DeWalt DW3770-5 3 14 TPI T-Shank Cobalt Alloy Steel Jig Saw Blade, 5 Pack

Using the DeWalt DW3770-5 jigsaw blades is a breeze. First, make sure your jigsaw is turned off and unplugged. Then, insert the T-shank blade into the blade holder of your Bosch or DEWALT jigsaw and secure it tightly. When you're ready to cut, turn on the jigsaw and guide it steadily along your cutting line. The precision - ground teeth will give you smooth and clean cuts, and the deep gullets will help clear away the material quickly. As for maintenance, after each use, wipe the blades clean with a dry cloth to remove any debris. Store the blades in a dry place to prevent rusting. Avoid using the blades on materials they're not designed for, as this can damage the teeth and reduce the blade's lifespan.
