The Milwaukee 21-Degree 3-1/2" Plastic Collated M18 FUEL Cordless Framing Nailer Kit (2744-21) sets the new standard for cordless framing nailers. By leveraging a nitrogen spring mechanism, POWERSTATE brushless motor, and REDLINK Intelligence, this nailer provides you with pneumatic performance and the convenience and freedom of cordless power. Delivering the power to sink full round head nails into dense engineered lumbers, this framing nailer allows you to tackle even the most demanding framing applications. To keep you productive and efficient throughout the day, the framing gun fires 3 nails per second with zero ramp-up time, meaning a nail is fired as soon as you pull the trigger. Additionally, the cordless framing nailer operates using only REDLITHIUM Batteries (not included) and sealed compressed nitrogen to drive each nail, completely eliminating the cost of gas cartridges and maintenance associated with competitors’ nailers.
