Does Hitachi Make Metabo?

That’s all right! When Hitachi rebranded as Metabo, it is unavoidable that we’d inquire, “Does Hitachi still make framing nailers or other power tools?”

Metabo was a brand of the renowned power tools manufacturing company, the Metabowerke GmbH. Headquarter was in Nürtingen, Germany, and was founded in the 1920s. Later on 1st March 2016, Metabo was acquired by Hitachi Koki – a concern of Hitachi Group. However, just a year later in March 2017, Hitachi Group sold its sister concern Hitachi Koki to HK Holdings Co., Ltd., an entity of the investment firm KKR (Kohlberg Kravis Roberts) through a tendering process.

After that transition, Hitachi Power Tools has been renamed Metabo HPT on the eve of 17th October 2018. All new branded power tools ‘Metabo’ are currently manufactured in two factories in Nürtingen and Shanghai. And distributed its products worldwide through 23 companies and over 100 importers.

As professional woodworkers, we don’t find much of a difference in quality. Instead, it transforms into something more innovative and trendy than it was previously. So, we may infer that rebranding or switching to a new company could not jeopardize Hitachi’s original performance.

In fact, Metabo HPT is nothing more than a brand name for Hitachi. You’ll find the same devices with the same quality, warranty, and guarantee policy. You’ll notice that they both use the same batteries. Hitachi MultiVolt batteries and Metabo HPT MultiVolt systems, as well as Hitachi 18V batteries, are interchangeable.

As a result, we’ll see the same packaging and color scheme as the label, which leads us to assume that it’s just a name change.

Detailed Features Of Metabo HPT NR90AES1

Next Generation Design

Technology is Hitachi’s primary driving force, which makes Hitachi a world-renowned company and leads to the development of products with superior design and reliability. NR90AES1 framing nailer also featuring Hitachi’s next-generation “industrial design.” It comes with a revamped head guard that helps you to disassemble the unit faster and easier than before, saving valuable time during tool maintenance.

Extremely Durable And Lightweight

The Metabo HPT NR90AES1 itself is a little over seven pounds or precisely seven and a half pounds, which is extremely light, and a framer, no matter if he/she is a pro or a DIYer, will work with it all day long.

The NR90AES1 also allows you to work in tighter spaces, and the collar around the muzzle cuts into the wood just enough to get a decent toenail in while you’re hanging from the roof in awkward positions.

Not only is the gun light in weight, but it’s also rugged and can take the job site abuse. It can absorb socks if it suddenly drops from a full eight feet of height of your ladder. Metabo HPT nail gun made of flexible materials, aluminum, which gives it extreme toughness to protect it from damage. And, even if you drop it until it splits, it won’t kill the device entirely.

However, if the tool had a hook, it would be more convenient to hang it with a belt or trunk when operating at height.

Selective Actuation Switch

Changing the mode of actuation is nothing a big deal. But when you need to handle a project that demands frequent shifts of speed, a selective actuation switch comes in handy to increase productivity.

The Metabo HPT Tool knows it well and designs its NR90AES1 pneumatic framing nailer with a selective actuation switch, which allows you to change the actuation mode from sequential to bump by merely flipping a switch. It’s really easy to do. Yes, indeed!

Rubberized Grip

Metabo HPT framing nailer is an ergonomically designed tool that ensures the proper balance during nailing. Besides being ergonomic and lightweight, it also makes the handle sturdy and comfortable with a rubber grip that protects accidental slip during operation.

The tool-free depth adjustment mechanism of the Metabo HPT framing nailer allows you to adjust the depth just by setting the air compressor pressure.

The two-step nail loading system of Metabo HPT NR90AES1 makes fastener replenishments quick and easy. After inserting the nail strip from the back of the magazine, slide it forward through the magazine until it reaches the nail stopper. Then, pull the nail feeder to engage the nail strip correctly. That’s it. Its two-step nail loading process also helps you to reduce the downtime of work.

Freeman PFR2190 Vs Metabo HPT NR90AES1: A Comparison

Although both the Metabo HPT and the Freeman nailer are pneumatically driven and built to drive 21-degree plastic collated nails with lengths ranging from 2 to 3-1/2 inches, they have certain similarities and differences that render one superior to the other. Let’s take a look at them-

While the Metabo HPT is an excellent choice for framing and other woodworking activities, we found that it lacks some useful features when compared to the Freeman PFR2190 nail gun.

The 360-degree adjustable exhaust, no-mar tip, no-slip teeth, anti-dry fire system, an air filter, or anti-dust cap are all included in the Freeman nailer. Even though they aren’t the most important component, they are essential for a nailer’s comfortable operation.

However, Freeman made its body out of magnesium rather than aluminum to make it more durable for long-term use. And you’ll get all of the extra features we mentioned above without spending any more money, or even less than the Metabo HPT.

On the other hand, the Metabo NR90AES1 is lighter than the Freeman PFR2190, allowing you to drive nails all day without being fatigued. A flip switch for fast firing mode switching, an innovative head guard design for easy maintenance, an open nose for tool-free jam clearing, and a convenient rubber molded handle is also included. These features contribute significantly to the reduction of work time and effort required for framing.

Again, both nailers will help you obtain a long-lasting magazine, tool-free depth adjustment system, smooth toenailing, and other features necessary for a successful fastening, framing, or deck-building job.

Now, if you want something affordable but capable of performing all basic to advanced framing tasks, the Freeman PFR2190 is a good option. Otherwise, Metabo HPT NR90AES1 would be your cup of tea if you want something renowned and outstanding.

Is The Product Worth Your Money?

You can see from the above discussion that, while the Metabo HPT framing nailer has some minor drawbacks, it also has a slew of excellent features that make it a unique tool for both beginner and seasoned users. It also comes with a five-year warranty to protect your investment. As a result, once you have purchased it, it will undoubtedly be worth your money.
