Broke During 1st Hole
I thought the bit was exactly what I needed to put 6-8 holes in the concrete. I got about two inches down and the head broke off.. I very well could've hit rebar, but the packaging says it has "5X times life in rebar" yet it couldnt last one hole. I would not recommend.

I purchased this drill bit for my old Hilte hammer drill we had a water leak under the slab. I was able to get the slap open and find & stop the leak. The drill bit was just what we needed. It stayed sharp and drilled out a 1 x 2 ft opening in the concrete slab.

Worked well
Drilled down through 9 inches of concrete very well. As expected, had to bang on the drill when the bit ran into gravel/stone in the really old, really hard concrete but this bit did the job. It's all I could ask for.

Great value for money. Gets the job done every time.
