Jigsaw blades are specialized cutting tools designed for use with a jigsaw, a power saw that moves the blade up and down to cut various materials. These blades come in different shapes, sizes, and materials, allowing them to cut through wood, metal, plastic, and more. The type of blade chosen depends on the specific project and the material being cut. The blades are typically categorized by their tooth design, which affects the cut's smoothness and speed. Common types include wood blades, metal blades, and bi-metal blades, each tailored for specific applications. Proper selection of a jigsaw blade ensures efficient and accurate cutting results.
