Diablo, 1-1/4'' oscillating blade for Nail Embedded wood. Diablo's Starlock bi-metal oscillating blades feature application specific designs that deliver maximum durability and longer life in nail-embedded wood applications. These high-performance blades feature an ultra-hardened cutting edge to deliver up to 5 times longer life than standard blades. Curve contact edge creates a pilot for precise, clean plunge cuts with less vibration. Black I.C.E. (industrial cooling element) keeps the teeth cool and build up free for fast, clean cuts. Tool free quick-change interface fits Fein and other Starlock tools, also compatible with most Non-Starlock multi-tools.
