Recently metal studs have gained popularity for their use in new residential and commercial construction works due to their high resilience, durability, and better cost-effectiveness. Sometimes, drilling is the only way out when we come across metal studs to hang something onto it or mount a TV. Show
How to drill into metal studs? Start with locating the stud in your wall using a stud finder. Locate the edges to find the center and mark your drilling spot. Use sharp titanium, cobalt, or carbide-tipped twist drill bit with a medium torque drill for a cleaner hole in the metal stud. Only use toggle bold or drywall screws into the drill holes. Although wood studs are superior to metal ones aesthetically, a good paint job can make them quite difficult to distinguish. Before we jump into the complete procedure on how to drill into metal studs, let us briefly discuss the pros and cons of metal studs. Pros of Using Metal Studs
Cons of Metal Studs
Drilling into metal studs is not quite different than drilling through a simple metal. The main difference lies in metal studs’ hollowness (Metal studs are hollow, whereas plain metal isn’t). Below I have discussed a stepwise approach on how to drill into metal studs. Step 1: Locate the metal stud in your wallThe first step when drilling into metal studs is to locate them. So how to find a metal stud? You can find a metal stud using a magnetic stud finder like StudMark or simply knocking your wall with your middle finger to spot a dull hollow sound. Electronic stud finders are quite accurate. You can also use your smartphone’s built-in magnetometer to locate a metal stud. I personally prefer two stud finders that are briefly discussed below.
To use a stud finder, place it on the wall and move it in a Z pattern. Once the stud hits the metal, you will either feel a magnetic pull in the case of a non-electronic stud finder or hear a beep in an electronic one. Mark the place carefully with a pencil. For the knocking method, you require a lot of experience and sharp ears. Knock the wall with the middle finger’s knuckle and listen for resonance; a dull sound will indicate a stud. Step 2: Locate the metal stud center for drilling a holeFinding the stud’s centerIt is important to locate the stud’s center because a wrong hole will compromise its strength. Electronic stud finders come with built-in functionality to find the stud center. You have to move the finder around, and it will show where the stud center is. Firstly, find the approximate edges on both sides when using a simple stud finder, then mark them with a pencil and drill a pilot hole. The resistance will guide you to the edge ( you may need to drill multiple pilot holes). Then using a scale, find out the center. Step 3: Use proper drill bit to drill metal studSelecting Drill BitConventional twist bits can do the job but can potentially destroy the drill bit or end up with a jagged hole. I personally recommend either using titanium, cobalt, or carbide-tipped drill bits. I have personally shortlisted my favorite bits that you can find online and are best suited for the job.
It is better to start with a small-sized drill bit and then move to larger ones. Step 4: Drill at low Speed and avoid hammering while drilling into metal studsTo drill into metal studs, it is better to keep the speed low. This is because high rpm will heat up the bit and hence damage it. The ideal rpm should be between 700 and 1000. It is also recommended not to use the hammering feature when drilling into metal studs (this creates unnecessary dents). Step 5: Use the Right Screws with metal studsEvery screw is not designed for use in a metal stud. If you are drilling metal studs to hang drywall, you are wrong. Hanging drywall doesn’t require pilot holes. Specially designed fine drywall screws (they are self-drilling) will do the job nicely. If you are drilling metal studs to hang a heavy object such as a television, always use toggle bolts. They have a self-locking mechanism and are designed to bear the load. Toggle boltsCan I use my iPhone as a stud finder?Yes! You can actually use your iPhone to locate a stud. There are plenty of applications that utilize the iPhone built-in magnetometer to locate a stud. Although they are not foolproof, when used appropriately can do the job. Can a cordless drill go through metal?Yes! You can drill into metal using a cordless drill. All you have to do is select the right type of drill bit mainly, cobalt and titanium. Thanks to mechanical gears, cordless drills nowadays have power similar to a wired drill. How far should a screw go into a stud?For good results, a screw should ideally pass 2/3rd of its length deep into the stud. This also depends on the strength required and the thickness of the stud. Can you screw into a metal stud?Recently, many contractors have begun using them in residential homes as well. Metal studs are stable and sturdy for both load-bearing and non-load-bearing walls. However, most screws will not penetrate through metal studs. Often, contractors have to use special screws for metal studs due to the material's durability.
Should you always drill into metal?Drill at a Slow Speed
In general, it's a good idea to drill through metal using as slow a speed as possible using a drill bit for metal. Hard metals like steel and larger drill bits require even slower speeds. With a small twist bit (1/16 in. to 3/16 in.), you can drill through most metals at 3,000 rpm.
How do you anchor into metal studs?Attaching drywall to metal studs is the best done with Fine Thread Drywall Screws. Fine-thread drywall screws do not hold as well in wood as do coarse-thread screws. Installing drywall to metal/steel stud require fine threaded drywall screws so that it is easier to drive the screw through the metal.
Do you need special screws for metal studs?Choose the right screws
Don't use drywall screws to screw your studs together—they're not designed for that. Pan-head framing screws work best. Concrete screws work great to attach the bottom track to the floor.
