I needed to get a hole in a brick wall for a new gas line. This bit really did the job. Made short work of a big job.

I was a bit hesitant to buy Milwaukee brand but since it was the only brand available at the store that day that had the diameter size I needed. I used this drill bit in recently poured concrete post, to install a retrofit bolt anchor. Worked well and made easy work of drilling on the concrete.
