Recenzje klientów dla Wiertło rdzeniowe VEVOR, średnica 38 mm, głębokość wiercenia 241 mm, gwint wewnętrzny M16, wiertło diamentowe do wiercenia na sucho z 3 adapterami, wiertło prowadzące, klucz imbusowy do betonu zbrojonego, cegły, muru

The center pilot bit is too short and does not protrude out the end of the hole saw. I did try and pre-drill the pilot hole without the hole saw and found the hex screw would not stay tight in the arbor, so the pilot bit is basically useless. While the kit comes with 3 adapters, the threads are very loose fitting and the SDS Plus in particular only had a small portion of the threads engage inside the hole saw. I'm surprised it didn't strip out. It seems like this "KIT" is really just a bunch of random pieces they threw together and are not specifically made to fit together. While the hole saw did seem to cut through the masonry block fairly well at first it became less effective near the end of the 8" deep hole. If you only need this item one time, don't need the pilot drill and are sure there is no rebar then the price is good for a DIY'er. Just don't expect to put this tool in your kit and use it reliably in the future.

Attrezzo di pessima qualità usata per 3 fori in un muro non di cemento armato, la carotatrice si e rotta.

La punta si è disintegrata a metà durante la foratura di un condotto in cemento. Anche se si presentava bene e con tutti i suoi accessori Il costo basso mi aveva comunque già allertato. Ideale solo per forare al massimo dei mattoni con un po' di cemento

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.

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

produit visuelemnt de bonne qualité, le soucis c'est que le foret centreur est plus court que la carotte,, tu as interré de bien tenir ton perfo pour faire mordre dans le beton,,

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.

Purtroppo il prodotto non era descritto. Per cui ho fatto degli errori nell'acquisto della punta diamantata che per le dimensioni non corrispondenti non si avvitava. Ho dovuto acquistare un adattatore e fare alcune modifiche. Non sono soddisfatta. Questo genere di prodotti, specie se provenienti da paesi esteri, dovrebbero essere corredati almeno di una descrizione (anche in inglese), infatti si può incorrere in errori specie se di vogliono abbinare degli accessori.

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