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.

Went through my 14 inch rockwall. I was impressed

Good

I bought this to install our Starlink cable through our basement entrance. It cut through our concrete wall like a sharp knife through butter.

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.
