The best gets even better. The NR83A3 has the legendary durability and reliability you have come to expect from Hitachi, but now with faster driving speed and improved response. With the power to drive 2" - 3-1/4" nails into even the toughest materials and tool-less depth of drive for convenient flexibility, there is no job this tool can't handle. The rubber grip adds comfort and control while the selective actuation switch makes going from sequential to "bump-fire" simple, without the need to replace or modify the trigger. The hardened claw tip and two piece steel magazine add durability to keep the tool out of the shop and on the jobsite, right where it belongs.
