This coil roofing nailer is one of seven new heavy-duty air-powered nailers from the venerable Milwaukee, and the whole series is another testament to the red label’s unflagging quality.
At the top of our list is how incredibly light Milwaukee’s nailers are, even fully loaded, and their compact size makes them a cinch to tote and use, especially in awkward positions. But a close second is the clever inclusion of a magnet that holds onto the nails as you’re loading and significantly speeds up the process, reducing fumbling and dropped fasteners. Another big tip of the hat to Milwaukee for incorporating both sequential and bump firing modes, accessible just by turning a knob, so when speed is a need, you’re ready to go, but precision is at your fingertips too. We like the quality built into this tool, from the magnesium housing to the rugged rubber bumper guard that protects your investment should the tool take a fall. The hassle-free replaceable nosepiece has hard-wearing carbide inserts, and there’s even a self-cleaning air filter in the tool handle, keeping dust and dirt out of the tool’s workings – and that means longer tool life. The shingle guide is a handy touch, and we like that it’s easily removed when it’s not needed.
In hand, this nailer feels great: light, comfortable, agile, and beautifully balanced. Loading fasteners is a breeze, depth adjustment is on-the-mark reliable, tool-free, fast and easy, and we couldn’t get the thing to jam. Roofers and contractors will love this nailer. --Kris Jensen-Van Heste
