I used this drill with my new 18V Rotary Hammer drill to drill holes for rebar fence posts around my asparagus patch. The desert rabbits gobble anything green. I drilled into decorative wall blocks. I went 3 inches deep in under 4 seconds each hole and this drill showed no signs of use at all. They are less costly if you buy a set.

I had to drill 16 anchor bolt holes into very hard aggregate concrete. My regular 1/2" drill was making no headway. I purchased this drill bit and a rotary hammer and all the holes were done in less than 5 minutes. This bit really works well.

As a commercial carpenter I have purchased dozens of these drill bits of all different sizes, they perform well with continuous use, this is a quality product, I still have many that I purchased years ago.

Drilled holes in concrete without a problem. Did not drill enough to evaluate how long it would last but saw no degradation while using it. Positive lockup in the Bosch drill.
