The Metabo HPT 30-Degree 3-1/2" Paper Collated 18V Cordless Framing Nailer Kit (NR1890DCSM) completely raises the bar for cordless framing nailers. It is designed so you no longer need the dirty hoses, loud compressors or expensive gas cartridges. It's equipped with Metabo HPT's unique Air Spring Drive System that delivers similar performance as a pneumatic nalier, but offers total cordless freedom. It uses sealed compressed air to drive each nail, which results in zero ramp up time, up to 2 nails driven per second, recoil that feels like a pneumatic nailer and best of all, there is no refilling of the air tank required. This cordless nailer is ideal for all construction framing applications but is particularly useful for punch-out work on a jobsite for quick in-and-out operation with minimal hassle and professional results.
