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.

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.

Extra Information

The FSK 420 is designed for selected Festool portable circular saws and plunge-cut saws.
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.

How to Use

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.
