How do you use a self-drilling screw for metal?
Place a self-drilling screw into the hex head adapter. Depress the trigger of the drill slowly, while the drilling tip of the screw rests against the metal. Increase the speed of the drill when the screw finds its center. Stop drilling when the head of the self-drilling screw tightens against the surface of the metal.

With the ability to drill into steel up to 1/2″ in under 40 seconds, you will find many uses in install and service work.
Will self-tapping screws go through sheet metal?
The Self-Drilling Screw While self-tapping screws will tap a hole into a soft material, self-drilling screws are capable of drilling a hole into anything from sheet metal to wood. This key difference is self-drilling screws have a tip like a drill bit, so they do not need a pilot hole.
Do self-tapping screws come loose?

What type of screw should I use to join sheet metal parts?
The following factors affect the selection of the type of screw to join sheet metal parts. Experts recommend self-tapping fasteners for hard materials ( CRCA, SS), whereas machine screws are the best choice for softer materials such as Aluminum. Self tapping screws require larger sheet thickness to engage the recommended number of threads.
