Diablo DOU125BF3 1-1/4″ Universal Fit Bi-Metal Oscillating Blades for Metal 3-Pack
Cut through embedded framing nails, copper pipe, screws, and metal conduit without destroying your blade. The Diablo® DOU125BF3 1-1/4" Universal Fit Bi-Metal Oscillating Multi-Tool Blades are engineered to deliver up to 5x longer life than standard bi-metal blades in medium-duty metal and nail-embedded wood applications.
Featuring high-performance bi-metal construction with an optimized tooth geometry, these plunge-cutting blades deliver faster, cooler cuts with minimal tooth strip-out. Diablo’s innovative Universal Interface System fits virtually all standard non-Starlock oscillating multi-tools straight out of the box—no adaptors required. The plunge-cut profile makes clean flush cuts, notched openings, and subfloor clearance around existing metal lines effortless and controlled.
- Up to 5x Extended Life: Premium bi-metal tooth construction withstands high friction, heat, and hard fasteners without premature tooth failure.
- Universal Fit Adapter-Free Design: Fits multi-tools from Milwaukee, DeWalt, Makita, Bosch, Rockwell, Ridgid, Porter-Cable, and more (non-Starlock).
- Deep Plunge Cut Reach: 1-1/4" cutting width and 1-1/2" cutting depth are sized perfectly for flush-cutting plumbing pipes, conduit, and framing fasteners.
- Aggressive, Clean Slicing: Specialized wavy tooth profile channels swarf out quickly to reduce vibration and prevent kickout.
- Jobsite Multipack Value: Convenient 3-pack keeps fresh cutting edges on hand across multi-room renovations and mechanical rough-ins.

Frequently Asked Questions
Will these blades fit my oscillating multi-tool brand?
Yes. The Diablo Universal Fit interface is engineered to work directly out of the box without adapters on nearly all standard oscillating multi-tools, including DeWalt, Milwaukee, Makita, Ridgid, Bosch (OIS models), Rockwell, and Porter-Cable. Note: They do not fit Starlock-only quick-change interfaces.
What materials can the Diablo DOU125BF3 cut?
These bi-metal blades are optimized for cutting non-hardened metals such as framing nails, deck screws, copper tubing, electrical conduit (EMT), thin sheet metal, and nail-embedded lumber or drywall track.
Can this blade cut hardened structural bolts or stainless steel?
No. While bi-metal easily tackles construction nails, soft bolts, and copper, extremely hard fasteners like grade 8 bolts, rebar, or thick stainless steel require Diablo's Carbide Extreme Metal oscillating blades (such as the DDU125CF series) for optimal lifespan.
How does this blade achieve up to 5x longer life than standard blades?
Diablo incorporates high-density bi-metal alloy teeth with an engineered heat-treatment process and a wavy kerf design that rapidly clears heat and debris, preventing thermal breakdown and tooth strip-out during continuous metal plunges.
