Screw guns are similar to the power drill, at least in appearance. There are two basic types. Some screw guns are designed for drywall installation, some for general construction purposes. A drywall screw gun will turn as high as 4,000 RPMs, while a screw gun designed for larger screws and other fasteners, also known as drivers, will turn around 2,500 RPMs. These drivers generally have a high-current motor as well, giving them more power for working with larger fasteners. Using a drywall gun to drive a 4-inch screw into framing materials would be over working the tool, but is no problem for an impact driver.
A drywall screw gun is a tool used to install drywall. Screw guns look like a normal drill although they have a "nose" as opposed to a chuck. The nose holds an interchangeable 0.25 inches (6 mm) shank bit, commonly known as a tip. Most commonly used is a 1 inch (25 mm) #2 phillips.
The nose on both types can be adjusted to countersink screws to desired depth. Pressure must be applied to the bit in order to engage the clutch and drive the screws. Some screw gun users like to keep their motor running constantly, while installing drywall, and this practice is recommended by manufacturers. Some screw guns auto-feed screws from a clip. Decking screw guns have a long handle so the user does not have to bend over.
