Nail gun

From CosplayWiki

A nail gun or nailgun is a type of tool used to drive nails into wood or some other kind of material. It is usually driven by electromagnetism, compressed air or a small explosive charge. Smaller nail guns are often called brad, or pin nailers. Nail guns have in many ways replaced hammers as tools of choice amongst builders.

Nail guns also have many advantages over hammers, as they drive the fastener instantly, without splitting the wood, and consistently setting the nail head below the surface.

For safety, nail guns are designed to be used with the muzzle touching the target; they are short-range and wildly inaccurate if a user tries to use one as a projectile weapon. Explosive powered, or "powder actuated" nailguns fall into two broad categories: direct drive, or high velocity devices; and indirect drive, or low velocity devices. These categories differ in as much as the direct drive nailer uses gas pressure acting directly on the nail to drive it, and the indirect drive system uses gas pressure acting on a heavy piston which drives the nail. Indirect drive nailers are safer because they cannot launch a free-flying projectile even if tampered with or misused, and the lower velocity of the nails are less likely to cause explosive shattering of the work substrate. All kinds of nailguns can be dangerous, so safety precautions similar to those for a firearm are usually recommended for their use.
