What type of material is a pneumatic chisel especially good at cutting?

A pneumatic chisel is particularly effective at cutting through medium to heavy-gauge sheet metal due to its ability to deliver rapid, powerful strikes. This tool utilizes compressed air to drive a chisel tip against the material, making it well-suited for penetrating tough surfaces like metal. The high-speed impact allows for quick and efficient cutting, enabling the technician to create openings or free trapped victims in vehicular rescue situations.

In contrast, the other materials listed do not match the intended use of a pneumatic chisel. Plastic may be cut more easily with other tools designed for softer materials, wood can be better addressed with saws, and glass requires careful handling and specific tools to avoid shattering. Thus, the superiority of a pneumatic chisel in handling medium to heavy-gauge sheet metal makes it the clear choice for this type of task.
