These high-performance blades feature a propriety carbide blend to deliver an impressive up to 50X longer life than standard blades. The innovative curve contact edge creates a pilot for precise, clean plunge cuts with less vibration while the Black Ice (Industrial Cooling Element) coating protects the cutting edge for extreme durability in aggressive cutting applications. A tool-free quick-change interface fits Fein and other Starlock tools, also compatible with most non-Starlock multi-tools.Diablo high-performance carbide for up to 50X longer life than standard bi-metal bladesBlack Ice protects the cutting edge against wear for extreme durability and longer life
