Definition
A power-driven cutting tool that uses a continuous, flexible steel blade looped around two or more rotating wheels. The blade has teeth along one edge and travels in one direction past the work area, allowing straight or curved cuts to be made in metal, wood, plastic, or composite materials used in aircraft construction and repair.
Plain English
A shop tool with a long loop of toothed metal that runs around two wheels at high speed, letting you cut shapes out of sheets or blocks of material.
Context Anchor
Seen in aircraft maintenance shops, repair procedures, and fabrication instructions when material must be cut to shape.
Derivation
Named for its blade shape: a continuous 'band' of steel, as opposed to a flat reciprocating blade. The word 'band' here means a long, narrow strip joined end to end into a loop.
Why Pilots Care
The term tells you the work involves powered shop cutting equipment, not a small hand saw. That matters for safety around maintenance areas and for understanding how parts or repair pieces are made.
Intuition Check
Do not picture a handheld saw moving back and forth. A band saw uses a continuous blade loop that moves around wheels while the material is guided into it.
Example Sentence 1
The mechanic used the band saw to cut a section of aluminum stock for the repair patch.
Example Sentence 2
After laying out the template, she fed the composite sheet slowly into the band saw to produce a clean curved edge.
