The trick with them hole saws is keeping them cool, very low rpm, and low duty cycle, like cut for 20 seconds, rest for 10. When they get hot the teeth just melt off.

I will place bets that you will get threw at least 2 full cages before replacing a hole saw. they work really good with that notcher.
