I made a few tools for it last night out of air chisel bits, made a fixture plate for it, and bolted it to the wall. I messed around with it and textured some 1/4" thick mild steel with it cold and no heat, which was the first time I ever used one. It is easier than I thought, and very precise. I like how the depth of the bit's penetration can be controlled with the check nut. One great thing about it is that I can use it a 2am with out my neighbors knowing.
