What type of blade should be used with a jigsaw for cutting metal?

The appropriate blade to use with a jigsaw for cutting metal is a metal-cutting jigsaw blade. These blades are specifically designed with finer teeth and are made from high-speed steel or bi-metal materials, which allow them to efficiently cut through various types of metal without becoming damaged or dull too quickly. The tooth configuration and material of the metal-cutting blade enable smoother cuts and better control, which are crucial when working with harder materials.

Using a blade designed for wood or plastic cutting would not be effective, as these materials require different cutting qualities, and such blades would wear out rapidly or deliver poor results when used on metal. A diamond blade is typically used for cutting harder materials like tile or concrete rather than metal, making it unsuitable for this task. Therefore, the metal-cutting jigsaw blade is the best option for this specific application.
