The most common type of power driven tap is the "spiral point" plug tap, also referred to as a "gun" tap, whose cutting edges are angularly displaced relative to the tap centerline. A spiral point plug tap ("gun" tap). This feature causes the tap to continuously break the chip and eject it forward into the hole, preventing crowding.
This helps ensure that the gun does not discharge in an unsafe manner, causing the nail to become an unrestrained projectile. Due to their potential for causing personal injury, OSHA regulations in the US require certification specific to the tool being used before any person is permitted to rent or use powder-actuated equipment.
