If you're going to drill a lot of holes into concrete, do yourself a favor and buy a drill designed for SDS-Max bits. The difference is amazing. Before, we were using SDS-plus bits with powerful drills, but it took my mason on average 1 minute per hole. After switching to SAD-Max, he drilled similar holes in 15 seconds. We were amazed, and the guy has drilled many thousands of holes in his life.I had never head of the Sabre brand of drill bits, but it's the only brand I could find in the size that I needed. It performed beautifully, drilling hole after hole, as if it were into butter, and yielding as many as 70 holes per bit. vs. about 40-50 for the SDS-plus bit. I will be looking again for that brand in the future.

Drilled 8 holes in 8” poured foundation walls

worked perfect to put 3/4 pvc conduit through block foundation

Using a Hilty drill, I was able to drill a 1 1/4 inch hole through brick and a cinder block in 30 seconds or less. For those asking questions about running this bit using a hammer drill, you can't. The shank is at least 3/4 inch around and the "slots" would make it impossible to chuck it in a 1" drill. People who asked questions about how big the shank were greeted with "it's a MAX"... not the actual diameter of the shaft. I could not find any reviews or answered questions where someone actually gave an answer in inches. I didn't know what "MAX" meant until I went to a True Value Hardware to rent the Hilty.

Great value
