Your cart is empty.Bosch round hammer drill bits deliver 4x life vs. Standard masonry bits. These bits feature asymmetric diamond-ground carbide tip for precise starts and less bit walking. The bit heads were built to be robust with the best quality to resist the toughest jobs to last longer than standard masonry bits. They have milled u-flutes with deep-cut Spirals for fast drilling in Block, masonry, and concrete. The grip shank provides aggressive gripping power.

Use this to drill through a masonry block wall with stucco on the outside and drywall on the inside. Needed to run a wire and this drill bit along with a hammer drill made the job go smoothly.

This got me through a stucco wall to aid in bringing wire to equipment outside.The drill bit was almost out of the big box it Amazon packaged it in.🫤

Took some force to get through stucco, but ultimately got the job done.

I needed a long bit because there was a railing in the way when I was hanging some shutters. This bit was just the right length and drilled into the brick easily.

I used this for a few holes in a cinderblock wall. This was able to go through both sides without issue. Took a little more work on one part of the wall than I expected but overall worked well.

Versatile and long drill bit. Seems sturdy enough and hasn't broken while drilling some holes into an ashfalt driveway. Probably wouldn't recommend for heavy duty jobs, but great for light to med/light drilling needs.
