This Hitachi nailer offers a fastener diameter range of .113-.148, a fastener length capacity of 2-3-1/2 and holds up to 64 nails. Boasting an operating pressure of 70-120psi and a 21-degree magazine angle, this NR90AE(S1) nailer can tackle a wide range of jobs, big or small. The NR90AE(S1) features a newly redesigned head guard that allows for a faster and easier disassembly process, saving valuable time during tool maintenance. The NR90AE(S1) weighs only 7.5 pounds, reducing user fatigue, while still providing the power of bulkier, heavier nailers. This Hitachi pneumatic framing nailer is designed with a selective actuation that switch adds the convenience of being able to quickly change between bump or sequential fire and the tool-less depth of drive that eliminates the need to adjust the pressure at the compressor. The simple two-step loading feature makes fastener replenishment quick and easy, reducing downtime.
