Klantbeoordelingen voor VEVOR kernboor, 203 mm diameter, 356 mm boordiepte, 1-1/4 inch-7 binnendraad, zeer nauwkeurige lastechnologie, natte diamantkernboor voor gewapend beton, baksteen en metselwerk.

A broca central é mais pequena que a exterior, logo impossibilidade de servir como centro do furo. Usei outra solução para conseguir centrar a broca, furou muito pouco até perder toda a eficiência

Deze boor besteld om 2 gaten in beton te boren. Centerboor steekt er niet uit dus was niet te gebruiken en de boor zelf was kapot na 10 cm boren.

I purchased this Corvette the same time I bought my new drill because the bit that comes with the drill was only 4 inch and I need 4 1/4 so I ordered this 4 1/4 drillbit But to my surprise, it landed here and it doesn’t fit this drill. It’s for a different type again. I’ve tried multiple times to get a hold of you guys and the way you have it set up to connect is Ludacris I’ve purchased many things from Vevor as I really like your products however, lately they’ve been going downhill The biggest concern I have is reaching out to you people this thing about tickets and all the stuff you’re talking about I ain’t got a clue and I’ve replied to you. I’ve sent you all the information I can send you and you still act like you didn’t even get my message that you want me to send all the stuff again I’ve sent it to you two or three times. Very disappointed and if we can’t get this solved soon, I will completely stop by in Beaver and I will encourage my friends to do the same because I will start posting on the Internet that problems I’m having Sorry, I hate to do that but I hate to be screwed around with Steve

Se casse rapidement. Je ne recommande pas ce produit et je déconseille fortement de l’acheter. Même la tige intérieure de la cloche s’est pliée après très peu d’utilisation, ce qui montre que la qualité est vraiment mauvaise.

le foret et trop petit le truc est inutilisable

The pilot drill is too short, so I was not able to use the core drill without an additional pilot drill.

This core bit is not useable due to the pilot bit not being long enough to lead the bit. Bit will not cut masonry.

The pilot drill is shorter than the core drill making the entire thing completely useless misleading not as shown in the picture

The core drill bit failed after one hole. The weld failed. I have picture but cannot get it sent to you.

You may be thinking of purchasing this as a cheaper option, but it's not worth it. The bit didn't drill even 1/4" deep before the threads on the arbor broke, the threads on the pilot set screw broke, the pilot bit is way too short. The metal is too soft for the use it is supposedly designed for. Terrible quality, I couldn't even drill out one hole.
