BOSCH HC2062 3/8 in. x 6 in. x 8 in. Bulldog SDS-Plus Rotary Hammer Bit

Drills through concrete with ease. Bought this for a Bosch hammer drill. Bit does not run and cuts with accuracy. Great quality from a German made bit. I'm sold on Bosch bits and own quite a bit of them. Highly recommended.

Works

I needed to drill thru a concrete ceiling for some concrete screws. This bit on my rotary hammer drill cut thru the concrete easily. It went thru the concrete like cutting thru a bar of butter. The hole was clean and not expanding beyond the diameter of the bit as much when using a masonry bit on a regular drill.

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.

The bit on the left is the (1/4 Inch x 12 Inch SDS Plus) and the bit on the right is the (BOSCH HC2084 1/2 in. x 10 in. x 12). The size comparison is significant. I highly recommend these bits.

This bit will not get lots of use here. Need to drill through some outside concrete walls for security camera cable. The previous bit simply wasn't long enough.This bit fits my DeWALT 7 Amp corded hammer drill just fine, as do other SDS bits I've tried.I will not be drilling more than a few holes, so I won't have long-term results to report. But the price here on Amazon can't be beat. Less than 1/3 of the price at big-box stores as of this writing for the exact same bit.Update October 2024: Turns out I got a great price here, but the current price, while it's since gone up, is still very good. And when I finally used the bit, it went through concrete and cinder block very well indeed, and there's clearly lots more life left on the bit.

I recently purchased the Bosch HC2083 1/2 in. x 6 in. x 8 in. Bulldog SDS-Plus Rotary Hammer Bit and was blown away by its performance. I needed to drill through a concrete foundation for a new plumbing line, and this bit made the job a breeze.The bit is incredibly durable and powerful. It went through the concrete like butter, without any chipping or breaking. The SDS-Plus shank ensures a secure fit in my rotary hammer drill, providing maximum power transfer.If you're looking for a reliable and high-quality rotary hammer bit, I highly recommend the Bosch HC2083. It's a fantastic investment for any DIYer or professional contractor.
