If you're cutting through tough stuff like laminate flooring, metal, hardwoods, or abrasive materials with your jigsaw, you need a blade that can keep up. This LENOX blade is the one. It's a T-shank design (fits most modern jigsaws), 4 inches long, 5/16 inches wide, and has 6 teeth per inch (TPI). The key feature is the carbide tips welded onto each tooth. Carbide is way harder than standard high-speed steel, so this blade stays sharp longer and powers through materials that would chew up a regular blade in no time. Each tooth is also precision-ground for a faster, cleaner cut. It's a single blade in the pack, but it's built for long life, so you might not need to change it as often. Just pop it into your saw when you've got a project that requires some extra muscle. It's a professional-grade blade that makes a huge difference in cutting speed and blade longevity for DIYers and pros alike. No more struggling through cuts or burning up blades. Get it done faster and cleaner.
