Took my time, used lube, slow speed and it went through 2x3 1/4 wall steel pipe quicker than expected. This replaced my Matco saw which I bought circa 1989. I hope this one lasts just as long.
I bought this hole saw specifically to cut some holes for some air vents but ended up using it on a few other projects as well. He did everything great and continued to work exactly as expected in every situation!
I bought this because it was about 2/3 the cost of other hole saws. I should have known better. It says "optimized for metal" when it should be "only for metal". You will break your hand if you try to use it on wood as the teeth are too aggressive. I ended up spinning back and burning through the wood after nearly breaking my wrist. Back and forth on my switch to a Dewalt hole saw.
