Review: Hi all you guys and girls out there in, i need to drill a hole in concrete land. I got this bit and it bores a hole in concrete quicker and easier than anything else i have ever tried. I put it in my Bosch roto hammer and it was like a new species of drilling was discovered. I now present to you, BOREASAURUS. The most capable of the drilling asaurus. Special thanks to the desertcart team and the delivery people as it was delivered fast, and on new years eve, when most people had time off.
Review: I manage a manufacturing company and I have workers who are like the gods of destruction. Walls are always the first victim an I needed to bolt down some heavy duty guards as I wanted to stop buying dry wall and patching up the walls... I found this drill bit for my SDS plus hammer drill and started my work. I read reviews from others, but maybe because I have such a thick drill bit, I never experienced what others experienced yet. The bit never broke midway through, nor has the drill tip changed shape or whatever else I've seen. I'm nowhere near down protecting the building but I have already drilled out nearly 50, 5-inch deep holes with this drill bit and there's barely any sign of wear and tear. At the same time though, I have a bucket of water to cool down the drill bit to prevent the heat from changing the shape and I constant check to make sure I'm drilling straight in the same direction to prevent the drill bit from bending. From my honest opinion, these drill bits for the price that they're at, they're way too good to be given bad reviews and I'm genuinely believing the people that didn't have a good experience with these either didn't properly handle the drill bit OR really actually received a faulty bit, which does seem understandable if they are making these at this price point so you have to give them some slack.

Good SDS plus bit, a quad cutter would be better and faster but also more expensive. SDS bits are somewhat disposable so these work quite well.
