Item are very good and really good quality but it doesn't come with an extender for it or a bit. Now I have to go look for one

钻头就不用多说什么了。根几百块买的钻头效果一样。用的时候记得加水尽量不要干钻。我准备陆续把这些钻头都买齐。以后干活方便好多 评论一定要一百个字以上折磨人啊。。。。。。…………………….……………………………………………………………………

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!

It works great drilled in some posts holes into bedrock. Can put it in your normal drill, I use that hammer drill which is not recommended for coring holes.

Aangeschaft om gaten voor spots te boren in mijn oprit tegels. Is goed gegaan. Mooi dat er drie aansluitingen bij zitten
