Specifications

Precision & Cutting Performance

The KAPEX KS 120 is designed around precision. Its twin-column guide system uses dual ball bearings to provide stable and smooth blade movement, while the dual-line laser marks the cutting width directly on the workpiece.

Fine adjustment controls allow precise angle positioning, helping professional tradespeople achieve accurate results when working with trim, molding, coving, cornices, and other detailed materials.

Cutting Capacity & Special Applications

The KS 120’s special cutting position allows the saw to increase its cutting depth from 88 mm to up to 120 mm without requiring a blade change.

This expanded capacity allows strip material to be cut vertically against the stop and enables coving and cornices to be cut in their original wall position, helping reduce setup time for specialized trim applications.

Safety & Control Features

• Quick-acting brake helps stop the blade rapidly after operation.
• Smooth start-up helps provide controlled tool activation.
• Overload protection helps protect the tool during demanding applications.
• Transport safety device helps secure the saw during movement.
• Ergonomic handles provide comfortable handling for both left- and right-handed users.
• Front-accessible controls reduce the need to reach around the machine.
• Always use appropriate eye and hearing protection and follow Festool’s operating and safety instructions.

Mobility & Workshop Setup

Static & Transport Frame

The optional KAPEX base frame can convert the saw into a mobile sawing station. The supplied description states that the frame can be converted in three hand movements and provides a trimming length of up to 2.40 m, including the trimming attachment.

MFT 3 Compatibility

The KAPEX can be positioned on the perforated top of the MFT 3 multifunction table and secured using the appropriate clamping kit, providing a practical elevated workstation for users who prefer to work while standing.

Ergonomic Design

• Compact footprint with no protruding guide rods.
• Lightweight 47.39-lb. design.
• Ergonomic handles for left- and right-handed users.
