Makita’s 2-1/2-inch High Pressure Siding Coil Nailer, model AN635H, features high pressure technology for more consistent flush nailing with less weight and a more compact size. The AN635H can operate at high pressure (170-320 PSI), and with its high pressure capacity and superior power-to-weight ratio is up to 30% more compact than a conventional nailer. The AN635H also weighs less – only 4.9 lbs. – yet holds up to 400 nails in sizes ranging from 1-1/4-inches to 2-1/2-inches. With increased pressure for driving each nail, the AN635H delivers more consistent flush nailing. “Tool-less” depth adjustments have been engineered to provide the option of precise flush or countersink nailing, and includes both a single sequential actuation trigger or a contact actuation trigger allowing one to control their nailing operations. The AN635H has an easy-load nail canister and a see-through window. The canister base adjusts easily for various nail sizes, delivering faster, more efficient loading for increased productivity. For user comfort, there are large rubberized grips, a tool hook to keep the nailer close by while not in use, and a side exhaust port to direct exhaust air away from the user. Additionally, there's a built-in air duster that provides convenient air flow to clear your work surface.
