Senco FN55AX 18 Gauge Fusion Nailer


Product Description

Senco's Fusion technology gives you the power of a fuel or air tool without the inconvenience of compressors and fuel cells. A permanently sealed canister stores compressed Nitrogen gas as a source of energy. When the trigger is pulled, energy is released, the motor turns the lifter which resets the piston. Nails are fired with no trigger delay. The entire process is powered by an 18V Lithium-Ion battery which can deliver up to 600 drives per charge: no fuel cells required! In addition to this revolutionary technology, Fusion Nailers also feature benefits like an adjustable firing mode (Bump Style, Sequential, or Off), precise depth of drive adjustment, and a self-correction capability.

  • Cordless Finish Nailer drives like air and fuel powered tools without compressors or replacement cells
  • Compressed Nitrogen gas provides energy for each shot with no trigger-delay
  • Nitrogen gas canister is calibrated and permanently set at the factory: no refueling required!
  • 18 volt Lithium-Ion battery provides up to 600 shots per charge
  • Lithium-Ion battery reaches 80% power in only 15 minutes and charges even when "hot"
  • Multiple firing settings: bump, sequential or off
  • Thumbwheel allows quick and accurate depth adjustment for countersink or flush drive
  • Built-in indicator provides an instant view of depth setting
  • Self-Correction mechanism automatically resets after power loss or time-outs
  • If tool is left on "Bump Fire mode", Safety Time-Out mechanism shuts off tool to prevent accidental discharges
  • Built-in work light illuminates dark corners and spaces for improved accuracy
  • LED fuel-gauge clearly displays available power to avoid sudden power-losses
  • Belt hook is reversible and adjustable for left or right handed users and a variety of tool belts
  • Capable of firing 5/8" to 2-1/8" 18 gauge brad nails
