The Diablo DOS125BW10 1-1/4 in. Demo Demon Starlock Bi-Metal Oscillating Blades for Nail-Embedded Wood (10-Pack) is a multi-tool blade pack built for cutting wood that may contain nails. This is a bi-metal oscillating blade designed for plunge cutting and demolition work in nail-embedded wood, hardwoods, and softwoods. Model Number: DOS125BW10. It is a smart pick for remodelers, carpenters, flooring installers, punch-list crews, and serious DIY users who need blades that last longer when the material is not clean or predictable.

What matters here is durability under real jobsite conditions. Diablo calls out an ultra-hardened cutting edge that delivers up to 5 times longer blade life than standard bi-metal blades. On the job, that means fewer blade changes when you are cutting into old framing, trim removal zones, subfloors, or repair areas where fasteners are still buried in the wood. For anyone using an oscillating multi-tool for demolition, repair cuts, or flush cutting around existing material, that longer life is the feature that pays for itself.

The 1-1/4 inch blade width gives you a useful balance between control and coverage. It is wide enough for stable plunge cuts and cleanup work, but still compact enough for detail cutting in tighter spots. Diablo also lists up to 2 inches of cutting depth, which gives this blade enough reach for a lot of common remodeling and repair tasks without stepping up to a different accessory. If you are cutting out damaged sections, trimming back wood around a fastener, or opening up a section for patch work, that depth matters.

One of the better design details on this blade is the curve contact edge. That shape helps the blade start cleaner and track more predictably into the cut, with less vibration and chatter. In plain terms, it helps the blade settle into the material instead of skating around while you try to start a plunge. That is useful when you are working in finished spaces, doing controlled cut-ins, or trying to avoid tearing up surrounding material.

Diablo also uses its Black I.C.E. coating to protect the cutting edge against wear. The practical benefit is heat and wear resistance during repeated cuts, especially when you are bouncing between softwood, hardwood, and nail-hit sections. On oscillating tool accessories, heat is what kills edges fast, so any improvement there helps extend usable life and keeps cut quality more consistent across the pack.

For fitment, this blade is made for Starlock tools and is specifically called out for use with Fein and other Starlock models. Diablo also states compatibility with many non-Starlock oscillating multi-tools from AEG, Bosch, Festool, Makita, Metabo, Milwaukee, Ridgid, Rockwell, and more. Just as important, Diablo explicitly says these blades are not compatible with Craftsman, DeWalt, Dremel, Hart, or Porter-Cable. If you are buying blades for a mixed fleet or replacing what is already in your truck, that compatibility note is worth checking before you order.

This 10-pack makes the most sense for users who burn through blades regularly and do not want to stop mid-job because one blade got smoked by hidden nails. It is not just a general wood-cutting accessory. It is aimed at tougher fastening and demolition cuts where a standard wood blade will not last. If your oscillating tool mostly handles repair work, renovation cuts, flooring tear-out, trim removal, or plunge cuts into suspect material, this is the right kind of blade to keep on hand.
