Bi-metal oscillating multi-tool plunge blade for flush cuts, plunge cuts, and undercut work in wood, drywall, plastic, fiberglass, and nail-embedded wood. High-speed steel cutting teeth are electron-beam welded to a flexible alloy steel back so the teeth stay sharp through nails and metal trim without the blade body snapping. Black oxide finish reduces friction and gumming when cutting resinous wood, drywall paper, or PVC. Universal three-tab mount fits most older OIS-pattern oscillating multi-tools (Bosch pre-Starlock, DeWalt, Milwaukee, Makita, Ridgid, Ryobi, Porter-Cable, Rockwell, Genesis) and many Starlock holders with an adapter.

• Bi-metal construction: HSS teeth welded to flexible alloy steel back
• Black oxide finish resists gumming and corrosion
• Universal 3-tab mount (older OIS pattern); adapter required for Starlock-only tools
• Fully ground, heat-treated teeth for long life in mixed materials
• Side cutting edges allow plunge cuts and flush cuts against vertical surfaces
• Cuts wood, drywall, plastic, fiberglass, and embedded nails up to 16d common

Selection Tip: 2-1/2" (65 mm) is the maximum-width plunge blade -- deck board replacement (cut both ends of a damaged board mid-span without disturbing joists), long straight cuts in subflooring, large-format drywall patches, and rough-in openings for floor registers. Wider blade means more teeth in the cut for a smoother finish but also higher gearbox load -- ease into the cut at medium oscillation speed.

Use Tip: Let the tool oscillate at speed before contacting the workpiece. Use light pressure and let the teeth feed -- pushing hard heats the bi-metal weld and shortens blade life. For long straight cuts, work the blade in a slight rocking motion to clear chips; for plunge cuts, tilt the blade to start a corner rather than dropping flat into the surface.

Care Tip: A wire brush takes drywall and pitch off the teeth between cuts. Replace when teeth round over or the blade discolors blue near the tip from heat -- a dull bi-metal blade loads the oscillator gearbox and can burn out the motor on extended runs. Store dry; the black oxide is thin and will rust under humid conditions.

Note: Not rated for hardened steel screws, masonry, or cast iron -- step up to carbide-grit or diamond-grit oscillating blades for those materials. Wear ANSI-rated eye protection; oscillating blades throw fine chips at high frequency.
