Cordless drill is a portable power tool used for drilling holes and driving screws into various materials without the need for a constant power source. Unlike traditional corded drills that require an electrical outlet, cordless drills are powered by rechargeable batteries, providing greater flexibility and mobility for users.

Cordless drill is powered by rechargeable batteries, usually lithium-ion (Li-ion) batteries, which provide sufficient power and longer run times compared to older battery technologies.  The battery is inserted into the handle of the drill and can be easily removed for charging.
