Question

nccer 00104 - introduction to power tools
when is a pneumatic drill commonly used?

• to perform precision work
• to drill in tight, small areas
• when electricity is unavailable
• in areas where noise is a problem

Explanation:

Pneumatic drills run on compressed air instead of electricity. So they are commonly used when there is no access to an electrical power - source. Precision work is usually done with more specialized tools, drilling in tight small areas isn't the main reason for using a pneumatic drill, and pneumatic drills are generally noisy.

Answer:

when electricity is unavailable
