DeWalt DWA41812 12 2X Premium Metal Cutting Reciprocating Blade (5 pack)

Using these DeWalt reciprocating blades is easy. Just insert the blade into your reciprocating saw following the saw's instructions. When cutting, apply steady pressure and let the blade do the work. Avoid forcing the saw through the material as this can cause the blade to overheat or break. As for maintenance, after each use, clean the blade with a dry cloth to remove any metal shavings. If the blade gets dirty, you can use a mild solvent, but make sure to dry it thoroughly. Store the blades in a dry place to prevent rusting. Replace the blade when it becomes dull or damaged for the best cutting performance.
