What happens to the RPMs and torque as the size of a power drill increases?

Slower RPMs and higher torque
Faster RPMs and higher torque
Slower RPMs and lower torque
Faster RPMs and lower torque

The correct answer is: Slower RPMs and higher torque

As the size of a power drill increases, the design and functionality of the drill typically evolve to accommodate larger tasks and heavier materials. Larger drills, often equipped with more powerful motors, tend to operate at slower RPMs while delivering higher torque. This is because higher torque is necessary to handle the increased resistance encountered with larger drill bits or tougher materials. Slower RPMs allow the drill to exert a greater force without causing damage to the drill bit or the material being drilled. Conversely, smaller power drills often operate at higher RPMs but generate less torque, which is more suitable for lighter tasks. This relationship between size, RPM, and torque is fundamental in understanding the capabilities and limitations of different power drill types and is crucial for selecting the appropriate tool for specific applications.
