Festool FSK 420 Cross-Cutting Guide Rail 420mm

At a Glance: 420mm cross-cutting guide rail with -60° to +60° angle range, retract function and splinter guard

The Festool FSK 420 cross-cutting guide rail turns compatible Festool circular saws and plunge-cut saws into a portable, accurate and easy-to-use cross-cutting system. Designed for fast, repeatable straight and angled cuts, it connects to the saw with a quick-release fastener and returns the saw to the starting position after the cut. With an integrated splinter guard, adhesive cushion strips and smooth slideway lining, the FSK 420 is a compact but powerful guide rail solution for accurate trimming, board cutting and site work.

Portable compound mitre saw accuracy

The FSK 420 combines with compatible Festool saws to create a mobile mitre-saw style system for precise, repeatable cross cuts and angle cuts. It is ideal when you need guided accuracy without carrying a stationary saw setup around the jobsite.

Product highlights

  • 420mm cutting length Compact and practical for accurate cross cuts on boards, battens and sheet materials.
  • Flexible angle range Adjustable from -60° to +60° for repeatable angled cuts.
  • Quick-release saw connection Compatible saws connect quickly to form a single guided cutting unit.
  • Automatic retract function Returns the saw to the starting position after the cut.
  • Splinter guard Helps produce cleaner, splinter-free cuts along the scribe line.

  • Compatible machines include HKC 55, HKC 55 K, HK 55, HK 85, TS 60 K and TSV 60 K.
  • The rail connects to the saw using a quick-release fastener for fast setup and removal.
  • The retract function brings the saw back to the start position after the cut.
  • The adhesive cushion strips help protect the workpiece surface and improve rail grip.
  • The included FSZ 120 fastening clamp can be used in the guide rail groove for extra secure fixing.

Pro Tips

  • Use the locking angle positions for common repeat cuts to save time and improve consistency.
  • Keep the adhesive cushion strips clean so the rail grips properly and does not mark the workpiece.
  • Use the included clamp when cutting narrow, smooth or awkward materials where the rail could move.
  • Let the retract function return the saw fully before lifting the system from the workpiece.
  • For visible surfaces, align the splinter guard carefully with the marked cut line for the cleanest edge.

  • Check that the saw is compatible with the FSK 420 cross-cutting guide rail.
  • Attach the saw to the rail using the quick-release fastener.
  • Set the required cutting angle using the angle scale and locking positions where applicable.
  • Place the guide rail on the workpiece with the splinter guard aligned to the cut line.
  • Use the FSZ 120 fastening clamp if extra fixing is required.
  • Start the saw and guide it smoothly through the cut along the rail.
  • Allow the retract function to return the saw to the starting position after the cut.
  • Switch off the saw and wait for the blade to stop fully before lifting the rail from the workpiece.
