The Milwaukee 2458-21 M12 Cordless Palm Nailer is one of those types of tools that you probably won’t use every day, but it could prove to be a real asset when the occasion arises. We got a glimpse of this nailer at the 2010 Milwaukee Media Event where we were able to try out a few pre-production models – and they did prove very promising. We were slightly surprised that they were able to drive 16d common nails flush into 2×4 studs all day long. Finally a cordless, hand-held nailer that really drove nails. Up to now, the few battery powered nailers that we have seen, also known as auto hammers, have been more like gadgets than real working gear. The idea of being able to leave the air compressor, air hose, drop cords and nailers in the work trailer is rather compelling. Given its fairly compact size, you can drive nails in those difficult tight spots where you normally might not be able to fit a full size nailer or swing a hammer. To make it even better there is a LED work light built in that should make it easier to see what you are doing in a dim or dark work area.
