Hitachi N3804AB3 Review Summary:

Many people avoid pneumatic tools because they think it’s too complicated to use them. However, that’s not the case at all, especially with modern staplers. Thanks to the modern technology and innovative designs, a vast majority of staple guns that are available on the market are simple and easy to use, even if you don’t have any previous experience.

One of the main problems with today’s market is finding a suitable pneumatic stapler that meets your requirements. In fact, a vast majority of them probably do meet your needs, but many of them are simply not worth investing in. There are a few reasons for that – poor quality, lack of important features, and most importantly – inadequate price. We are here to offer advice, guidelines, and a couple of models that we consider worthy. If you’re interested in purchasing a quality DIY tool, keep reading, and you might find this particular one interesting enough.


  • Dimensions – 14.7 x 11.8 x 3.4 inches
  • Weight – 2.3 pounds

Hitachi N3804AB3 – The Basics

If you’re a devoted furniture restorer, this model is the right choice for you. While it can tackle other projects without many issues, furniture restoration is its primary field. Also, it doesn’t matter how experienced you are because it’s great both for professionals and beginners. The professionals love its precision and piercing power, while beginners appreciate the ease of use.

Because it’s a pneumatic tool, it does require an air compressor in order to work. However, thanks to the modern technology, it doesn’t need a super-expensive one. Therefore, if you don’t have an air compressor, purchasing one won’t damage your budget much. In fact, any affordable compressor that can deliver up to 120PSI should be fine.

Hitachi N3804AB3 Features

The design

As far as the design goes, it’s not bad. The ergonomic handle features a rubber coating which ensures a firm grip and stability. As you may know, stability is one of the most important things safety-wise. In simpler words, an unstable unit can be a potentially deadly instrument if you don’t know how to use it.

The fact that it weighs only 2.3 pounds makes it ideal for anyone who’s ready to tackle a project, regardless of their age or gender. The trigger isn’t as sensitive as one would expect. Therefore, you won’t have to worry about sudden discharges or accidental trigger squeezing; it’s pretty firm and stiff.

Depth adjustments

This feature isn’t a rarity per se, but it’s always welcomed by devoted DIY enthusiasts. It lets you fine-tune the desired depth and keep it that way as long as you want. Once you need to change the penetration depth, all you have to do is – push a button. Instead of having to unscrew the base and hassle with different tools, this tool-free feature lets you make adjustments in a matter of seconds.

Adjustable exhaust port

If you ever had a chance to use pneumatic tools, then you probably know about air leaks. It’s a perfectly normal occurrence, but a vast majority of staplers don’t have the mechanisms to fight against such nuisances. It leads to the lack of power which consequently causes a loss in penetration, and so on.

Luckily, the integrated 360-degree exhaust port lets you fine-tune the valve so that it creates a vacuum and doesn’t leak any air. Remember, finding the right intensity will improve the stapler’s overall efficiency and performance.


Things we liked about it

The first and most obvious thing is its ease of use. As we already said, many people are reluctant when it comes to investing in pneumatic tools due to their complexity. However, you don’t have to worry about that because the Hitachi N3804AB3 is as simple as it can be. All you have to do is read the user manual, connect it to a source of power, and you’re ready to go! Remember to wear safety equipment at all times, regardless of your expertise.

The 360-degree exhaust port is also an advantage that’s worth mentioning. Although a lot of people consider it to be quite irrelevant and redundant, the devoted professionals know how useful it is, and many of them appreciate this feature a lot because it saves time and nerves.


Things we didn’t like

Even though Hitachi is a well-known brand, this particular model has a few shortcomings. The biggest disadvantage is the frequent jamming. Although it’s not an unimaginable burden, the lack of anti-jam mechanism makes the unjamming of this model a stressful experience. It seems that the spring responsible for pushing the nails tends to malfunction from time to time.

Because it doesn’t have the anti-jamming mechanism, the price doesn’t seem quite right. There are cheaper models on the market with the same features. The only difference between those and this one is the brand. Therefore, if you don’t have a problem with using a no-name brand unit, feel free to go with that. However, you’ll lose favorable warranty conditions by purchasing a no-name copy. Also, don’t count on any customer support if you opt for a less-known brand.

What Users Say About The Hitachi N3804AB3

As far as the users go, the opinions are mainly positive. There are some negative reviews, but it’s expected, especially when pneumatic tools are in question. A vast majority of people who used it say it’s not bad, but far from impressive. The main reason for that is, as we already said, frequent jamming.

Hitachi N3804AB3


If you’re planning a massive project, you might want to keep searching. The Hitachi N3804AB3 model will do the job, but it will struggle with larger tasks. Therefore, it’s good for occasional repairs, but not recommended for professional use on a daily basis.

The Hitachi N3804AB3 is a lightweight, simple, and somewhat affordable tool. Those three elements are the things you should look for in any other model on the market. Therefore, it’s safe to say the N3804AB3 is a worthy investment.
