HITACHI NT65MA4 15 Gauge Finish Nailer / Review 2018



The HITACHI NT65MA4 15 Gauge Finish Nailer is a nailer that does all the work for you. Very similar to the Porter Cable with placement of mechanisms and layout. Very easy to load nails in the back of the gun and magazine area is plastic. Some may have a problem with the magazine being plastic, but it does not bother me.

Worked like a charm right out of the box. Lightweight, fast, and powerful. The 15-gauge nails are heavy enough for almost any finish project. Although you can adjust the power setting on the nailer, I prefer adjusting the power level on the compressor. I ended up hanging siding with this nailer to hide the nail patterns and the 2-inch nails were exceptionally strong.

Got a jam? Just lift of and expose the driver for easy-to-clear nose for quick nail extraction in case of a nail jam.  A selective actuation switch that allows for either bolt firing or single firing nailing with the easy flip of a switch.


The rubber grip adds comfort while you work, plus its exhaust portal directs pesky air exhaust away from you.

The selective actuation switch allows for either sequential or contact nailing with a simple flip of the switch. Its 360-degree, fully adjustable exhaust portal direct air exhausts away from you, plus its compact size minimizes fatigue while increasing maneuverability.

The removable no-mar tip protects the work surface from damage while the rubber grip adds comfort. It accepts 15-gauge nails from 1-1/4 long to 2-1/2 long.

Adjustable Exhaust: It has a 360 degrees fully adjustable exhaust that can be directed away from the user. This is done to ensure that air exhaust, debris and oil are avoided.

Portability: The finish nailer is portable because it is not large in size and it is not dependent on a permanent power source or anything that limits its portability. It weighs 4.2 pounds only and thus it is easier to carry around. Perfect for moving from one room to the other.

Ease of Use: This finish nailer is easy to use and it also comes with an owner’s manual for recommended use and maintenances. The handles also make it easier to use as the owner does not strain when using the nailer easing fatigue. It even has a very nice grip for a woman to handle.

Rating and Capacity: This HITACHI NT65MA4 15 Gauge Finish Nailer has a capacity of driving in more than 1000 nails before any maintenance is checked. It is air powered thus making it simple to move with. It is meant to be a portable nailer.

Special Features: It has selective actuation which allows for either sequential or contact fastening with no additional tools required. It also has an air duster. This allows air from the compressor to bypass the nailing function and expel from a hole in the front of the tool. The user can clear away debris and dust from the work surface in preparation for nailing or gluing or just do clean up; saving time and energy.

Job Suitability: This one is for the big boys. Not suitable for small scale jobs.

The finish nailer has its own unique quality features and it would get a perfect score if not for its little user problems like jamming nails if you put the ones that are not recommended by the manufacturer.
