The Milwaukee M18 FUEL 21 degree framing nailer sets the new standard for cordless framing nailers. It has a nitrogen spring mechanism, POWERSTATE brushless motor, and REDLINK Intelligence, providing pneumatic performance and cordless convenience. The framing nailer can sink full round head nails into dense engineered lumber to tackle the most demanding framing applications. To increase productivity and efficiency, the framing gun fires 3 nails per second with zero ramp-up time, firing a nail as soon as the trigger is pulled. The cordless framing nailer uses only Milwaukee's REDLITHIUM batteries (not included) and sealed compressed nitrogen to drive each nail, eliminating the cost of gas cartridges and associated maintenance. The M18 FUEL 21 degree framing nailer delivers pneumatic performance and durability that professional carpenters and remodelers expect, without the hassle of a compressor and hose or gas cartridge.
