Product description
Festool USB 78/32/Bi/OSC/5 Universal Bimetal Saw Blades
At a Glance: Extra-long 78 x 32 mm Starlock Max universal saw blades for the Festool OSC 18 oscillating multi-tool. Manufactured from high-grade bimetal with universal toothing for fast, clean and durable cutting across wood, coated and painted wood, composites, GRP, plasterboard, non-ferrous metals and plastics. The extended 78 mm blade length provides excellent reach for deeper plunge cuts. Supplied in a pack of 5.
The Festool USB 78/32/Bi/OSC/5 is a robust universal oscillating saw blade designed for demanding installation, renovation and repair work where a broad range of materials may need to be cut with the same accessory. Its high-grade bimetal construction combines toughness with excellent wear resistance, while Festool's universal tooth geometry provides a strong balance of cutting speed, cutting quality and service life. At 78 mm long and 32 mm wide, this version provides substantially greater plunge-cutting reach than shorter universal blades while retaining a relatively narrow profile for accurate, controlled cut-outs. The offset blade shape also assists chip removal during deep cutting. Festool specifies the USB 78/32/Bi/OSC for wood, coated wood, painted wood, composite materials, glass-fibre-reinforced plastics, plasterboard, non-ferrous metals and plastics. The tough bimetal construction can also cope with occasional nails encountered in timber. Its Starlock Max interface provides secure power transfer on the Festool OSC 18 and supports fast, tool-free blade changes.
The defining advantage of the USB 78/32/Bi/OSC is its 78 mm blade length. This provides additional reach when cutting deeper into suitable materials, making it especially useful for plunge cuts, deeper recesses and installation work where a conventional 50 mm oscillating blade cannot reach far enough.

Extra Info
Extra Information
- What does USB mean? USB identifies Festool's Universal Saw Blade family for oscillating multi-tools.
- What does 78/32 mean? The blade measures 78 mm long and 32 mm wide.
- What does Bi mean? Bi identifies the blade's bimetal construction, selected for excellent toughness, durability and mixed-material capability.
- What does OSC mean? OSC identifies the Festool oscillating-tool application. This blade is specifically specified for the OSC 18.
- What does /5 mean? The package contains five saw blades.
- What is Starlock Max? Starlock Max is the blade's high-performance mounting class. It provides a secure connection to compatible oscillating tools and transfers the machine's oscillating movement efficiently to the accessory.
- Why is this blade described as extra-long? At 78 mm, it provides substantially more reach than Festool's 50 mm universal blades and is therefore particularly useful for deeper plunge cuts.
- Why is the blade offset? The offset profile allows practical positioning of the cutting edge and assists removal of chips during deep cuts.
- Can it cut nails? Festool specifically states that the universal bimetal blade is robust even against nails found in wood, making it useful during renovation and dismantling work.
- Can it cut metal? Festool specifically approves the blade for non-ferrous metals. It is a universal blade rather than a specialist blade intended for continuous heavy steel cutting.
- Is it suitable for plunge cuts? Yes. Plunge cutting is one of the primary applications for the USB 78/32/Bi/OSC, with the extra blade length providing particularly good depth capability.
Shorter oscillating blades are excellent for shallow recesses and compact work, but their useful cutting depth is naturally limited by blade length. The 78 mm USB extends considerably farther from the Starlock interface, making it the better option when deeper plunge cuts or longer reach are required.
Renovation work often involves material combinations that are difficult to see before cutting. A timber component may be painted, laminated, reinforced or contain a hidden nail. Bimetal construction gives the USB blade considerably greater toughness for these mixed applications than a specialist HCS wood blade.
The tooth geometry is designed as a compromise between highly specialised cutting profiles. Rather than being optimised only for clean timber or only for metal, it provides useful cutting speed, quality and durability across the broad material range encountered during installation and renovation work.
An oscillating blade moves rapidly through a very small angular range rather than rotating continuously. This allows the blade to be placed directly onto a marked area and progressively entered into suitable material, making the OSC 18 especially useful for cut-outs and recesses where access with a conventional saw is difficult.
Pro Tips
- Choose the 78 mm blade when the required plunge depth exceeds the practical reach of a shorter 50 mm blade.
- Mark the full outline of a cut-out before beginning so the extra blade length can be controlled accurately.
- For deep plunge cuts, enter the material gradually rather than forcing the complete cutting edge into the surface at once.
- Use a gentle rocking movement where appropriate to improve chip clearance and distribute wear across the teeth.
- Allow the blade to cut at its natural rate; excessive pressure creates heat and can shorten blade life.
- Reduce machine speed and feed pressure when processing plastics to minimise melting.
- When encountering an occasional nail in timber, maintain controlled pressure rather than forcing the blade through the fastener.
- Use a positioning aid where the application requires a particularly controlled deep plunge cut.
- Keep the Starlock Max mounting surfaces clean so the blade seats completely and transfers power efficiently.
- Avoid twisting the long blade sideways inside a deep cut, as the additional leverage can place unnecessary stress on the accessory.
- Replace the blade when cutting performance deteriorates significantly rather than compensating with additional machine pressure.
- Make a test cut when working with unfamiliar composite or plastic materials.
How to Use
- Confirm that the workpiece material is suitable for the universal bimetal blade.
- Remove the battery from the Festool OSC 18 before fitting or changing the accessory.
- Inspect the Starlock Max mounting interface and remove any compacted dust or debris.
- Position the USB 78/32/Bi/OSC blade at the most suitable angle for the planned cut.
- Secure the blade using the OSC 18's tool-free accessory mounting system.
- Confirm that the blade is fully seated and securely locked.
- Secure loose or movable workpieces before cutting.
- Mark the intended cutting position clearly.
- Check behind the cutting area for cables, plumbing or other hazards before making a deep plunge cut.
- Reinstall the battery and select an appropriate oscillation speed for the material.
- Start the OSC 18 before bringing the blade into controlled contact with the workpiece.
- For plunge cuts, enter the material progressively while keeping firm control of the tool.
- Guide the blade using moderate pressure and allow the universal teeth to remove material.
- Use a slight rocking action where helpful for chip clearance.
- Avoid applying excessive sideways force to the long blade.
- Withdraw the blade carefully once the required cut depth or cut-out has been completed.
- Allow the blade to stop completely before setting the machine down or changing accessories.
Safety
Safety
- Wear suitable eye protection whenever operating an oscillating multi-tool.
- Use hearing protection where required by the machine, material and working environment.
- Use appropriate dust extraction and respiratory protection when cutting plasterboard, composites and dust-producing wood materials.
- Remove the battery from the OSC 18 before fitting, repositioning or removing the blade.
- Make sure the Starlock Max blade is fully seated and securely locked before starting the machine.
- Inspect the blade before use and do not use it if cracked, badly bent or severely damaged.
- Secure loose or movable workpieces before cutting.
- Check behind the cutting area for concealed electrical cables, plumbing and other hazards before making deep plunge cuts.
- Use an oscillation speed appropriate to the material being cut.
- Do not apply excessive sideways force to the extra-long blade.
- Although the blade can cope with occasional nails in wood, do not use it as a substitute for a dedicated metal blade where continuous heavy metal cutting is required.
- Use additional care when cutting painted or coated material if the coating composition is unknown.
- The blade can become hot during prolonged cutting; allow it to cool before handling.
- Keep hands away from the cutting edge whenever the machine is energised.
- Follow the Festool OSC 18 operating and safety instructions at all times.
