Air nailers have the ability to fire nails quickly and repeatedly, enabling carpenters and house-builders to fire thousands of nails in a day. Imagine trying to do all that with a hammer! Everything from stud framing to roofing to exterior plywood sheathing can be fastened using air nailers, making it possible to put houses up very quickly.

One of the biggest leaps we have made in terms of speed is the invention and production of pneumatic, or air tools. Nowadays, with the help of a good air compressor and a few choice air tools, house building and even furniture making has become significantly less time-consuming. Prices are also affordable to where DIYers and hobbyists often have their own collection.

We have come a long way since the days when man toiled long and hard under the beating sun with only simple hand tools such as a hammer and chisel as his companion. Carpentry and woodworking used to require considerably more skill in days gone by, before the invention of modern electronic tools. Don't get me wrong, it's still no walk in the park, but in comparison, we can do a lot more with less knowledge and in significantly less time.

Nail guns are most commonly used by house-builders to put together wooden framing and the plywood sheathing which makes up the floor, wall, and roof base. Nail guns can be used to fire nails either straight into the work piece or diagonally, in the case of attaching perpendicular boards. For example, a vertical board can be firmly fixed to a horizontal one by firing several nails diagonally through the vertical board and into the horizontal one.

Most professional house-builders use guns that fire between 50 and 75 millimeter nails. However, most high-end nail guns will only be made to fire one or maybe two sizes. The more "universal" a nail gun is - as in, made to accommodate several sizes - the shorter its lifespan will inevitably be. This is why nail guns that can fire a whole slew of sizes are often found in the workshop of a DIYer, but often absent from that of a professional's.

The two can be told apart by the jack size, with normal having a bigger opening. You should make sure you have the right compressor for your tool/s. Of course, the better compressors will have both air pressures, but cheaper ones will usually only have normal air pressure. Normal air pressure will normally be between 0.7 and 1 megapascal, while high would be in the 2.5 to 4 megapascal range.

However, as the name may or should suggest (nail gun), there are certain safety rules and tips people should know before attempting to use these awesome tools. Even with all the safety features built into these tools, pneumatic nailers remain the number one cause of power tool related injuries where patients get sent to the ER. In fact, about 37,000 people are admitted to the ER per year in the US alone! Scary stuff huh?

Although there are many kinds of air tools, we'll be sticking to air nailers in this article due to it being not only the most commonly used, but also the tool that is responsible for the more serious injuries. There are many different kinds of air nailers as well as staplers and tackers, but the one thing they have in common is that they all fire some sort of projectile, making it extremely dangerous if not used safely.

Professionals often use a single length for whole days, and need their tools to be reliable and durable. On the other hand, DIYers may or may not use it once a week, and probably won't want to put out 500 to 1000 dollars for a nail gun for every size they may use. That's right, these things are by no means cheap! Not only are the nail guns themselves quite expensive, but you must also have a compressor and air hose in order to use it.

A good air compressor will also cost you a right arm, ranging from a hundred to several thousand dollars. Another thing to keep in mind is that there are two air pressures used for air tools, normal and high.

Types of Nail Guns

Finishing Nailer, or Brad Nailer - this one is used for intricate work as well as fastening stock and other materials that don't require strong attachment. Those who are familiar with nail guns know that there is substantial kick-back when firing larger nails, making precision attachment of "floating" or otherwise unstable boards rather difficult due to the sudden jolt.

Being that staples hold better than nails of the same length and girth, they are used for boards that are delicate but also require a strong hold. However, because they have relatively thin girths, they are also often used in conjunction with an appropriate bond. This tool, like the finishing nailer, is quite versatile, but leaves a more visible staple head. On the plus side, it holds better.

For example, you can use a finishing nailer to attach two boards together in a temporary fashion, eliminating the possibility of unwanted movement during attachment with larger fasteners. Splitting is another potential problem that can be avoided by using a finishing nailer. This versatile tool can be used for almost anything that is delicate and/or requires precision.

Stapler, or Tacker - I'm sure we're all familiar with hand staplers right? Well, these are simply the heavy-duty version powered by an air compressor. Tackers can fire staples generally ranging from as short as 19 millimeters to as long as 57 millimeters. Tackers are primarily used for tongue and groove boards, although they can essentially be used for anything.

Be aware of what you'll be using the tool for and what specific nails you'll be needing for the job like as pointed out here at http://toolsandall.blogspot.com. Most countries have building codes that mandate specific nail types with specific nail pitch for various components of the building.

I will list the main types of nail guns, staplers and their uses for your reference:
Standard Nail Gun - this is the kind that fires your normal nails that you would otherwise nail in by hand, with most ranging in lengths between 50 and 75 millimeters. Bear in mind that there are not only varying lengths, but varying shank diameters and head sizes.

Pin Nailer - these are used when you can't afford to have visible nail heads, as even finishing nails can be seen. Of course, the smaller the nail head gets, the less hold it will have to do its job. This is why pin and finishing nailers are often used in conjunction with a bond of some kind. Pin nails can of course still be seen by someone who knows what to look for, but it's hardly noticeable. A common use of this tool is for finishing work such as trimming and moulding.
