Which component typically drives a whizzer saw?

The whizzer saw, which is commonly used in extrication scenarios due to its versatility in cutting through various materials, is typically driven by compressed air. This power source allows the saw to operate efficiently, making it effective for quickly slicing through metal and other tough materials encountered during vehicle extrication. The use of compressed air enables the saw to maintain a high RPM (revolutions per minute), ensuring that it can perform precise cuts necessary in rescue situations.

While other power sources might drive different tools used in similar contexts—electricity is common for other saws, hydraulic pressure is often associated with tools like cutters and spreaders, and manual labor is related to hand-held devices—compressed air is specifically advantageous for the whizzer saw. This is due to its lightweight design and ease of maneuverability, making it ideal for extrication tasks where quick and effective cutting is necessary.
