It’s perfect for teaming weep holes to the exact diameter to receive 1” ID PVC

This was eating through concrete like butter but hit brick and came back to normal pace… then the shank bent. First use too. I don’t know if I can return it.

It worked well for me. It fits the ordinary drill, which is very nice.

It doesn't go through concrete like a knife through butter, but it does do a decent job. The other things it is supposed to be used on haven't come up yet, but we are assuming they, too, will yield to the diamonds. Glad to have it around

Besides being nice looking hole saw, it performs just as nice. I used it to make a hole for a metal stair railing. With a cordless drill it cut beautifully without groaning and moaning. Definitely worth the price. Oh , and it hardly showed sign of wear even though it went through 5,000 psi concrete.
