Power saw

This is a high-speed pneumatic tool using interchangeable,reciprocating hacksaw blades (Figure3.48). It is able to cut from straight lines totight curves. Cutting can be started anywhere on a panel without the need for pilot holes. Single- or double-skinned panel assemblies can be easily cut owing to the short blade stroke. The tool can be used to cut a wide variety of materials including light- gauge steel,aluminium,reinforced glass fibre,wood and hardboard. Its fine cut is ideally suited for panel replacement where joints have to be cut and welded.
Another power saw is the rotary or circular saw (Figure 3.49).
