Detailed Features Of Metabo HPT NT65MA4 Finish Nailer

Well-Built Aluminum Body

The name Hitachi itself explains its reliability, and there is no need for further clarification. Hitachi invests adequate quality time in the development of its NT65MA4 15 gauge finish nailer without any deviation. It uses an aluminum alloy to make the body lightweight, a mere 4.2 pounds, making it convenient in your hand for a full day of work.

Also, it comes with an elastomer grip, which ensures a secure hold besides comfort. So, the way heavier models do, it won’t wear you out.


The Metabo NT65MA4 is designed to fire 15 gauge finish nails, as you might have noted. You’ll be surprised to learn that its previous edition, the NT65M2S, was designed to fire 16-gauge finish nails.

Are you curious as to why they chose a 15 gauge finish nailer? The development of 15 gauge finish nailers was motivated by the fact that 16 gauge finish nails are subtle and thinner, with less holding ability than 15 gauge finish nails.

The 15 gauge finish nailer allows you to fasten a heavy molding like a 1-1/4″-thick baseboard and trim easily and securely. Therefore, You can do more demanding woodworking tasks like nailing door jams or stairs, crown and base moldings, cabinets, and exterior trimming with it. 

To do so, Hitachi 15 gauge angled finish nailer allows you to actuate 1-1/4 inch 34-degree angled nails at 70 psi into any soft lumber like pine, and at 120 psi pressure, you can flush 2-1/2 inch pins into any hardwood like Oak with no issue. Plus, its angle magazine allows you to reach tight corners easily.

Depth Of Drive

You have to fasten various materials while doing woodworking jobs. So, there is nothing better than having a tool that supports the tool-less depth of drive adjustment. A renowned company like Hitachi knows it well and designs its Metabo NT65MA4 accordingly.

You will find a dial knob located conveniently just below the non-slip elastomer grip trigger to adjust the flash drive. The elastomer trigger also gives you improved control and a professional finish.

Easy Nailing Operation

The nailing operation is quick and simple thanks to a simple switch, which is enabled by a flip of the nicely curved selective actuation trigger. It allows you to switch from single to contact firing by simply pressing a switch upward or downward, without the need for any additional parts or equipment.

Adjustable Exhaust

A fully customizable 360-degree air outlet/portal on the top of the Metabo finish nailer head can easily steer exhausted air, as well as dirt and oil, away from the user.

With the help of this 360-degree exhaust portal, typically, you can adjust the combustion air exhaust path to prevent chewing dust on drywall while assembling the baseboard over a dusty subfloor. You can also protect your hat from flying off while fastening the door or window casing or any other finishing job by adjusting its direction.

Air Duster For Clean Work Surface

A neat and tidy workspace will give you a sense of clarity, allowing you to think more deeply about your work. To address this issue, the Metabo NT65MA4 finish nailer comes with a unique feature that allows you to quickly eliminate dust and dirt from the work surface. Yes, absolutely!

That’s the built-in air duster, which will make cleaning a lot easier for you, resulting in a cleaner working atmosphere every day. It will also help you to complete your work faster.

The air duster works by collecting air from the compressor and passing it through the nailer chamber. Then forcibly ejecting it through a hole in the machine’s front. You could easily run this device according to your needs by pressing a button.

Tool-Free Jam Clearing

Metabo finish nailer design with a clear nose with an easy-to-open latch that allows you to quickly extract nails if any jam occurs. The best part is you’ll not need to use any tools to clear it. To know more about jam clearing, you may visit our blog on how to unjam a nail gun.

Damage Protection No-mar tip

Finish nailers do mostly decorative and sensitive work, such as driving nails into soft boards or plywood, where you need a guard that protects your surface from denting by the sharp tips of the tools used.

By keeping this in mind, Hitachi includes the No-Mar tip to protect the valuable work surface from potential damage. If not needed, you can also remove it and stored it in the device for further use.

Comfortable To Use

In addition to its lightweight body, Metabo NT65MA4 covers its handle with a rubber grip that adds extra comfort and secure hold to work with it for a long day.

It comes with a pre-assembled air fitting that is angled upwards to keep the hose out of the way of the user and workpiece while driving nails. Therefore, you can enjoy hassle-free nailing.

Limitation Of Metabo HPT NT65MA4

The overall performance of this 15 gauge finish nailer is excellent and difficult to find any flaw except dry-fire lockout system and lack of belt hook.

Problem 1: Lack of belt hook

A belt hook is needed when you drive nails in odd positions or when you need both hands free. So, it’s undoubtedly a backlog of this system. We hope Hitachi will understand this and bring a correction in their design soon. Nevertheless, you can fix a belt hook by visiting your closer workshop/hardware shop if you often need to use this facility.

Problem 2: No dry-fire lockout system

Absent dry-fire lockout can cause damage to the working surface as well as reduce the life of the unit. Although it doesn’t have a dry-fire lockout feature, you can use the magazine window to gauze the endpoint of the nail strip. Whenever you find low nails in the magazine, you need to quit nailing and reload a fresh strip to continue your work.

How To Use Metabo HPT Finish Nail Gun?

Here are some general steps on how to use the Metabo HPT Finish Nail Gun:

1. Prepare the nail gun: Before using the nail gun, make sure it is properly assembled and lubricated. Check the user manual for specific instructions on how to do this.

2. Load the nails: Open the magazine and insert the nails into the nail gun. Make sure the nails are properly aligned and seated in the magazine.

3. Adjust the depth: Depending on the type of material you are nailing, you may need to adjust the depth of the nail. This can usually be done using a depth adjustment wheel or knob on the nail gun.

4. Position the nail gun: Hold the nail gun firmly and position it at a 90-degree angle to the surface you want to nail.

5. Fire the nail gun: Press the trigger to fire the nail gun. Make sure to keep your fingers away from the firing area and wear appropriate safety gear, such as eye protection and earplugs.

6. Repeat: Continue firing the nail gun, moving it along the surface as needed, until you have completed your nailing task.

7. Unload the nails: When you are finished, remove any remaining nails from the magazine and store the nail gun in a safe place.

Note: These steps are general guidelines and may vary depending on the specific model of the Metabo HPT Finish Nail Gun. Always refer to the user manual for detailed instructions and safety guidelines.

Frequently Asked Questions For Metabo HPT NT65MA4 Finish Nailer

What is the difference between 15ga and 16ga finish nailer?

The difference between a 15ga and 16ga finish nailer lies primarily in the size of the nails they can accommodate. A 15ga finish nailer is designed to handle nails with a diameter of 0.072 inches or 1.829 mm, while a 16ga finish nailer is capable of driving nails with a diameter of 0.0625 inches or 1.588 mm.

This may seem like a small difference, but it can have a significant impact on the quality of your finished project. The 15ga nailer is typically used for heavier trim work, while the 16ga nailer is better suited for lighter, more delicate trim. It’s essential to choose the right tool for the job to ensure a professional and polished finish.

What Capacity Compressor Does It Need To Run Efficiently?

The size of the compressor depends on the pressure, air consumption, and the number of equipment running at a time. Therefore, you can calculate your air compressor size by using the following formula.

Amount of Air Required = number of nailers x average nails driven each minute per nailer x air consumption at given air pressure x safety factor (1.2 always)

For Example: Let’s assume, you run two nailers at a time and drive 30 nails per minute with 100 psi air pressure. Then the required size of the air compressor will be

Amount of air required to run two nailer = 2 x 30 x 0.045 (1.29) x 1.2 = 3.24 CFM (ft3/min) or 92.88 liter/min

Therefore, you need an air compressor that can produce 3.24 CFM air to run two nailers simultaneously.

Does Hitachi Sell Its NT65MA4 Finish Nailer In A Hard Case?

Yes. It comes with a beautiful and slim hard case to store or transport your device securely.

Is It An Oil-Free Device?
