What’s the difference between an electric screwdriver and a hand drill?
Source:
Electric screwdrivers are specialized for tightening and loosening screws, with low torque (around 5 N·m) and low speed (about 200 rpm), making them ideal for precision assembly. Hand drills, on the other hand, handle both drilling and screw driving, offering higher torque (30–50 N·m) and faster speeds (up to 1,500 rpm), and are suitable for drilling into wood and metal. The specific differences are as follows:
Core Feature Differences
Electric screwdriver:
Single-purpose: Designed solely for screw fastening (e.g., furniture assembly, appliance repair) and cannot be used for drilling.
Torque and Speed: Torque is approximately 5 N·m (equivalent to the tightening force of a human hand), and the speed is ≤200 rpm, to prevent stripping screws or damaging the material.
Hand drill:
Versatility: Can drill into wood, thin metal, and ceramic tile, and drive screws, but requires the use of a drill bit or screwdriver bit.
Torque and Speed: Torque 30–50 N·m, maximum speed 1,500 rpm, suitable for penetrating hard materials.
Design Feature Comparison
Electric screwdriver:
Compact in size (fits comfortably in one hand), lightweight (often featuring a carbon‑fiber shell), and ergonomically designed.
Low voltage (3.6V–7.2V) provides long battery life, but the drilling power is insufficient.
Hand drill:
The body is relatively large and features a drill bit holder, enabling quick bit changes.
High voltage (12V–24V); some models offer adjustable torque and speed, making them suitable for various materials.
Recommended Use Cases
Choosing an electric screwdriver: For precision screw‑driving tasks—such as electronic device repair or lock installation—ensure it is equipped with overload protection to prevent damage.
Electric drill for professionals: Suitable for a wide range of tasks (e.g., drilling holes, driving expansion screws), especially when working on non-concrete surfaces.
