Review on Spyder Rapid Eject 3.25-Inch 600036 by Joe Fulce

I have bruises from the recoil of this hole saw. When it snags, it spins the drill so hard that the drill spins and hits the closest object, like my forearm. Also, the holes it cuts in 2x4 are rough and ugly. Definitely a fine work tool. OTOH, it pits and it's a lot easier to clean the core than other pits I've used. And it seems just as sharp after a few holes. It just gets stuck too often.
