Hitachi NT50AE2 18 Gauge Finish Nailer Review

The Hitachi NT50AE2 18 gauge finish nailer is a high quality mechanical nailer with a wide range of applications. The machine gun version is equipped with a large hammer, which makes it ideal for use in combat situations where speed and accuracy are required.

The machine pistol version uses the same design but features an improved trigger mechanism to increase reliability.

In addition to its many other applications, the nailer is used in construction, mining, landscaping and many other industries. The nailer is available in various finishes such as chrome plating or black oxide coating.

The nailers are very popular among hobbyists due to their low cost and ease of maintenance. They have been around since the 1950’s when they were first introduced into military service.

Nails are manufactured from either steel, aluminum or copper. Steel nails are used for most types of household and industrial purposes while aluminum nails are commonly found in automotive and machinery applications.

Copper nails are used primarily for outdoor work like building fences, paving driveways and so forth. The nailer is powered by a motor or hand crank. Most models use a compressed air power source, which eliminates the need for fuel or battery replacements.

The price of these nailers range from as low as $ 35 to as much as $ 1,800 for the higher end professional models. Because they are high quality tools and built to last, most professionals keep and hand them down from one generation to the next.

Many people who get into woodwork, construction or other similar hobbies buy one of these tools because of their versatility and reliability.

The nailer is popular in the building trade because it can sink nails up to 60 times per minute. This makes it quicker than a traditional hammer and nail even though you have to reload the gun after every shot.

The nailer can be used for several different functions on the job site. It can be used for framing, sheathing, baseboarding, molding, door and window casing and so forth. Because the tool is so versatile, many tradesmen buy one even if they only use it occasionally on certain jobs.

The original nailer was developed in 18th century England. The earliest version of the battery was invented by a man named Sylvester Roper in 1818.

It had a crude design and was very heavy and cumbersome to use. It was so heavy that it had to be bolted to the floor. It took a long time for inventors to come up with a portable battery-powered device.

The original air compressor was introduced by a man named Roots in 1845. His design consisted of an air pump driven by the power of horses.

Later on, other inventors designed models that were powered by diesel and gasoline engines. The invention of these machines paved the way for the creation of the modern nail gun.

The first air powered nail gun was invented by a person named John Henry Kennedy in 1899. The original version of this tool weighed 55 pounds and could only shoot 30 nails per minute.

It wasn’t until 1921 when a man named James Henry started manufacturing an improved model that was lighter and more efficient. His model shot 400 nails per minute.
