Diablo’s universal fit bi-metal oscillating blades feature application specific designs that deliver maximum durability and longer life in drywall. These high-performance blades feature an ultra-hardened cutting edge to deliver up to 5X 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. The blade’s universal fit, adapter-free design easily attaches most tools, with the exception of Starlock tools.
