Need blades that can handle tough jobs and last longer than the cheap ones? This 5-pack of Milwaukee bi-metal jigsaw blades is built for pros and serious DIYers. They're 4 inches long with 6 teeth per inch (TPI), which is ideal for fast, aggressive cuts in wood, especially if you're cutting through old lumber that might have nails in it. The bi-metal construction (a combo of high-speed steel teeth and a flexible alloy steel back) means they're way more durable and last longer than standard carbon or high-speed steel blades. They have a T-shank design that fits most popular jigsaws, including Milwaukee models 6266-6, 6276-6, 6267-20, and 6267-21. The tooth geometry is designed for clean, fast cuts with less vibration. Whether you're doing remodeling, cutting plywood, or general carpentry, having a pack of these on hand saves time and frustration. They're a reliable, no-nonsense upgrade for your toolkit.
