Driving fasteners into concrete or steel can be painfully slow and difficult, but Toolmongers during WWII needed a fast way to attach a steel-plate patch to the steel hull of a damaged ship. So, Yankee ingenuity produced powder-actuated tools. A chemical propellant — like gunpowder — explodes inside the tool and drives the fastener, with action similar to a firearm.
For a guy with a home shop, who infrequently needs to attach things directly to steel or concrete, a single-shot model like this one should fit the bill nicely. If you’ve got a lot of fasteners to drive, you might want a semi-automatic model.
Street pricing for the Ramset Single Shot RS22 is about $75.
