Hitachi NV65AH 2-1/2-Inch Coil Siding Nailer Review

Hitachi NV65AH 2-1-2-Inch Coil Siding NailerCustomer reviews: 4.3 Stars (4.3 / 5)

Nailing together fence boards, cement boards, siding, packaging and deck railing no longer means painful hammering or lugging heavy nailers around all day. The Hitachi NV65AH is a lighter nailer than most (at 4.6 pounds) with a well-balanced design to help professional users as well as amateur home builders/renovators shoot nails easily.

Made by a brand known for its professional quality power tools, this coil nailer is somewhat on the higher end with prices ranging between $249 and $397. This may make it expensive for the occasional user, but for regular users it is a worthy investment for the hours saved and ease of use.

Nail Siding And More Swiftly All Day

The air powered Hitachi NV65AH coil nailer is a nailer gun that drives 1 1/2 inch to 2 1.2 inch plastic or wire coil siding nails, allowing great flexibility in the projects that can be undertaken with the gun. Its applications are by no means limited to siding and trim. Users have used the Hitachi nailer with smaller nails (as long as they are coil nails with normal heads) since the nail tray adjusts to different lengths. The gun is just as suitable for fencing as it is for installing Hardipanel or other fiber-cement products. It can also be used for attaching wall and roof sheathing, decking, crate and pallet construction as well as mobile home and modular home construction. The NV65AH by Hitachi is a pneumatic nail gun, ideally powered by air pressures of between 70 to 120 psi through a 3/8 inch air inlet, making nailing faster and easier than a standard electric nailer and significantly faster than a frame hammer. There are several other features that the NV65AH offers users for professional quality nailing.

Ge Flush Nail Every Time

The most prominent feature of the Hitachi NV65AH is the adjustable drive depth, which helps to ensure that every nail penetrates to the same depth every single time. The adjuster provides great accuracy in dialing in the depth to which the nails will be driven. It is absolutely essential in some cases, especially for cement board siding or cedar, that the correct drive depth is maintained, which makes this nailer a boon to own.

Easy Grip, Light And Flexible

A comfortable rubber hand grip and a no-mar tip that doesn’t damage surfaces make this nailer a breeze to use all day. At 4.6 pounds, it weighs at least a pound lighter than most other pneumatic nail guns, and you can certainly feel the difference when you use your gun all day.

With its specifications and features, the advantages of the Hitachi NV65AH siding nailer are evident. It is a lightweight yet powerful siding gun that is comfortable to use even with one hand. The nailer lets you make quick and easy nail depth adjustments so that you can effortlessly fire away on siding and not have to pull out a hammer to fix proud nails.

The Hitachi NV65AH pneumatic nail gun is gives you two different firing options. Intermittent firing option lets you use the nail gun trigger to control firing. The continuous firing option lets you sink a nail each time the nose cap meets the work surface, so that you can cover large areas with great ease.

The light weight and ease of maneuvering means is possible because of the great balance of the nailer, unlike most other coil nailers. It is not nose heavy, and is very comfortable to use all day if needed.


Even a seeming flawless product like the NV65AH siding coil nailer by Hitachi must have its flaws. The major issue that most users have had with the gun is that the single shot upgrade kit, which is available separately, is not included within the price of this nailer. The nail gun fires multiple nails so smoothly that it can be a little intimidating for those who don’t know their way around with nailers. Of course the upgrade kit can be purchased to fix this issue.

Another problem a handful of users have faced is that the plastic shield keeps falling off. This is a minor flaw in the few cases it has occurred, and can be fixed with a shield replacement.

Currently this Hitachi nailer has earned 53 customer reviews with an average rating of 4.3 out of 5, indicating that all customers have rated it between 4 and 5 stars.

If you are looking for a professional-quality light air powered coil nailer for siding, fencing etc. that is easy to use all day and lets you accurately adjust the depth of nail drive, the Hitachi NV65AH is the ideal nail gun for you.
