Metabo HPT, Hitachi 's current brand, is bringing a breakthrough in the field of cordless framing nailers. The role of pneumatic features in woodworking, furniture making, and other construction works is known to skilled carpenters. Yet they don't like all those messy cables and noisy compressors to hang on. Keep this in mind Metabo HPT NR1890DR comes with a unique spring drive system that gives you a taste of compressed air without getting into contact with hoses.
Hitachi cordless framing nailer offers two identical models, Hitachi NR1890DR and Hitachi NR1890DC. The difference between two is one can drive the round head plastic collated nails and other clipped head nails.
Today, we will talk about the Metabo HPT NR1890DR 18V Cordless Framing Nailer, which built to provide you max holding power and powerful drive. Let's dive in.

Features of Metabo HPT NR1890DR
Unique Air Spring Drive System
If you ask what makes the Metabo power tools inimitable from other battery-powered nail guns on the market, the answer is its air spring drive system.
Though it primarily operates by battery power, you will get the performance of compressed air in it. Let’s explore how it works? More specifically, how the air spring system work?
What is the Working procedure of air spring drive system?
Metabo's unique Air Spring Drive System uses an airtight compressed air cylinder to shoot nails. Practically, the brushless motor uses the power of the battery to roll the spring. The piston attached to this spring then pushed through the chamber and pressed the air into it, which stored kinetic energy there. When you press the trigger to shoot a nail, all the compressed air is quitted, push down the piston forcibly, and hit on the nail in the lumber. All these happen within a fraction of second.
However, this system is very distinct from a car engine that needs fuel (gas or petroleum) and combustion power to remain at velocity to drive forward.
You might think it's a lengthy method, but it's not. In reality, the brushless motor starts working even before the trigger pulled. It implies that when you fire the nailer, the fastener pushed with zero lag at once. It's always prepared to hit the next nail. The method is fast enough to drive 2/3 nails per second, and its recoil feels like an excellent pneumatic nailer.
Air spring drive system, therefore, will give you the following advantages -
- Zero ramp-up time and faster response time between drives
- No burning noise and no gas fumes
- Consistent performance at low temperatures or high altitudes
- Less maintenance due to no need for regular cleaning of the combustion chamber
We have already said that a brushless motor operates the Metabo power tools' spring drive system. Similar to the Dewalt framing nailer, the brushless motor of NR1890DR is also design to deliver longer run-time per charge, less maintenance, and rise durability. The frictionless brushless motor also ensures added life and superior performance that helps you to sink up to 3½ inch nails effortless through 5/4 decking boards or 4x4 engineered lumber all day long.
A powerful 18-volt 3.0Ah Lithium-Ion battery used to supply power to the Metabo HPT NR1890DR. That means you could drive up to 400 nails in a single charge with it. Not only will you get enough driving power from it, but it will also give you compact size, and compatibility to use this to all of your other 18v slide-type Li-Ion Hitachi or Metabo cordless tools.
If you think this number is not enough to speed up your project and drive more nails per charge, there are also options. It allows you to upgrade the battery power up to 5.0Ah to 6.0Ah. With a 6.0Ah battery, you can flush 780 nails per charge. Happy! Ha!
Please look at the ampere vs. the number of nails per charge graph below for better understanding.
Low Operating Cost
If you have a Metabo Cordless Framing Nailer, you could save 25% of your operating costs as you no longer need to buy any gas cartridge or air compressor. Moreover, you can drive 25 percent more nails compared to a fuel cell-powered nailer with it. Let's see the graph below to get more indulgent.
- Without the cost of nails.
- The numbers of the total cost were relative values when the initial cost of competitor's gas framing nailer indexed at 100.
- Electricity cost may vary depending on the state you stayed.
The new Hitachi cordless framing nailer came in the market in 2018 and equipped with a control panel situated right at the base of the handle. You can control particular settings with this panel by pressing buttons.
Depth of Drive
Adjustment of drive depth is a crucial setting for each nailer. Metabo nail gun addresses it rightly and designs a quick change wheel/dial to align the depth-of-drive, which helps you get precision nailing. Based on your working surface density and variety, now you can set your desired drive depth without using any tools.
We love to mention that Metabo HPT comes with a pivoting rafter hook. Well, you will enjoy it. It's large enough to hang the tool from a 4x beam, and it's easy to rotate in or out of place as required.
Non-slip rubberized soft grip reminds us of the mastery in ergonomics of Hitachi power tools. Yes! Because of its ergonomically designed handle, you could enjoy driving nails all day with comfort. It also comes with a side lock trigger switch located on the handle, which prevents accidental firing when the tool not in use or you carry it from one place to another.
The tool with battery is of 10.8-pound weight, which seems a bit heavy but practically well balanced for easy maneuverability. Dry fire lockout system prevents nailer from firing when fasteners are low for added safety.
Power Saving Mode
Are you going to lunch break without disengaging the battery from your Metabo cordless tools? There's nothing to worry about! The Metabo HPT NR1890DR will automatically go to sleep mode after 30 minutes of inactivity. This function enables you to save battery power from unnecessarily drain-out and also ensure safety, as no one can accidentally drive nails at that interval.
If you want the tranquility of mind, at the same time, not want to annoy your neighbors, then you come in the right place. Metabo Hitachi cordless nailer concept so that you can achieve the same efficiency as a pneumatic nailer without any combustion or compression noise, drag hoses, or even the smell of gas fumes. Not only is it quiet enough, but it will also provide you consistent efficiency even at low temperatures and high altitudes.
Pros of Metabo HPT NR1890DR
Cons of NR1890DR with Solution
We’ve not found any significant drawbacks of this super cordless nailer that abide you from buying this. One thing I can mention that it has no tool-free jam clearing option, however, you will face very infrequent jam issues in this, and it comes in an as usual tools bag instead of a hard plastic case, which makes transportation a bit unsafe.
If you compare it with Paslode 905600 cordless framing nailer, you may also complain about its weight (10.8 pounds). However, if you palm it, you can feel how well balanced it is and forget about it overweight.
Frequently Asked Question (FAQ)
Q1. Is there any quick charger in the package? If so, how long does it take to fully charged?
If you purchase it from Amazon, you find two packages. One contains battery and charger, and another is a bare tool (no battery included). So, if you choose the kit with battery and other accessories, you will find a fast charger (UC18YSL3) along with it too. The rapid charger will take only 45 min to full charge.
Q2. Is this device compatible with all branded nails or only accept Hitachi nails?
You can drive any brand nails with this device without any issue. However, if you stick with Hitachi nails, it is better for your nail gun life.
Q3. Am I sink a nail with this device in any hard or engineered wood without bulging or sagging?
Lack of power and runtime is a common phenomenon for the cordless nailers. However, the new Hitachi cordless nailer uniquely designed that capable of creating enough energy to actuate 3-1/2 inch nails to any hard lumber or LVL easily. In fact, the brushless motor and spring drive mechanism are working behind this compelling one.
The new Metabo HPT NR1890DR 18V Cordless Framing Nailer is a unique blend of Japanese qualities. It utilizes sealed compressed air to fire each nail, which results in zero ramp-up time, short recoil that works like a pneumatic nailer and, the best part is that no replenishing of the air tank needed.
The powerful battery and compressed air mechanism make this cordless nailer suitable for all construction-framing applications. It is particularly helpful for work-outs on the job site for fast in-and-out-of-work with minimal difficulty and professional outcomes.
