Festool USB 50/35/Bi/OSC/5 Universal Bimetal Saw Blades

At a Glance: Robust 50 x 35 mm Starlock universal saw blades for the Festool OSC 18 oscillating multi-tool. High-grade bimetal construction and universal toothing make these blades ideal for plunge cuts and versatile cutting in wood, coated or painted wood, composite materials, GRP, plasterboard, non-ferrous metals and plastics. Durable enough to cope with occasional nails embedded in wood. Supplied in a pack of 5.

The Festool USB 50/35/Bi/OSC/5 is a professional universal oscillating saw blade designed for users who regularly move between different materials without wanting to change blades for every individual task. Manufactured from high-grade bimetal and equipped with universal toothing, the blade combines excellent cutting speed, clean cutting performance and long service life. Its 50 mm length and 35 mm width make it particularly well suited to controlled plunge cuts, cut-outs and detailed installation work. Festool specifically rates the blade for wood, coated wood, painted wood, composite materials, glass-fibre-reinforced plastic (GRP), plasterboard, non-ferrous metals and plastics. The tough bimetal construction also makes it resistant to occasional nails encountered in timber. A Starlock mounting interface provides secure power transfer and allows fast, tool-free blade changes on the Festool OSC 18. Five blades are supplied in the pack for demanding professional workshop and site use.

The robust all-rounder for mixed-material work

The USB 50/35/Bi/OSC is designed as a true universal blade rather than a material-specific specialist. Its bimetal construction and universal tooth geometry make it especially useful during renovation and installation work where the material can change from timber to plasterboard, plastic, composite material or non-ferrous metal within the same job.

Extra Information

What does USB mean? USB identifies Festool&s Universal Saw Blade family for oscillating multi-tools.
What does 50/35 mean? The blade has a nominal length of 50 mm and width of 35 mm.
What does Bi mean? Bi identifies the blade&s bimetal construction, chosen for improved durability and versatility compared with a blade intended only for ordinary wood.
What does OSC mean? OSC identifies the Festool oscillating-tool application and this blade is specifically listed for the OSC 18.
What does /5 mean? The package contains five blades.
What is Starlock? Starlock is the blade mounting interface used to connect the accessory securely to a compatible oscillating multi-tool while providing efficient transfer of the machine&s oscillating movement.
What does offset blade shape mean? The blade body is formed so the cutting section sits in a practical working position relative to the tool, helping with flush, plunge and installation cuts.
Can it cut nails? Festool specifically describes the blade as robust even against nails found in wood. It is therefore useful for renovation work where occasional hidden nails may be encountered.
Is it a dedicated metal blade? No. It is a universal bimetal blade. Festool specifically lists non-ferrous metals among its suitable materials, but the blade is designed as a versatile all-rounder rather than a dedicated heavy-metal-cutting accessory.
Is it suitable for plunge cutting? Yes. Festool specifically identifies plunge cuts as one of the blade&s key applications.

What is a bimetal oscillating saw blade?

A bimetal blade combines materials selected for different mechanical properties so the cutting section can provide good wear resistance while the blade remains tough enough to withstand demanding oscillating movement. This construction is particularly valuable in renovation work where timber may contain an unexpected nail or where several different materials need to be cut with the same blade.

Why universal toothing?

A specialist wood blade can be extremely fast in clean timber, while a dedicated material-specific blade may excel in one particular application. Universal toothing instead prioritises versatility, allowing the USB 50/35/Bi/OSC to deliver useful cutting performance across wood, coated materials, composites, GRP, plasterboard, plastics and non-ferrous metals.

Why oscillating tools are so effective for plunge cuts

An oscillating blade moves through a very small angle rather than rotating continuously. This allows the cutting edge to be placed directly onto a marked area and carefully plunged into suitable material, making the tool especially useful for cut-outs, recesses and modification work where a conventional circular or reciprocating saw may not have sufficient access.

Pro Tips

Mark both sides of a required cut-out where possible so the blade can be kept accurately within the intended area.
Allow the oscillating action to do the cutting; excessive forward pressure can increase heat and shorten blade life.
Use a gentle rocking movement during longer cuts to keep more of the tooth line working efficiently.
When plunge cutting, enter the material gradually rather than forcing the full width of the blade into the surface immediately.
Reduce pressure when cutting plastics to limit excessive heat build-up or melting.
Use suitable cutting speed for the material rather than operating automatically at maximum speed.
When working near hidden fasteners, take advantage of the bimetal construction but avoid deliberately cutting heavy steel components for which the blade is not specified.
Keep the Starlock mounting surfaces clean so the blade seats correctly and power transfer remains efficient.
Rotate or reposition the tool rather than twisting the blade sideways inside a deep cut.
Replace a blade when its teeth become badly worn or damaged; forcing a blunt blade increases heat and reduces control.
Use dust extraction where practical when cutting plasterboard, composites or dusty wood-based materials.
Make a test cut in an offcut when working with unfamiliar plastics, composites or coated materials.

How to Use

Confirm that the material is suitable for the universal bimetal blade.
Switch off the OSC 18 and remove the battery before fitting or changing the blade.
Inspect the Starlock mounting area and remove any accumulated dust or debris.
Position the USB 50/35/Bi/OSC blade at the most useful working angle for the planned cut.
Secure the blade using the OSC 18&s tool-free mounting system according to the machine instructions.
Confirm that the blade is fully seated and locked before reinstalling the battery.
Secure loose or movable workpieces before cutting.
Mark the intended cut clearly.
Select a suitable oscillation speed for the material.
Start the machine before bringing the cutting teeth into controlled contact with the workpiece.
For a plunge cut, introduce the blade gradually while maintaining firm control of the machine.
Guide the tool using moderate pressure and allow the teeth to cut without excessive force.
Where appropriate, use a slight rocking action to distribute wear across the cutting edge.
Withdraw the blade carefully once the cut is complete.
Allow the tool and blade to stop completely before placing the machine down or changing accessories.

Safety

Wear suitable eye protection whenever operating an oscillating multi-tool.
Use hearing protection where required by the machine, material and working environment.
Use suitable respiratory protection and dust extraction when cutting dusty materials such as plasterboard and wood-based panels.
Remove the battery from the OSC 18 before installing, repositioning or removing the blade.
Make sure the Starlock blade is fully seated and securely locked before starting the tool.
Inspect the blade before use and do not use a blade that is cracked, badly bent or has severely damaged teeth.
Secure loose workpieces before cutting.
Check the cutting area for concealed electrical wiring, plumbing and other hazards before making a plunge cut.
Use an appropriate oscillation speed for the workpiece material.
Do not apply excessive sideways force to the blade, particularly during deep plunge cuts.
Be aware that the blade can become hot during prolonged cutting; allow it to cool before handling.
Take additional precautions when cutting painted or coated material if the composition of the coating is unknown.
Although the blade can cope with occasional nails in wood, do not use it as a substitute for a dedicated blade where continuous heavy metal cutting is required.
Follow the Festool OSC 18 operating and safety instructions at all times.
