The DIABLO DOU125LCGP is a Demo Demon oscillating blade engineered for aggressive cutting through nail-embedded wood, clean wood, metal, and plastic. This multi-material blade is built for demolition and remodel work where mixed substrates and hidden fasteners are unavoidable. It mounts to standard oscillating multi-tools and is sold individually, making it a direct replacement or supplemental addition to a working blade kit. The DOU125LCGP is the go-to blade when the material is unknown or the workpiece is likely to contain embedded fasteners that would destroy a standard wood-only blade.
This blade is suited for residential and light commercial demolition, remodeling, and rough carpentry applications. Typical use cases include cutting through subfloor assemblies with nails, trimming door jambs with mixed materials, and flush-cutting in tight spaces where a reciprocating saw cannot fit. It is designed for trade professionals including carpenters, remodelers, demolition contractors, and general construction crews who rely on oscillating tools for precision teardown and fit-out work.
Designed as an OEM-style replacement and aftermarket option for standard oscillating multi-tool systems accepting universal-fit accessory blades.
Oscillating blade changes should be performed with the tool unplugged or the battery removed before swapping accessories. Most oscillating multi-tools require either a hex key or a tool-free lever mechanism to secure the blade clamp - confirm the clamping method on the specific tool before installation. Ensure the blade is fully seated and the clamp is firmly tightened before resuming work. When cutting near electrical wiring or plumbing, follow applicable safety protocols and de-energize circuits in accordance with OSHA and NEC guidelines.
