A power screwdriver is a tool designed to drive screws quickly and efficiently. It uses an electric motor to rotate the screwdriver bit, making it easier to insert or remove screws compared to manual screwdrivers. Power screwdrivers come in various types, including corded and cordless models, allowing for flexibility in different work environments. These tools often feature adjustable torque settings, which help prevent over-tightening and damage to materials. Many power screwdrivers are compatible with various screwdriver bits, making them versatile for different tasks. They are commonly used in construction, woodworking, and home improvement projects.
