For wood, choose blades with a high tooth count (10-18 TPI) for smooth cuts and 4-8 TPI for rough cuts or demolition. Use a wood-specific blade; the teeth are designed for cleaner, more controlled cuts in the grain.
Metal cutting demands blades with fewer, larger teeth (3-6 TPI). High-speed steel (HSS) blades are ideal for ferrous metals like steel and iron, while bi-metal blades offer a balance of durability and versatility for a wider range of metals, including non-ferrous options like aluminum.
Cutting plastic requires a blade with a finer tooth pitch than wood, but coarser than metal (8-14 TPI). A fine-tooth blade minimizes chipping and melting. The correct blade type prevents damage to the material and blade itself.
For masonry, select a carbide-tipped blade. These blades are specifically designed to withstand the abrasive nature of concrete, brick, and other masonry materials. The carbide teeth provide superior wear resistance and longer blade life.
Always remember safety precautions: wear appropriate safety glasses and hearing protection. Choose blades that fit your reciprocating saw correctly. Improper blade selection can result in poor cuts, blade breakage, and potential injury.
