Hitachi Power Tools Cuts the Cord Hose with its new series of cordless framing nailers. Get more done with less and experience total fastening freedom from Hitachi by losing the dirty hose, the noisy compressor and expensive gas cartridges. These cordless framing nailers utilize Hitachi’s unique Air Spring Drive System that uses sealed compressed air to drive each nail.
How Does A Cordless Framing Nailer Work?
The piston rests part way down the cylinder when the tool is powered off but when powered on, the brushless motor drives the piston to the top position, compressing the sealed air. Once the trigger is depressed, the piston shoots down and drives the nail. This unique system results in zero ramp up time, up to 2 nails per second in driving speed and recoil that feels like a pneumatic nailer. Best of all, there is no need to ever refill the tank. However, if the nailer should require maintenance such as a Driver or O-ring replacement, these nailers can be easily serviced by any Hitachi Authorized Service Center (ASC). Once work is complete, the ASC uses a Hitachi issued tool specific re-fill regulator gauge that automatically re-fills the air tank to the nailers specific requirements and then nailer is ready to go.
Hitachi NR1890DR and NR1890DC
The NR1890DR 18V Cordless Plastic Strip Nailer accepts 2” up to 3-1/2” 21° plastic collated strip fasteners. At 10.8 lbs., with the compact 3.0Ah battery, this cordless framing nailer is well-balanced for easy maneuverability.
The NR1890DC 18V Cordless Paper Tape Nailer accepts 2” up to 3-1/2” 30°+/- paper tape strip fasteners (either clipped head or offset round head). At only 10.6 lbs., with the compact 3.0Ah battery, this cordless framing nailer is well-balanced for less user fatigue.
Control Panel
The on-tool control panel located at the base of the handle centralizes the power button, battery charge indicator and selective actuation. To activate the tool, the power button must be depressed for more than 1 second until the green light appears. After 30 minutes of inactivity, the nailer powers off for added safety and to conserve battery power. The battery charge indicator button can be depressed to check the available power in the battery pack, for less downtime. The selective actuation button lets the user quickly select between sequential mode or bump fire mode.
Battery Life
Both nailers are capable of driving up to 400 nails per charge using the included compact 3.0Ah battery.
Other Features We Love
Both models are equipped with a convenient tool-less depth-of-drive dial that can be easily adjusted to adapt to woods of varying density. The pivoting rafter hooks adds convenience for when the tool is not being used. Its larger size is designed to fit over 4-by material or triple stack 2-by material. The ergonomically formed, non-slip rubber grip handles are designed for comfort during extended use and a safety lockout feature is employed as an additional safety measure. In contact mode, when the trigger is pulled, the nailer must be depressed against the intended material within 2 seconds or the trigger will lock. In sequential mode the trigger must be pulled within 2 seconds of depressing the work contact or lock-out will occur. To unlock, the trigger is simply released and then pulled again to resume operation.
