Review on Top-performing Mayhew 31970 2 Inch Pneumatic Chisel: A Powerful Tool for Efficient Precision Work by Matt Welch

I bought an Ingersol air chisel, recommended 3" nozzle and recommended 2" nozzle. I am installing a lawn edging extension about 6 feet long. I used the 3" attachment to cut the line in the grass and the new 2" attachment to slide across the lawn surface to clear the path. THIS ONE! , (I'm a mechanic), removed the balls to see the bit hub through the holes. The bit sleeve is worn out in such a way that it CANNOT be removed. making my new tool useless. I have old beats for my lil wimpy, you old ones that are perfect. It sucks. What now? I have your soft nozzle in the new Ingersol cartridge, it disables the tool. let me know how to play it (added photos)
