When we posted the results of our best framing nailers review, we got some feedback that reflected the same thoughts we had—why didn’t the Metabo HPT (formerly Hitachi) do better? The NR83A5 is one of the best framing nailers out there, but it came in at number 10 overall after our battery of tests. Still, we wondered how the Metabo HPT NR90AES1 framing nailer would fare in the same set of tests. It's cheaper, lighter, and supports 3-1/2" nails instead of 3-1/4". It should have more power.
metal back cover
We love seeing metal backs on framing nailers. It helps with durability when those tools are bumping around. I know none of you hammer studs with it, do you? After all, that would be dangerous.
metal magazine
The Metabo HPT's magazine lets you store two nails like all the air nailers we tested. With the post-pin insertion and metal construction, the overall slide action of the magazine is excellent.
Single stage mode change
Easily change modes with the Metabo HPT NR90AES1 Framing Nailer. A simple switch sits above the trigger. You don't have to push it in from either side, and you don't even have to think about trigger changes.
depth adjustment
The depth adjustment is located under the right driver assembly. It's a somewhat unusual location, but it's easily accessible and fairly easy to adjust.
missing features
- dry fire lock
- hook up
- adjustable exhaust
The lack of a dry fire lockout and hanging rafter hooks is especially disappointing. It was the only one of the 14 nailers in our comparison that didn't have a hook. Even when Metabo HPT rebranded the Hitachi models, it didn't make any changes. It's not the only one lacking a dry fire lock, though.
At 7.28 pounds, the Metabo HPT NR90AES1 Framing Nailer is the lightest nailer we tested. That's a big deal for professionals who spend their days framing shots. Ergonomically no complaints, with excellent balance and a comfortable handle design.
If there's any complaint, it's the head width. Nice length and height, but the wide head can sometimes get in the way if you're trying to nail corner areas.
shooting intensity
3-1/2″ nailers are supposed to be stronger than 3-1/4″ models, so it’s no surprise that the Metabo HPT NR90AES1 outperforms the NR83A5 here. With glued and stacked OSB as our medium, the NR90 was able to consistently deliver firepower into the material, with room in the depth adjustment to make it deeper. If you're looking for a nailer strong enough to handle denser materials, this is one you can rely on.
cringe
Despite its strength, the Metabo HPT controls the recoil of this framing nailer very well. There's some you'll have to deal with, but you can hand the NR90 to an apprentice without worrying about him spending half a day hammering his proud nails with control issues.
toenails
At first glance, this Metabo HPT NR90AES1 Framing Nailer appears to have a design problem with the tip. The side barbs are recessed so far into the top and bottom barbs that they appear ineffective. What actually happens is that they protrude slightly to the side. You have to grip at a steeper angle than some nailers, but they grip really well and arguably give you more consistent toenails. They also grip the studs well when you have to turn the nailer around and use the top barbs.
The bottom line here is that you can nail your toenails without the prongs slipping, and the recoil is low enough that you don't need to worry about the first nail popping the stud out.
visibility
While this pointy design can take some tweaking to your toenails, it's great for letting you see where your nails are. Once you see where the nail sinks relative to the nose (it's slightly higher than the center), you can confidently place the nail exactly.
air efficiency
The NR90 drives a 3-1/4" nail flush in untreated pine with just 85 PSI. Some framers are more efficient and can be done at 80 PSI. Others need more. If you're trying to use a small compressor, this nailer has moderate efficiency. It shouldn't slow you down too much from what you're already using.
You can get the Metabo HPT NR90AES1 for $169, which is a great deal. The only $140 Estwing in our shootout was cheaper, and it doesn't have the same reputation as the Metabo HPT and Hitachi nailers.
While the feature set is missing several key components, the nailer's performance more than makes up for them. Once we go through our magic value generator (we actually have a rather complicated equation to define it), it turns out to be one of the best values, scoring 4.75 out of 5.
the bottom line
If you need a nailer with great ergonomics and actuating power without a ton of bells and whistles or the price tag that comes with them, you're unlikely to find a better choice than the Metabo HPT NR90AES1.
