The primary function of a whizzer saw in vehicle extrication is to cut through case-hardened locks and steel up to 3/4 inches thick. This type of saw is specifically designed for cutting tough materials, making it ideal for situations where extrication requires penetrating steel components, such as in vehicles that are heavily reinforced or locked. The whizzer saw uses a diamond blade or similar cutting tool that can handle the hardness of these materials effectively.

In the context of vehicle extrication, being able to cut through locks and heavy steel is crucial for accessing trapped victims or separating vehicle components. This capability enables rescuers to quickly and efficiently overcome obstacles that would impede their rescue efforts.

The other options do not align with the primary function of a whizzer saw. Providing electrical power to tools relates more to power supply equipment than to a cutting tool. Stabilizing the vehicle is an important aspect of extrication, but it is not the role of the whizzer saw; this task is typically performed by props or stabilization systems. Lastly, tightening and securing other equipment is a function more related to fastening tools rather than the cutting capabilities that the whizzer saw provides.
