Screws are designed to be self-tapping, but in many cases you may still want to drill a pilot hole. If you drill all your pilot holes at once, this process is a little less time-consuming, since you limit how often you’re changing out your drill bit.
While you can rely on the DIY "hack" of using a nail to drive your pilot hole, a cordless or corded power drill provides better results. Drills also make the installation — or even removal — of screws easier compared to a handheld screwdriver.
