4.25" Wet only Core Drill Bit 4.25" Wet only Core Drill Bit
4.25" Wet only Core Drill Bit
The absolute best price on the web. Don't waste your money on the expensive Milwaukee, Dewalt, or bosch bits. I get the same amount of drilled holes out of Vevor's bits as I do with the expensive ones. Approx 10-15 perfect cores, throw it away and buy a new one. Works great and gets the job done.

Useless. Doesn't work with the Vevor Core Drill I have as the thread sizes are different and Vevor customer service is even more Useless.

Buy something better
Usually I love their stuff but..... If you can afford to get something better, do it. This thing destroyed itself going through one 8 inch foundation wall in my basement for a two and a half inch hole. The bit literally shredded and the tips ripped out. Wrenched my hand all over the place. Definitely do not recommend.

Idéal pour les petits travaux à la maison
Utilisé pour passer à travers un mur de briques de 35cm. J'ai eu besoin d'environ une heure pour passer à travers et la coupe est très propre. Devant faire un trou légèrement incliné, j'ai d'abord foré avec le mèche seule suivant l'angle désiré, ensuite commencé le carottage avec la mèche + carotte et a partir d'une dizaine de centimètres, j'ai retiré la mèche pour continuer jusqu'à la fin. Sinon la mèche peut accrocher les gravats.

Does the job, but arrived damaged
Arrived damaged & missing pieces, Vevor did little to help. Poorly packaged & broken open, item was bent and the drill bit needed a $40 adapter to work with Vevor's drill (they don't tell you that & they don't sell the adapter) the only thing Vevor did was offer a small refund, too little & not a solution!

Drilled one hole with it. Well no I didn't even get one hole with it drilled. It started to fold in on its self had water to cool it wasn't drilling to fast hardly any pressure at all. Wouldn't recommend to any one..

Mr
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.

Disposable bit
Cored 2 holes. Broke teeth on the last. Swells so you can get all the core out of the bit. Disposable bit.

Quality is not as good as I would have liked, but reasonable for the price. I haven't used it yet. I hope that it does the job.
