Query: That's forty bucks I wish I had back

I was moderately satisfied when I first got these - kind of cheaply packaged, but I managed to modify the case so it worked, so I figured I had a set of good, super-hard, super-sharp bits for whenever I needed them.Well, I don't know what kind of steel a garden hoe is made out of, but it's more that these things can handle. I was pushing hard, changing the angle, tryng slower, trying faster, but all these things did was mostly squeal. At that point I was about convinced that I must have some kind of titanium hoe on my hands! Out of curiosity, I then put in one of my old steel bits (just ordinary hss bits - craftsman or something)and the metal started curling up the way it's supposed to. I had a hole in no time.There ought to be a law against making the claims made about these bits when they perform as they do.On the bright side, I won't have to worry about losing them...
