It’s an amazing package for the price. This comes with drill stems for industrial drills and home drills alike. The center bit can be replaced with a hardened concrete drill and this cuts well into the older hardened concrete to make bolt down holes for anchoring heavy vibration equipment. If you’re doing a job with some serious concrete to get thru this is a great bit. I used it to drill multiple 4.5” deep holes to anchor the weight train for an elevator and it worked perfectly.

Buen producto, ayuda a resolver situaciones y proyectos.

Fast shipping and worked great.

Didn't used it, but looks good, it's nice to have different options for different drills, hope it will cut concrete

Got this to put a dryer vent through my concrete foundation so I didn't have to rent a core drill. Worked great with my dewalt sds plus hammer drill. Took somewhere betweet 5-10 mins to go through the wall. For the price you can't beat it. Would reccomend.

GREAT VALUE WORKS WELL

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
