The Festool 500251 Vecturo Depth Stop Set is an accessory set for the Festool OS 400 Vecturo oscillating multi-tool. This is a multi-tool accessory designed for controlled plunge cutting and accurate positioning in delicate finish materials and layout-sensitive cutouts. Model Number 500251. If you use an OS 400 for restoration work, outlet openings, flooring repairs, or detailed interior cuts, this add-on gives you much better control than freehand work.

What makes this set worth having is the combination of depth control and guided positioning. The depth stop lets you set a defined plunge depth for exacting cuts, which helps when you need to avoid cutting into material behind the surface or when you want repeatable depth across multiple openings. The positioning aid is there to help track a mark cleanly, so the tool starts and follows the cut where you intended instead of wandering at the start.

Festool also built this around fast setup. The depth stop, positioning aid, and blade mount without tools, which is a real advantage on site when you are moving between tasks and do not want extra downtime for adjustments. That matters even more on an oscillating multi-tool, where accessories often get swapped depending on whether you are trimming, plunging, or making a finish cut in place.

The included sliding shoe is especially useful with circular blades on even surfaces. It helps support the tool while maintaining a consistent cutting depth, which can make a visible difference when you are working on parquet, laminate, drywall, or wood cutouts that need to stay neat. Festool specifically positions this set for clean cuts, perpendicular plunge cuts, and work that follows a scribe line, so it is not just a generic attachment bundle.

Compatibility is straightforward: this set is made for the Festool OS 400 platform. That is important, because this is not a universal oscillating multi-tool guide. If you already run the Vecturo OS 400 and want more control for precision cutouts, this is the right type of accessory. If you do not have the OS 400, this is not the piece to buy.

Who should buy it? Flooring installers, remodelers, finish carpenters, restoration crews, and anyone doing clean interior cutouts with an OS 400. It is also a smart pickup for users cutting electrical box openings in drywall or wood, trimming mortise areas, or handling detail work in finished spaces where accuracy matters more than brute speed.
