BU424 5 Metal Cutting Jigsaw Blades Pack of STRBU4245

They feature a unified shank for maximum grip and stability, a constant 24 TPI pitch, and a cutting thickness of 1.6–3.2 mm. The blades use a solid-state diffusion bonding process to achieve 170% more weld contact area, resulting in exceptionally strong teeth and improved durability. This design, along with multiple cutting edges and split chip, helps deliver faster, cleaner cuts and typically lasts about 25% longer than competing products, providing a lower cost per cut over time.
