How does a stud finder actually work?

Magnetic stud detectors use magnets to locate metal in the walling material because the magnet is attracted to the metal. The attraction grows stronger as the magnet gets closer to the metal in the walling. The strongest attraction point, if due to a metal fastener in the wall, should indicate the location of a stud.

How do I know if I hit a stud or a pipe?

Drill carefully through the drywall (put some tape on your drill bit at just over 1/2"), then feel your way from there. If there's a pipe at that location, you'll almost certainly feel a gap first, and even if you don't you should detect plastic or metal, and either should move somewhat when pressed.

Can an iPhone be used as a stud finder?

However, the iPhone's built-in magnetometer does allow apps to locate metal wall studs, nails, screws or any ferromagnetic material—meaning it also won't work on some types of stainless steel. ENR compared 16 stud-finding and metal-detection iOS apps.

Is a stud finder just a magnet?

Stud Finders: For a simple yet amazingly effective stud-finding solution, get a neodymium magnet. It can't detect the wood two-by-fours, but it easily locates steel screws that hold the drywall to the studs. We often use a strong XLTK-BLU magnetic thumbtack for this job.

Are you supposed to drill into a stud?

If you're drilling into a metal or steel stud, you'll need to pay special attention to the drill bit you're using. A bit made of titanium or cobalt is ideal since it is designed for heavy-duty drilling. A drywall screw is appropriate for metal studs in terms of screws.

Why can I not drill through a stud?

The earliest stud finders detected ferrous metals using compasslike pivoting magnets. Even though only commercial buildings use metal studs, magnetic stud finders, which are still available, work with wooden studs, too, by locating the metal nails used to mount the wallboard or wooden lath.
