Final Answer:
The pneumatic tool used to remove rust and paint from metal is the Needle impact scaler. Option C is the answer.
Explanation:
Among the options provided, the correct choice is option 3, the Needle impact scaler. This pneumatic tool is specifically designed for surface preparation tasks, including the removal of rust and paint from metal surfaces. The Needle impact scaler operates by delivering rapid, repetitive impacts through a set of needles, effectively breaking and removing rust, paint, and other coatings from the metal substrate. The needles strike the surface with high frequency, facilitating the cleaning process without causing significant damage to the underlying metal.
While other pneumatic tools like air hammers, pneumatic drills, and air chisels serve different purposes, the Needle impact scaler is the most suitable for the described application of rust and paint removal.
Option C is the answer.
