My air ratchet was useless with the same airline fittings as in the second video I posted above ,it was very slow spinning until I changed to bigger fittings and a bigger airline .
High flow connections and hoses can make a big difference with air tools.
My air ratchet ,I turned into a drill by putting a chuck onto a half inch socket ,I was able to drill out broken exhaust manifold studs between the head and the strut tower on my car.
