SDS Plus 1-1/8" x 18" Rotary Hammer Drill Bit, Carbide Tipped for Brick, Stone, and Concrete … (1-1/8")

Good as advertised and arrived on time.

I bought this really large drill bit to drill through my brick and block wall to install outside water spigot. It drilled through the brick then the blocks behind the brick with ease. Be sure to put a little water in the hole your drilling to keep the bit cool. Heat destroys any type of drill bit. Overall this bit is a hoss and did a great job. User beware, it's not easy drilling in concrete. It will give you a great upper body workout.

Good

Went through my 14 inch rockwall. I was impressed

I used this bit to drill through about 15" of concrete and it worked pretty well for such a large hole. It did take about 10 minutes, partially due to my dewalt sds hammer drill eating a few of the small 2ah batteries in the first half, but after putting a larger 6ah battery on the tool it got the job done quickly and the tip of the bit still seems to be in fair condition. It has a nice spiral design that brought all of the cuttings out, just a little water every couple of minutes made a nice little slurry.
