The Milwaukee 1-3/4” Coil Roofing Nailer features an ultra-lightweight magnesium housing to minimize fatigue. Its compact size offers greater maneuverability. The magazine holds 120 galvanized wire collated nails from 3/4 in. to 1-3/4 in. length and .120 in. diameter. A magnet holds the nail in place making loading fast and efficient. The thick rubber guards minimize housing damage. The tool-free depth of drive protects from overdriving nails. The self-cleaning air filter extends life by preventing dirt and debris from entering the tool. The adjustable air deflector with muffler directs exhaust away from the work area and holds down the noise. The textured selectable trigger lets you move from sequential or contact actuation by simply turning a knob. A removable shingle guide assists in quick shingle alignment.
