What type of drill is expected to be more powerful and larger for certain materials?

Electric drills are designed to be more powerful and can handle larger and tougher materials compared to other types of drills. They typically have a motor that provides consistent torque and speed, making them suitable for heavy-duty tasks such as drilling into concrete or thick metal.

Wood drills, while effective for their specific purpose, do not have the same power or versatility as electric drills. Small hand drills are generally manual and provide less force, making them inefficient for larger projects. Cordless drills offer flexibility and ease of use without being tethered to a power source, but they may not possess the raw power or battery longevity needed for demanding materials, especially in comparison to electric drills plugged into a wall outlet. Thus, while all options serve different functions, electric drills stand out for their capability in handling heavier duties and larger materials.
