The revolution in insulating-material saws.

No matter whether freehand or guided with guide rail and stop system, whether working on roofing, scaffolding or flooring, with insulating material made of mineral fibres, natural fibres or PUR insulating boards – the ISC 240 impresses with its mobility, versatility and efficiency, making it the optimal solution for anyone wishing to insulate housing with minimum effort.

  • Perfectly coordinated cutting sets for precise and fast cutting of flexible mineral and natural fibre insulating materials as well as PUR insulating materials
  • Mobile, fast and saves effort without a cable: With a powerful 18 V Li-ion battery and brushless EC-TEC motor. Benefit from all the advantages of the Festool dust-free system thanks to Bluetooth® cordless technology
  • For cutting material efficiently: With the guide rail and angle stop (available in a set or as accessories), reproducible angled cuts can be made with precise dimensions
  • Work without tiring thanks to a perfectly balanced design and low weight – for maximum comfort when working, even in one-handed operation
  • Cut even the thickest insulating materials effortlessly: Thanks to the cutting set for cutting depths up to 350 mm
  • Replacement of the cutting sets without the need to use tools for efficient work adapted to the material

Product highlights

  • Achieve ideal results more quickly:

    Perfectly coordinated cutting sets enable fast, clean and precise cutting of flexible mineral and natural fibre insulating materials as well as PUR insulating boards.

  • Convenient and safe:

    Mobile cutting of insulating materials without a cable getting in your way. Whether in the workshop, on scaffolding or on the roof. The powerful 18 V Li-ion battery in combination with the brushless EC-TEC motor ensures high speed with little effort.

  • Systems get it done:

    Extremely versatile: Whether freehand cutting or guided cutting – thanks to the guide rail and angle stop (available in a set or as accessories), repeat cuts can be made dead straight and with precise angles.

Product details

  • Mobile and ergonomic

    Low weight, rubber handle areas and a perfectly balanced design – for maximum comfort when working, even in one-handed operation. The double-click protective function prevents the tool from being switched on accidentally for safety while working.

  • Versatile

    For flexible insulating materials such as mineral wool and natural fibres with serrated cutting set, for insulating materials such as PUR and styrofoam with cross-set cutting set. In two lengths (240 mm/350 mm) for different material thicknesses.

  • Quick and durable

    The cutting sets with special saw blades allow you to make rapid progress on your work with an extra-long service life, even with insulating materials up to 350 mm. Thanks to the quick-change system, the cutting set is replaced easily and without the need for tools in next to no time.

  • Extremely robust

    A grille protects the maintenance-free EC-TEC motor against dust and fibres and therefore makes it suitable for heavy-duty work on construction sites.

  • Low-dust work

    When cutting insulating materials that produce dust, a mobile dust extractor can be connected via the extraction adapter. For a dust-free and healthy working environment.

  • Cordless power

    The combination of brushless EC-TEC motor and 18 V Li-ion battery guarantees long-lasting performance and high traction.

  • Clean cutting surface

    With the guide rail and angle stop (available in a set or as accessories), repeat cuts can be made perfectly straight and with precise angles.

Main applications

  • For cutting flexible insulating materials such as glass wool, rock wool and natural fibres (with serrated saw blade cutting set)
  • For cutting PUR (polyurethane hard foam) and polystyrene insulating boards (with cross-set saw blade cutting set)
  • Cable-free cutting where there is no power connection or where this is difficult to access (e.g. outdoors, on scaffolding)
  • Ideal for mobile use in assembly applications
  • Cutting of flexible insulating materials with precise angles and accurate dimensions – when used together with the guide rail and the FS-WA-ISC angle stop
  • Alternate top bevel saw blade (W/PW)

Performance features

  • Lithium-ion battery

    Fitted with high-performance lithium ion battery pack.

  • EC-TEC motor

    The EC-TEC drive concept generates an extraordinary amount of power while consuming extremely low amounts of energy.


    Integrated bayonet fitting as the connecting element between the extractor and the tool.

  • Electronic

    Speed control for adjusting to all types of materials.

  • FastFix

    Makes changing routing, sawing, planing, sanding, drilling and screwdriving tools easier.


    Faster reuse of battery packs thanks to AIRSTREAM technology (cooling function for faster availability) and significantly increased charging capacity

  • Guide system

    Patented guide system for safe guidance of saws and router bits.
