The Festool 203336 Vecturo Starlock Plus Universal Saw Blade USB 78/42/Bi, 5-Pack is a universal oscillating multi-tool saw blade set built for plunge cutting and general-purpose cutting tasks. This is a universal saw blade designed for plunge cuts with an oscillating multi-tool. Model Number: 203336. If you use a Vecturo or another Starlock Plus compatible oscillating tool and want one blade style that handles a wide range of work, this is the kind of accessory that earns its place in the case.

What makes this blade useful is the combination of size and material. The blade measures 78 mm long by 42 mm wide, which gives it more reach than a short trim blade and enough width to stay useful for controlled, straight plunge work. On the job, that means better access when you need to cut into installed material, open up a section cleanly, or make controlled entry cuts where a larger saw would be awkward.

The high-grade bimetal construction matters because this is the blade style many users leave on the tool for mixed work. Bimetal gives you a tougher, more durable blade body for universal use, especially when the cut is not perfectly predictable. If you move between different materials or need one blade that can handle regular site use without feeling disposable, this is the safer bet than a more specialized blade that only shines in one narrow application.

Festool lists this blade as ideal for plunge cuts, and the extra-long profile backs that up. A longer oscillating blade helps when you need to reach deeper into a cut without crowding the nose of the tool against the work surface. That can make a real difference in cabinetry, trim adjustment, remodeling punch-list work, and controlled cut-ins where access is limited and accuracy matters.

On the interface side, this blade uses the Starlock Plus performance class. That gives it compatibility with all brands of oscillating multi-tools that use a Starlock chuck, and Festool also lists it as suitable for the OSC 18. That compatibility is a big part of the value here. You are not buying a niche blade for one unusual mount. You are buying a blade that fits into a widely used accessory system and works across a broad range of multi-tool setups that use the same connection style.

Because this is sold as a 5-pack, it makes sense for users who burn through accessories in regular work rather than occasional weekend use. Contractors, remodelers, carpenters, installers, and serious DIY users will all appreciate that this pack gives them multiple identical blades ready to go. If your work involves plunge cutting, detail access, or general oscillating multi-tool tasks and you prefer durable accessories from the Festool system, this blade pack is the straightforward buy.
