Powder Actuation
Explosive-powered ("powder actuated") nailguns fall into two broad categories:
- Direct drive or high velocity devices. This uses gas pressure acting directly on the nail to drive it.
- Indirect drive or low velocity devices. This 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 is less likely to cause explosive shattering of the work substrate.
Either type can, with the right cartridge loads, be very powerful, driving a nail or other fastener into hard concrete, stone, rolled steelwork, etc., with ease.

Famous quotes containing the word powder:
“Uncle Ben’s brass bullet-mould
And powder horn, and Major Bogan’s face
Above the fire, in the half-light, plainly said
There’s naught to kill but the animated dead;”
—Allen Tate (1899–1979)
