The Festool 204410 Vecturo Starlock Plus Segment Saw Blade SSB 32 is a segment saw blade made for oscillating multi-tools. This is a segment saw blade designed for removing window putty and caulking. Model Number 204410. If you do window repair, remodeling, or detail removal work where control matters more than brute force, this accessory makes a lot of sense.

The big story here is the blade format. A 1-1/4" (32 mm) wide segmented cutting edge gives you a controlled sweep along edges and seams, which is exactly what you want when you are working around glazing lines, old sealant, or brittle filler that needs to come out without beating up the surrounding surface. That shape also helps when you need to stay flat to the work instead of digging in like a plunge blade can.

Festool builds this blade from high-grade bimetal, which matters because putty and cured caulk removal is hard on accessories. You need a blade that can take repeated contact, vibration, and stubborn material without giving up right away. The straight blade shape keeps the cut path predictable, which is useful for detail work where a sloppy edge turns into extra cleanup.

On the connection side, this blade uses the Starlock interface and is listed with a Starlock Max performance class. Festool also lists it as suitable for the OSC 18, so it is clearly aimed at the Vecturo oscillating tool platform. For buyers already in that system, this is the purpose-built accessory for removal work that calls for control more than aggressive demolition.

Just as important, Festool specifically notes that this blade is not suitable for sawing metal, including glazing sprigs. That is worth paying attention to. This is not a general-use demolition blade. It is a task-focused oscillating multi-tool blade for sealant and putty removal, and that is exactly where it earns its keep.

Who should buy it? Pros doing window restoration, punch-list repair, renovation, and careful teardown work will get the most out of it. Serious DIY users tackling sash repair or old caulk removal will also appreciate it, especially if they already own an OSC 18 and want the right blade for a specific job instead of forcing a general-purpose accessory to do precision work.
