Hitachi Metabo HPT NR83A5 Pneumatic Framing Nailer Review
The above image shows the front side of the frame. You will see that it features a large hole in which you insert your nails.
There are two holes at each end of the frame, one for each nail. The nails must fit into these holes perfectly or they won’t work properly.
When you use the nailer, you have to make sure that the nails do not get stuck inside the holes. If they do, then you will lose all your hard work because the nails will become loose and fall out of their sockets.
There are three types of nails available with this nailer: flat, round and square. Flat nails are usually used for small jobs like trimming or painting while round ones are generally used for larger jobs such as installing doors or windows.
Square nails are best suited for installing door hardware.
Round nails come in different sizes from 1/8 inch (3 mm) to 3/16 inch (7.6 mm).
They are made up of six parts: a head, a base, a ring, four sides and a nose. The size of the nose determines how much pressure is applied when driving the nail through the wood. The longer the nose, the more pressure will be applied.
The ring is an important part of a round nail. It prevents the nail from snagging on materials when you are working.
The base prevents the head from splitting when it hits the surface of the material.
Flat nails are also made up of six parts: a head, a base, four sides and a nose. The nose is the only difference between a flat and a round nail.
The nose on a flat nail is shorter than the nose on a round nail
The nose of the nail is what you hit with the hammer. The harder you hit it, the faster it goes into the wood.
Hitachi Nailer Parts
Now that we know what kind of nails the nailer uses we can take a look at the nailer itself.
The handle is placed at the top and it is this part of the nailer that you hold and shoot into the wood. In the middle of the handle, there are two triggers.
The top one fires the nails and the bottom one finds them in their slots so you can remove them. There is a small hole under the lower trigger which acts as a bit for your thumbnail so you can pull out the used nails from their slots.
The magazine is a box-like part under the handle which holds the nails. It has four holes on each side in which the nails are placed.
The holes are made in such a way that only the tips of the nails are visible.
At the front of the nailer, there is an air filter and a pressure gauge. The air filter stops any dust or other particles from getting into the machine and damaging it.
The pressure gauge shows how much air is left in the machine. If it gets too low, then the nailer will stop working.
The air hose is another important part of the machine. It connects to an air compressor and carries the air to the nailer.
The hose is made of plastic and consists of several different parts. One end attaches to the compressor and the other goes into the nailer itself.
The compressor is obviously used to pump air into the machine. In other words, it fills up the air tank.
The bigger the tank, the more air it can hold and the more work you can do before re-filling it again.
The hose carries the air from the compressor to the nailer.
To sum up, here are all the parts of a brad nailer:
3. Air filter
4. Pressure gauge
5. Air hose
How a brad nailer works
The tool is operated with the help of compressed air which travels from the compressor, through the hose and into the air chamber. The pressure is regulated by a piston-like device known as a regulator.
A trigger on the handle releases a small amount of air which passes through a one-way valve, into the trigger mechanism and finally into the bottom of the firing pins.
