BOSCH HC2083 1/2 in. x 6 in. x 8 in. Bulldog SDS-Plus Rotary Hammer Bit

With correct impact driver this bit cuts through concrete like it was a soft material. Quick to insert and remove in driver. Quality concrete drill 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.

long-time user. great aggregate drill

Good product. Fits in hammer drill nicely. Works well. Don't know durability yet as I only drilled a few holes but Bosch is usually a quality brand. Cheaper than in stores

Having never drilled through a foundation wall before, I wasn't sure whether my drill would be up to the task or that this bit would be sufficient. It's a 100 year old home and the wall was about 16" thick with stone on the exterior. I chose a mortar joint as a starting point. It took quite a while and a number of pauses to let the drill cool between sessions. However this bit was up to the task and I steadily made progress. There was no binding and fine powder was drawn evenly by the flutes to my opening. The result was a nice clean 1" hole that snugly accepted a section of 1" conduit that I only had to tap lightly at the end with a mallet. The drill bit looks no worse for wear and will be ready should I ever need to do this again.

Awesome bit. Has very good quality for the money. Has held up great for the 2 months I've had it. I've drilled about 8 holes with no problem. Drills most brick like butter so far. Fits great extact size built very sturdy.

Purchases to install frost free hose bib as there are none anywhere near that side of my house. At grade is the poured concrete basement wall- about 10” thick. I selected the 1” drill to make sure I had plenty of space for pipe. I would say it took no more than a minute or two of actual drilling with a couple stops in between. Drill bit performed perfectly and after wiping down can’t even tell it was used really. Thinking about picking up 3/4” size too just to have for next project.

I use these type bits a fair amount and if Im doing just a few holes of an odd size, I'll go get a cheap import bit, BUT if I have a bunch of holes to drill, I always use Bosch bits. I drilled over 100 holes 6" deep with this bit and its still going strong. The holes were drilled in cured concrete, not green concrete, so the bit did have to work and it shows very little wear and that is even after hitting some rebar a few times. I tagged some rebar hard enough to stall the drill and figured I chipped the carbide end...reversed it out and the carbide was fine. Very well made bits.

A great product, at a great price. I’m very happy with this purchase.

Really solid rock bit. I've done 40 or 50 holes in granite and some in limestone, basalt, and gniess. Still going strong. Highly recommended. Beats the pants of the hardware store bits that drop the carbide after 6 holes... Be sure to grease the sds drive and go lightly, you don't want to force the bit against the stone. It needs to be able to bounce a little to work efficiently.

Muy buena broca y estuvo en oferta en 333, bosch es líder en calidad de este tipo de brocas

I bought this bit for $34.20 on sale and I'm glad I did because the price jumped up to $50.39 the next day ... Yikes! I needed an extra long bit to drill through some brick to run a wire for a security camera. ⅜" was the perfect size and 24" inches was the perfect length. I've used shorter Bosch concrete bits in the past and found them to be good quality. This extra long 24" bit is no different. The build quality is excellent and it drills through cinder block and brick like butter. It fits my SDS hammer drill and even after drilling half a dozen holes still looks like brand new and sharp. I'm going to use this drill bit next for some rebar for a retaining wall. I would highly recommend this Bosch SDS drill bit and any other Bosch SDS concrete drill bit. I've had a good experience with all the Bosch SDS bits I've used so far and will stick with them as long as they stay affordable.

Did the job, drilled about 25 holes into my pool deck for a new cover. No wear on the bit at all.
