Festool OS-AH Set Positioning Aid

At a Glance: Precision plunge-cutting guide for the Festool OS 400 VECTURO, featuring tool-free mounting, accurate alignment on scribe marks and a maximum guided plunge depth of 60mm.

Position the Festool OS 400 VECTURO accurately and produce controlled, perpendicular plunge cuts with the Festool OS-AH Set Positioning Aid. The guide base allows the oscillating saw blade to be aligned precisely with a marked cutting line before it enters the workpiece, making it particularly useful for creating cut-outs in delicate or visible surfaces. Its magnetic blade catch helps stabilise the blade during positioning and cutting, while the rubberised contact pad provides a secure grip without unnecessarily marking the workpiece. Tool-free mounting and adjustable positioning reduce set-up time, allowing accurate plunge cuts up to 60mm deep with compatible blades.

Accurate plunge cuts directly on the marked line

The OS-AH Set supports the VECTURO and guides the saw blade perpendicular to the workpiece. This improves control when beginning a plunge cut and helps produce accurate openings in panels, fitted components and sensitive finished surfaces.

Product Highlights

  • Precise alignment: Positions the saw blade accurately along a marked cutting line before the plunge cut begins.
  • Perpendicular plunge cutting: Guides the blade at a right angle to the workpiece for controlled, repeatable cuts.
  • Up to 60mm plunge depth: Supports deep guided cuts with a suitable compatible saw blade.
  • Magnetic blade stabilisation: Helps hold the oscillating saw blade securely in the intended position.
  • Virtually splinter-free results: Supports clean plunge cuts in suitable delicate and visible surfaces.
  • Tool-free installation: The positioning aid and compatible blades can be mounted without separate tools.
  • Adjustable positioning: Multiple angle settings allow the guide to be adapted to the application.
  • Surface protection: A rubberised contact pad improves grip while helping protect the workpiece.
  • Designed for the OS 400: Purpose-made for the Festool OS 400 VECTURO oscillating tool.

Pro Tips

  • Mark the complete cut-out clearly and confirm its dimensions before beginning the first plunge cut.
  • Select a saw blade long enough for the required depth without exceeding the 60mm capacity of the guide.
  • Check that the blade is straight, sharp and correctly seated before mounting the positioning aid.
  • Place low-tack masking tape over delicate surfaces before marking and cutting to provide additional protection.
  • Allow the magnetic catch to stabilise the blade before aligning it with the scribe mark.
  • Hold the base firmly against the workpiece throughout the plunge movement.
  • Use a steady feed rate and allow the oscillating blade to cut without excessive downward pressure.
  • Stop just short of intersecting corners when creating a cut-out, then complete the corners carefully from the adjoining direction.
  • Make a test cut in an offcut when working with an unfamiliar blade or sensitive surface material.
  • Remove dust from the guide columns and magnetic blade area regularly to maintain smooth operation.

How to Use

  • Switch off and disconnect the OS 400 VECTURO from the power supply.
  • Select a compatible plunge-cut saw blade suitable for the workpiece material and required cutting depth.
  • Inspect the blade, positioning aid and mounting adapter for wear or damage.
  • Fit the saw blade securely to the OS 400 according to the machine instructions.
  • Attach the OS-AH positioning aid using the tool-free adapter.
  • Adjust the position of the guide to suit the required cutting direction.
  • Confirm that the blade is held correctly by the magnetic catch and moves freely through the guide base.
  • Mark the required plunge cut or complete cut-out on the workpiece.
  • Secure and support the workpiece so that it cannot move during cutting.
  • Place the rubberised base pad flat against the workpiece.
  • Align the saw blade precisely with the marked cutting line.
  • Hold the positioning aid firmly against the surface and switch on the OS 400.
  • Allow the machine to reach operating speed before beginning the plunge movement.
  • Lower the machine gradually along the guide columns while maintaining steady control.
  • Do not exceed the maximum guided plunge depth of 60mm.
  • Complete the cut and withdraw the blade carefully while the machine remains under control.
  • Switch off the machine and wait for the blade to stop completely before lifting the guide from the surface.
  • Disconnect the tool before changing the blade or removing the positioning aid.

Features

  • Guided plunge base: Supports the machine and controls blade movement during plunge cutting.
  • Magnetic blade catch: Stabilises the blade and assists with accurate positioning on the scribe mark.
  • Parallel guide columns: Help maintain perpendicular blade movement as the machine is lowered.
  • Tool-free mounting adapter: Allows the positioning aid or compatible depth stop to be attached quickly.
  • Multiple angle settings: Enables the positioning aid to be adjusted for different working positions.
  • Rubberised base pad: Provides grip and reduces the risk of marking sensitive surfaces.
  • 60mm maximum plunge depth: Accommodates suitable long plunge-cut saw blades within the stated capacity.
  • Compact accessory design: Adds control without requiring a large routing or cutting template.

Benefits

  • Improved cutting accuracy: The blade can be positioned directly on the marked line before entering the material.
  • Greater plunge-cut control: The guide columns reduce sideways blade movement and help maintain a square cut.
  • Cleaner visible surfaces: The controlled blade entry helps limit unnecessary scratching and splintering.
  • Faster preparation: Tool-free mounting reduces the time required to change between freehand and guided cutting.
  • Safer machine positioning: The stable base gives the operator a defined support point before starting the plunge cut.
  • Useful for installed components: Ideal for producing openings where conventional saws or routers are difficult to position.
  • Reduced finishing work: Accurate cuts can minimise the filing, sanding or correction needed afterwards.
  • Protects delicate workpieces: The rubberised pad helps prevent the guide base from scratching the surface.

Application

  • Precision plunge cuts along marked lines.
  • Creating rectangular cut-outs in panels and fitted components.
  • Cutting openings in delicate or visible surfaces.
  • Producing perpendicular plunge cuts with the OS 400 VECTURO.
  • Furniture, cabinet and kitchen installation.

Safety

  • Wear suitable eye and hearing protection while operating the oscillating tool.
  • Use respiratory protection and suitable extraction where the material produces harmful dust.
  • Disconnect the OS 400 from the power supply before fitting, removing or adjusting the positioning aid or saw blade.
  • Use the positioning aid only with the Festool OS 400 and compatible accessories.
  • Inspect the guide, adapter, magnetic catch and saw blade before every use.
  • Do not use the accessory if any component is bent, cracked, loose or damaged.
  • Confirm that the positioning aid and saw blade are mounted securely before starting the machine.
  • Secure and support the workpiece firmly before making a plunge cut.
  • Check the cutting area for hidden cables, pipes, screws and other obstructions.
  • Keep hands away from the blade path and the underside of the workpiece.
  • Keep the guide base flat against the workpiece throughout the plunge cut.
  • Do not exceed the maximum guided plunge depth of 60mm.
  • Do not apply excessive pressure or force the blade through the material.
  • Stop the machine immediately if the blade bends, jams or becomes unstable.
  • Allow the blade to stop completely before lifting the positioning aid from the workpiece.
  • Do not touch the saw blade immediately after cutting, as it may be hot.
