The Diablo Demo Demon DOU250BW10 is a 10-pack of wide-format 2-1/2" bi-metal oscillating blades built for demolition and remodeling work in nail-embedded wood. The wider blade removes material faster on big openings, and the ultra-hardened cutting edge delivers up to 5X longer life than standard bi-metal blades in the same application.

• 2-1/2" cutting width for fast material removal on deck-board replacement, large drywall patches, and door-jamb undercuts
• Bi-metal construction: HSS teeth electron-beam welded to flexible alloy back to handle nails and screws without snapping
• Ultra-hardened cutting edge for up to 5X longer life vs standard bi-metal in nail-embedded wood
• Curve Contact Edge creates a pilot for precise, clean plunge cuts with less vibration
• Black I.C.E. (Industrial Cutting Edge) coating resists heat buildup and corrosion
• Universal OIS interface fits Bosch, Milwaukee, DeWalt, Makita, Ridgid, Porter-Cable, Ryobi, and most cordless and corded multi-tools (Starlock-only tools excepted)
• 10-pack sized for full-house teardowns, multi-day remodels, and contractor crew restock

Use Tip: Start the tool before contact, apply light pressure, and rock the blade slightly to clear chips. The wider blade benefits from a longer rock to clear the kerf -- don't push straight through. For plunge starts, tilt the corner of the blade into the work and pivot it flat once the cut opens.

Care Tip: Wire-brush teeth between cuts to clear pitch and nail debris. Retire each blade when the cutting edge turns blue or the curve flattens out -- continuing past that point loads the tool's gearbox.

Note: HSS bi-metal is not rated for masonry, cast iron, or hardened screws. Step up to carbide-grit or diamond-grit blades for those materials.
