The Hikoki NR1890DCA is an 18V cordless nailer designed for professional construction and woodworking applications. This pneumatic-style nail gun accepts D34-90 nails ranging from 34 mm to 90 mm in length and is suitable for framing, ceiling construction, sheathing, and other heavy fastening tasks.

Weighing approximately 3.2 kg without the battery, the nailer features a depth adjustment for precise nail placement and a single-shot mode for controlled operation. Its ergonomic design includes a rubberized grip for comfortable handling during extended use, while the magnesium housing ensures durability with reduced overall weight. The tool comes in a HSC IV hard case for safe storage and transport. With a magazine capacity of up to 100 nails, this nailer delivers consistent driving power with minimal recoil. The contact safety mechanism prevents accidental firing, and the device includes a built-in air blower for cleaning work surfaces.
