Hitachi has added plenty of new features to this item. Some are so much useful. The addition of a newly redesigned head guard allows you for a faster and easier disassembly process. It also weights low but provides you a power nailing experience. The selection of switch change gives you the benefit of quickly change between bump or sequential fires. For fastener replenishment, you can now use the help of a two-step loading feature that will make your work quicker and reduce your downtime. Let’s talk about it in detail.

Addition of new head guard

The head guard allows you for quicker disassembly during the maintenance of tools. It also adds some extra good look to it in my opinion.


It may seem to you that it’s a normal farming nail with which you cannot do any heavy work. But you will be wrong when you have started to work with that. It’s a beast. Can nail with enough power though it weighs only around 7.5 pounds. It is very minimal, lightweight, easy to lift and you will get a good handling grip while one hand was working.

Selection of switch

The selective actuation switch allows the transitions between sequential and contact nailing quick.

Nail Types

Hitachi nr90aes1 uses a 21-degree angle to nail. It is the most common nail degree of every nailing gun though. You can drive 2-3.5 inch nails easily without having any issues. And you will get the two-piece magazine in use with a total nail capacity of 64.

​Replaceable Magazine

You cannot get this feature on each of the nailing guns. But if you are a professional or have experience in this nailing work before, you can understand how bad it is for a nailing gun falling from a high height. If that happens, that means the end of that gun 99% of the time. This Hitachi NR90AES1 Plastic Collated Framing Nailer allows you to replace the magazine easily which may prevent drops harmless in most circumstances.

​Driving modes

You will be not only able to change the depth with ease but also able to change the driving mode of Hitachi nr90. You will get both the single and multiple firing modes. It would be better to switch this nailer to rapid-fire for nailing quickly when you are in commercial work.

Open nose design

This feature provides you easy access to clear nail jams. So you will not any hassle cleaning up the tools.


One thing that I like most about an air-powered nailer is that it keeps its noise very low. It gives me the fluency and efficiency of my work. I think this is the major feature Hitachi has added to this gun over the gas-powered models which are very loud.
