I used the 5 inch bits mostly to remove rock for underpinning. The bits aren't as heavy as other brands bits but they deliver non the less. I cored hundreds of holes in front of the walls and under the walls. The bang for buck is not even comparable with any other bits I found on Amazon. The price Vevor is charging for core bits is so low, I could buy 5 bits for the same price of 2 Sali bits. And the Sali is a discounted bit! The bit works best with constant water flow expecially on your first hole. If you don't have water running through your drill the slug with stop the bit no matter how strong the drill motor. I was coring through depths up to 20 inches of rock. As you can see in the pics, I attached my drill to my excavator. Plus I added a Pic of one of the 5 foot sections I cored out for the underpinning. These bits work! But I would advise buying an actual core drill. I have a heavy duty Milwaukee hammer drill and it still isn't able to properly core holes. Vevor sells core drills that are pennies on the dollar compared to ANY other dealers!! The down side, when something breaks it takes weeks to get replacement parts. Also when I first started ordering their bits they would come within a day or two. No they take up to a week to deliver. All in all these are the best bit for the price! Not even close. Tried to add pics but their site won't upload them.

Wie immer, zu diesen Preis unschlagbar, Top

Hatte mir die 127 Bohrkrone besorgt um 25cm durch Estrich und 50cm durch Sandstein zu bohren. Verarbeitung ist präzise und das Bohren (mit Kernbohrmaschine) hat hervorragend funktioniert. Vevor ist großartig!

Muy buen producto y a un buen precio …

Top alles bestens

Tout est dans le titre 😀 2ème achat chez Vevor, la qualité est top, le rapport qualité/prix est du master game => chapeau bas, Vevor !

I needed to cut two holes in the concrete floor for a toilet and shower drain. Floor thickness about 4 inches, and super solid, 75 year old concrete. This drill did the trick. My only precaution is that once the main circular bit starts getting a bite on the concrete, REMOVE THE PILOT DRILL!! It's pretty tiny and deflects easily, so it will follow a different path than the core drill, and will likely break. Also had to take a break about every inch or so and chisel out the core.

The pilot bit is too short to fit through the end of the core drill. It's very hard to get started without "wondering". The pilot bit is also of very poor quality.
