Festool ISC240 18V Insulating Material Saw (Naked, Systainer)

The Festool ISC 240 cordless 18V insulating material saw is extremely mobile, efficient and versatile making it the best solution for anyone who wishes to insulate housing with minimum effort! It can be used for freehand or guided cutting; on roofing, scaffolding or flooring; and with flexible or PUR/PIR insulating materials like Celotex.

The Festool ISC 240 Basic Comes With

  • Festool ISC 240 body only (batteries and charger not included)
  • Systainer SYS3 M 237 carry case
    • Connects with other Systainers to form one tidy stack for easier storage and transportation
    • Compatible with Bott Vario3 vehicle equipment for easier storage and organisation in your work van
  • 240mm serrated cutting set for flexible mineral and natural fibre materials (if you're cutting PUR/PIR or polystyrene materials like Celotex then you'll need this cross-set cutting set)
  • Guide rail slide
  • Adapter table

Ideal Applications

  • Cutting flexible insulating materials, such as glass wool, rock wool and natural fibres (with the included serrated cutting set)
  • Cutting PUR/PIR and polystyrene insulation boards like Celotex (with this cross-set cutting set)
  • Cable-free cutting where there is no power source or where this is difficult to access, e.g. outdoors, on scaffolding, etc.
  • Ideal for mobile use in assembly applications
  • Cutting flexible insulating materials with precise angles and accurate dimensions (with a guide rail and angle stop)

Best Features of the Festool ISC 240 Insulation Saw

  • Extremely versatile - can be used for freehand cutting or guided cutting with a guide rail and angle stop to make repeat cuts that are perfectly straight or precisely angled
  • The perfectly coordinated serrated cutting set enables fast, clean and precise cutting of flexible mineral and natural fibre materials up to 240mm (if you're cutting PUR/PIR or polystyrene materials like Celotex then you'll need this cross-set cutting set)
  • Cut even the thickest insulating materials effortlessly with these longer 350mm cutting sets
  • Extremely mobile and ergonomic - this Festool insulation saw has no cable, low weight, perfect balance and rubber handle areas for maximum comfort, even with one-handed operation
  • Brushless EC-TEC motor for maximum performance and efficiency:
    • Generates an extraordinary amount of power while consuming extremely low amounts of energy
    • Runs wear-free without carbon brushes and is therefore maintenance-free for a longer service life
  • High speed with little effort thanks to the combination of powerful 18V battery technology and a brushless motor
  • Electronic speed control for adjusting to all types of materials
  • The blade has an extra-long service life for heavy-duty work
  • Dust extraction for a healthy and clean work environment - the Cleantec bayonet fitting ensures that the suction hose doesn't slip out
  • Extremely robust - a grille protects the motor against dust and fibres for high durability
  • Double-click protective function prevents unintentional switch-on for increased safety
  • FastFix interface for tool-free cutting set changes
