Best Cordless Drills for Drilling Through Steel Studs

Steel studs are thin compared with structural steel, but drilling them still demands a drill that runs smoothly at low speed and a bit made for sheet metal. A compact 18V or 20V cordless drill is usually the right buy. You do not need a high-torque hammer drill, and using one aggressively can tear the hole, twist the bit, or damage the stud.

What matters in a drill for steel studs

Look for a two-speed drill with a variable-speed trigger, a clutch, and a half-inch chuck if you also expect to use larger hole saws or accessories. For ordinary wiring and fastener holes, a 3/8-inch chuck can be enough, but half-inch models give you more flexibility. A brushless motor can extend runtime and usually makes a drill more capable under sustained load; it is a worthwhile upgrade for frequent work, not a requirement for a few holes.

Speed control matters more than headline torque. Use the drill’s low gear for larger holes and start slowly so the bit does not skate. For holes up to about 1/2 inch, many drills can work in high gear once the bit has started cleanly, but follow the bit maker’s speed guidance. A compact drill is easier to handle between studs and overhead; a heavier, high-torque model can be tiring and is more likely to bind hard enough to wrench your wrist.

If you already own cordless tools, staying with that battery platform is often the best value. A bare-tool drill costs less than a kit, but only makes sense if you have a compatible battery and charger. Otherwise, compare the full kit price and battery capacity—not just the drill’s advertised voltage.

Drill types compared

What to buy

For a first cordless drill, choose a compact drill-driver kit with a 1/2-inch chuck, two speeds, and a battery around 2.0 to 4.0 amp-hours. A smaller pack keeps the tool light; a larger pack is useful when you are drilling many holes or already use it in other tools. Check that the kit includes a charger, and confirm the battery belongs to the platform you intend to keep using.

For occasional home projects, a brushed drill from an established cordless platform can be perfectly adequate. Spend the difference on sharp bits and a spare battery only if your work justifies it. If you routinely drill dozens of holes, work in cramped framing, or use hole saws, a brushless drill with better low-speed control is a more sensible upgrade. Compare compact cordless drill-driver kits and brushless drill-driver kits within your preferred battery system.

Bits and technique for steel studs

Use sharp bits intended for metal. High-speed steel (HSS) twist bits are a practical choice for common small holes; cobalt bits cost more but can hold up better with harder metal and repeated use. Step bits are useful for clean, larger holes in thin sheet, especially when you need several sizes in one opening. Avoid using a wood spade bit or a masonry bit: they are the wrong cutting geometry for thin steel.

Mark the hole, then use a center punch to make a small dimple. This helps keep the bit from wandering across the smooth surface. Clamp or support the work where possible, keep the drill square, and start at low speed with steady pressure. Let the bit cut; excessive force can overheat it, dull the edge, or suddenly pull the drill through when it breaks out. For a larger opening, make a pilot hole if the bit maker recommends it, then step up gradually or use a step bit.

Do not use hammer mode on steel. It is intended for masonry and adds impact that does not help cut sheet metal. If the drill has a clutch, set it aside from driving screws: drilling should use the drill setting, not a low clutch number. On thin studs, stop when the bit clears the metal rather than pushing through with full force.

Common problems and safer work

If the bit squeals, smokes, or turns blue, stop. The likely causes are excessive speed, a dull bit, too much pressure, or inadequate lubrication for the bit and material. Let the bit cool, inspect it, and restart slower with a sharp cutting edge. Cutting fluid can reduce heat and wear, but use it sparingly and keep it away from wiring, finished surfaces, and materials that must remain clean.

A bit can catch as it exits a hole, especially when using a large twist bit. Keep both hands on the drill when the setup allows, brace your stance, and avoid placing your hand behind the stud where the bit may emerge. Wear eye protection: thin metal can leave sharp burrs and small chips. Deburr the opening, and use an appropriate bushing or grommet where cable passes through metal so the edge cannot abrade insulation.

Choose for the work you actually do

For a handful of small cable or screw holes, a basic compact cordless drill and sharp HSS bits are enough. For repeated drilling, favor brushless construction, controlled low-speed operation, and batteries already shared with your other tools. If access is the main problem, consider a right-angle drill rather than buying the largest drill you can find. The best choice is the lightest drill that handles your hole sizes comfortably and fits the battery platform you plan to keep.
