An 87mm bi-metal radial blade for oscillating multi tools. Cuts wood, copper and aluminium pipe, sheet metal, plastics and laminated boards. Features a flat side for flush cutting against surfaces. Quick release fitment compatible with most major multi tool brands.
The 87mm bi-metal multi tool radial blade is one of those accessories that earns its keep fast. Whether you’re cutting copper pipe tucked behind a wall, trimming skirting in place, or working through sheet metal on a fit-out job, this blade handles the kind of mixed-material cutting that trips up single-spec blades. The bi-metal construction combines a tough HSC body with an HSS cutting edge, giving you the flexibility to move between wood, metal and plastics without swapping blades every five minutes.
Radial blades are shaped differently to standard segment or plunge-cut blades. The flat side sits flush against a flat work surface, which makes them the go-to choice when you need to cut close to a floor, wall or adjacent surface without gouging into it. Fitting skirting boards, undercutting door frames, trimming plastic profiles flush — this is where the 87mm radial format really comes into its own.
Where This Bi-Metal Radial Blade Gets Used
On site, this blade covers a lot of ground. Joiners use it for undercutting architraves and door linings before laying flooring. Plumbers reach for it when copper or aluminium pipe needs cutting in a tight spot where a pipe cutter simply won’t fit. It handles sheet metal, plastic conduit and profiles cleanly, and it’s equally at home cutting veneered or laminated boards where a standard wood blade might chip or snag the surface finish. Parquet and engineered flooring repairs, partition wall work, and general second-fix trimming are all well within its scope.
Fitment Compatibility
Quick release fitment means it drops straight onto the tool without needing a hex key or separate collar. It’s compatible with AEG, Black and Decker, Bosch, Craftsman, DeWalt, Einhell, Fein MultiMaster, MacAllister, Makita, Mastercraft, Milwaukee, Rigid, Rockwell, Skil, Stanley and most other oscillating multi-function tools. If your machine takes a standard universal fit blade, this will almost certainly work on it. Worth keeping a couple in the bag given the price and the range of cuts it covers.
At under five pounds a blade, the 87mm bi-metal radial is genuinely good value for what it does. It won’t last forever on heavy steel — nothing will — but for mixed site work across wood, non-ferrous metals and plastics, it performs well above its price point.
Pro Tip: When cutting flush against a floor or wall, let the tool do the work at a steady pace rather than pushing hard. Forcing the blade into the cut generates excess heat and will dull the HSS edge far quicker than a controlled, consistent stroke.
This blade is used across a wide range of trades and site situations. Joiners rely on radial blades for undercutting door frames and architraves before flooring goes down. Plumbers use them to cut copper and aluminium pipe in confined spaces. Electricians and first fixers find them useful for trimming plastic conduit and profiles. The bi-metal construction also makes it a practical choice for cutting laminated or veneered boards in flooring and partition work without risking surface breakout.

Not suitable for: Not recommended for cutting hardened steel, stainless steel or masonry. For heavy or continuous steel cutting, a dedicated metal-specific blade will hold its edge significantly longer.
Fit the blade to your oscillating multi tool using the quick release mechanism — no tools needed on most machines. For flush cuts against a floor or wall, position the flat side of the blade against the surface before starting the tool, then bring it up to speed before making contact with the workpiece. Keep the tool moving at a steady pace. Let the blade cut; pressing hard shortens its life and can cause the blade to wander off line.
When cutting pipe in confined spaces, start at a low oscillation speed if your tool allows it. This gives better control and reduces the chance of the blade skating across a smooth metal surface on the initial entry. On laminated or veneered boards, a few slow passes to score the surface first will keep the finish clean.
Ensure your multi tool is unplugged or the battery is removed before fitting the blade
Attach the 87mm radial blade using the quick release fitment on your tool
For flush cutting, position the flat face of the blade against the adjacent surface before switching on
Start the tool and allow it to reach full speed before applying cutting pressure
Move the tool steadily along the cut line without forcing it
On laminated or veneered surfaces, score lightly on the first pass to prevent breakout
Allow the blade to cool between extended cuts, particularly when working through metal
Will this blade fit my Bosch or DeWalt multi tool?
Yes. The quick release fitment on this blade is compatible with Bosch, DeWalt, Makita, Milwaukee, Fein MultiMaster and most other major oscillating multi tool brands. If your machine accepts standard universal-fit blades, this will work on it.
Can this blade cut through copper pipe?
Yes, it is suitable for cutting copper and aluminium pipe. The bi-metal construction with an HSS cutting edge handles non-ferrous metals well, making it a practical choice when you need to cut pipe in a spot where a standard pipe cutter cannot reach.
The blade body is manufactured from HSC (High Speed Carbon) steel, with an HSS (High Speed Steel) cutting edge bonded to it — a standard bi-metal construction that balances flexibility in the body with hardness at the cutting teeth. At 87mm, the radial format provides a wide cutting arc suited to flush work and surface-parallel cuts. Quick release fitment uses the universal OIS-compatible interface accepted by the majority of current oscillating multi tool platforms.
