Definition
A handheld power tool driven by an electric motor that turns a chuck holding a drill bit or other rotary cutting attachment, used in aircraft maintenance for drilling holes, removing fasteners, and driving abrasive or polishing accessories.
Plain English
An electric power drill — the kind a mechanic uses to drill holes or run a bit at the end of the chuck.
Context Anchor
Seen in aircraft maintenance, repair, and metal-work procedures where holes must be drilled accurately.
Why Pilots Care
Drilling into an aircraft part must be done with the correct tool, bit, speed, and approval; a poorly drilled hole can weaken or damage the part.
Intuition Check
Do not read motor here as an aircraft engine. In this term, motor means the electric part inside the tool that makes the drill bit spin.
Example Sentence 1
The mechanic used an electric drill motor to remove the damaged rivets from the wing skin.
Example Sentence 2
A low-speed electric drill motor prevents overheating when drilling through thin aluminum skins.
