wall.
