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 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.

Cons Of Metabo HPT NT65MA4 With Solution

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.

Frequently Asked Question (FAQ)

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?

Yes. You can use any generic nail length 1-1/4 to 2-1/2 inches in this NT65MA4 nailer, including Senco or Grip-Rite, with no issue.
