What Are Electrical Power Tools?

Electrical power tools are mechanical devices that operate using electrical energy—either through a direct connection to an outlet (corded) or powered by rechargeable batteries (cordless). They are designed to perform tasks that would otherwise require extensive manual effort or time, such as drilling, cutting, grinding, sanding, polishing, and fastening.

Power tools are categorized based on their energy source:

• Corded Power Tools – Plug into a power outlet

• Cordless Power Tools – Operate on battery packs (usually lithium-ion)

Corded vs Cordless: Which Is Better?

Corded Tools

• Pros: Constant power, no need to recharge

• Cons: Limited mobility due to cables

Cordless Tools

• Pros: Portability, flexibility to work anywhere

• Cons: Limited battery life, often less powerful

Best choice? For mobile or on-site tasks, cordless is often more convenient. For heavy-duty, continuous work, corded tools are usually the better option.
