I'm sorry to hear the chisel didn't work very well. Did it stay sharp, or did it go dull? I wonder if the chisel softened up when you sharpened it. I like to dunk chisels in water right after heating them up on a grinder. Helps keep them from softening up.
I'm not sure what the brand was of the air chisel I used. I can tell you it was fairly large and heavy-duty feeling. I used it a bunch when I worked in a wrecking yard.
I removed my manual transmission crossmember using a drill and it took me about 6 hours. About three months later I removed some rivets for the first time using the air chisel, and I remember being totally amazed at how easy it was.
I'm sorry if I steered you in the wrong direction.
