Review on Astro Pneumatic Tool PRN12 Mandrels by Ronald Bleimeyer

So it's compact and 'should' make it easy to install rivet nuts in tight spaces. to avoid damage to the tool, but nowhere in the instructions is the recommended pressure specified. The included air regulator is part of the industrial air fitting, however I only use automotive air fittings so I have to purchase a separate in-line regulator if I know what pressure to set. I ordered a pistol because I can't fit a hand wrench where I need to place nuts. I'm about to install a seat and seat belt on a 1986 International trailer. I installed it today to attach my rivet nuts. Even with no airflow, it doesn't have enough force to crimp a 1/2" steel rivet at 120psi.
