The DEWALT DWA4280 2-1/2 in Bi-Metal Wood with Nails Oscillating Blade is a general-purpose blade built for the everyday cutting jobs on a job site or in your garage. Its bi-metal design handles wood that is hiding nails, screws, or staples without cooking the blade, so it lasts noticeably longer than ordinary carbon-steel blades. The universal fitment mounts directly on most major oscillating multi-tools, making it the go-to blade when you need to trim a door, plunge cut into drywall, or flush cut a nail-embedded board.
DEWALT DWA4280 Bi-Metal Oscillating Blade for Tough Cutoffs
Because this is a 2-1/2 inch blade, it gives you a good balance between reach and maneuverability. Use it for plunge cuts, flush cuts against door jambs, metal-embedded wood, and general remodeling work. The universal mount eliminates the guesswork for contractors and DIYers who own more than one oscillating tool brand.
Blade Selection and Best Use
Bi-metal construction: resists wear and heat when cutting nails and screws along with wood.
Universal fitment: works with most oscillating tools using standard mounting systems.
2-1/2 in length: compact enough for tight spots, large enough for clean cuts.
Whether you are a weekend remodeler or a professional finish carpenter, this is a solid choice for demolition and trim work. Store the blade in a dry place and replace it when the teeth lose their bite.

Product Details
Why the Right Oscillating Blade Matters
When you are cutting a board with an embedded nail, a standard blade can lose teeth in seconds. The DEWALT DWA4280 uses a bi-metal edge that keeps cutting through the nail and the surrounding wood, which means fewer blade changes and less downtime.
Matching the Blade to Your Task
Short, general-purpose cuts: the 2-1/2 in blade is easy to control for small trim and detail work.
Demolition and remodeling: bi-metal teeth stand up to hidden fasteners, reducing the risk of grabbing.
Multi-tool flexibility: universal fitment makes it simple to move between tools on the same job.
Keep a spare DWA4280 in your toolbox, especially during renovations where you never know what is behind the wood.
Frequently Asked Questions
Will the DEWALT DWA4280 fit my oscillating tool?
Yes. This blade features universal fitment and is designed to mount on most major oscillating multi-tool brands. Always check the tool's mounting system before use.
Can I use this blade to cut through nails?
The bi-metal construction is intended to handle wood embedded with nails and screws during normal cutting. Do not use it to cut heavy metalwork; use a dedicated metal-cutting blade for that.
How do I know when to replace the blade?
When the teeth become dull, the blade starts burning around the cut, or cutting speed drops noticeably, it is time for a new blade.
