Rated 5.0 out of 5.0 by Brian 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.

Rated 5.0 out of 5.0 by Cableguy works great!
I'm a cable technician in Pa and purchased this bit as a substitute for my company issued one for when I'm in tight places and have to drill. This bit works like a dream. Keep up the good work!

Rated 5.0 out of 5.0 by Djinn Anchored Gun Safe
I purchased this bit for anchor my gun safe. It literally took about a minute to drill all 4 holes with my Makita Hammer SDS Plus Hammer drill. I have full trust in Bosch SDS Plus bits and that's what I've only buy as a companion to my Makita. Highly recommended.

Rated 5.0 out of 5.0 by Csatt Bosch makes a good product
Needed 11 holes through 8" of concrete. Took less than 10 minutes, closer to 5 to accomplish this task. Drill worked as expected. Have 8 Bosch drill bits all have performed well.

Rated 4.0 out of 5.0 by TiZef Good performance to drill trough concrete block walls.
If accuracy is not important this bit can be used without pilot hole no problem. I made 15 holes through a concrete block wall and the performance was unchanged from the first to the last. Apply a regular pressure and let the bit work for you. Few backup are necessary as the extraction of the dust is good. I recommend drilling a pilot hole with a hammer drill bit of less than 1/2 the diameter of the long one. It guides the long bit for better accuracy on where it ends up on the other side of the wall.

Rated 5.0 out of 5.0 by Blaze ate through the concrete like it was butter, and cleaned the hole as I drilled without having to pull the bit out all the time. Love it
awesome to use, fast drilling, clean hole with catching when hitting a bigger rock. self cleaning as I drilled. I punched twenty holes that were five inches deep in twenty minutes. This is the bit to drill holes with.
