*Nail Gun*

A nail gun is a tool used to drive nails into wood and other hard materials. Nail guns are available in a number of different styles and sizes, including special models for framing, roofing and sidings. Because they can replace a hammer in most cases, saving the user time and effort, nail guns have become standard among both professional and amateur builders. A nail gun is most often powered by compressed air or batteries.

The most common type of nail gun is the pneumatic nailer, which works with compressed air. These nail guns are cost-effective, easy to use and very dependable. They can be somewhat bulky because they depend on an air compressor and a trailing air hose.


There is less risk of splitting the wood grain when using a nail gun than when using a hammer. Nail guns are especially useful in delicate projects such as the application of moldings and trimwork. A nail gun sets the nail in one motion, reducing the chance of hammer marks that can ruin delicate woods. Most models also include a rubber safety nose to protect the wood from friction.

Nail guns have long been considered a safety hazard. They are powerful and dangerous if mishandled. Caution is a must when working with one.

Professional-grade varieties are automatic, and fire a nail directly upon pulling the trigger. A semi-automatic nail gun is more appropriate for beginners, since it requires a two-step process: pull the trigger and then tap the barrel against the wood. This safety feature protects the user from accidentally firing a nail gun and injuring himself or others.

For one-time jobs, a nail gun can also be rented at hardware stores and home repair centers.
