Can a Cordless Screwdriver Be Used as a Drill? Expert Tips

Setting up furniture or hanging shelves often starts smoothly until a cordless screwdriver struggles to make even a small pilot hole. Many DIYers pause mid-project, asking the question: can a cordless screwdriver be used as a drill?

The answer isn’t always obvious because both tools look similar at first glance. A cordless screwdriver is lighter, smaller, and designed primarily for driving screws, while drills deliver higher torque and speed for tougher materials.

Homeowners like the idea of using one compact tool for multiple tasks. If a cordless screwdriver can handle light drilling, it saves money, storage space, and setup time for smaller projects.

Research shows most cordless screwdrivers operate between 4–12 volts, while standard cordless drills start around 14–24 volts (Engineering Toolbox). This voltage gap explains why drills handle dense materials like hardwood or masonry better.

Torque ratings tell a similar story. Drills produce far more rotational force, making them suitable for boring holes into wood, metal, and sometimes concrete when combined with the right bits and settings.

Still, there are scenarios where a cordless screwdriver doubles as a low-power drill. With the right accessories and techniques, it can make pilot holes in softwood, thin plastic, or lightweight DIY materials without damaging surfaces.

This guide explores the technical differences, ideal use cases, accessories, safety tips, and common mistakes to avoid when using a cordless screwdriver as a drill. By the end, you’ll know exactly when it works—and when a full drill is the smarter choice.

Can a Cordless Screwdriver Be Used as a Drill? Quick Verdict

A cordless screwdriver can be used as a drill for light-duty tasks. It works best for small holes in soft materials such as thin wood, plastic, or drywall when paired with the correct drill bits.

However, it lacks the power, torque, and speed to handle denser materials like hardwood, metal, or concrete. Standard cordless drills provide far better performance for heavier drilling applications.

Cordless screwdrivers typically operate on lower voltage batteries, which limits rotational force. This affects drilling depth and speed, making them more suitable for delicate or low-resistance projects.

Adapters like hex-to-chuck converters allow cordless screwdrivers to hold standard drill bits. Still, the motor strength remains the key limiting factor when compared to actual drills.

For small DIY tasks, a cordless screwdriver may save time and reduce fatigue. For anything beyond light drilling, investing in a proper cordless or hammer drill delivers better results.
