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.

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.

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.

The core bit was good prices and delivered quick but the pilot bit was shorter than the outside core making it impossible to start the hole. I had to grind down an existing sds bit to make it fit so I could get the job done. Very dissapointing.
