Working of a screw gun:

A screw gun sets screws' bugle heads just below the drywall paper surface. The tools' positive clutches engage when pressure is applied to the Phillips bit and release when the pressure releases. You can adjust the screw bit depth and how deep it sets screws. As a screw gun sets each screw to the correct depth adjustment, the screw pulls the panel tight against the framing as pressure from the nosepiece pushes against the drywall. The screw head spins against the paper as it sinks, leaving a slight dimple and a clean, smooth edge around the head. When the screw reaches its proper depth, the clutch disengages. To use a screw gun properly, hold the tool firmly as you drive each screw. That way, your hand and forearm absorb most of the stress. Your wrist should almost align with the nosepiece, and your thumb, index, and middle fingers ride along either side of the motor housing. Pull the trigger and push the tool forward with a punching motion. That engages the clutch, starts the screw rotating, sinks it, and disengages the clutch in a fraction of a second. If you don't maintain pressure on the tool after engaging the clutch, the screw won't set properly.

Variable speed:

If a screw gun is exclusively used for installing drywall, you might think it doesn't need a variable-speed switch. It's cheaper to manufacture a tool with a single-speed switch, but equipping a drywall screw gun with variable speeds gives it a soft-start feature that can increase the motor's life. This is especially important if a user turns a screw gun on and off as each screw is inserted, instead of locking the trigger on.
