Festool ISC 240 18V Insulation Saw (2x 4Ah High-power)

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.

Comes With

  • 2x 18V 4Ah high-power batteries:
    • Lithium high-power cell technology ensures high power in demanding applications
    • 50% more compact than the 5.2Ah battery for working in confined spaces
    • 20% lighter than the 5.2Ah battery for working over long periods of time or overhead
    • Bluetooth technology communicates with the Bluetooth module on your Festool dust extractor so that when you switch your cordless tool on/off, your extractor will automatically start/stop as well
  • TCL 6 rapid battery charger
  • 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

NEW & Improved Secure Deliveries

PIN code verification at your doorstep

We've improved the security of our deliveries to you with DPD's PIN code verification system. We will be using this service on most orders to ensure your parcel gets to you securely.

You will receive a PIN code via text and/or email which you must recite to the delivery driver on arrival. If someone is receiving the parcel on your behalf, remember to pass on the code to them. The driver can also resend the PIN code to the original contact on arrival if required. This service requires a mobile phone number with your order so please ensure you provide one to take advantage.


- Our deliveries are very easy to track, plus you'll get a handy 1 hour delivery window so you know when to expect your items. You'll receive a tracking number with your 'order dispatched' email.

- Your VAT invoice is always in the box with your goods.

- Your goods are always securely packaged when leaving our warehouse. We strive to ensure your goods reach you in prime condition.

Our main courier is DPD. We use DPD for the vast majority of our deliveries. APC and TNT handle other specific types of deliveries for us. In poor weather conditions our couriers may experience delays that are out of our control, however we will help you in every way possible to track delivery progress.

- Delivery to construction/job sites is possible, but done so at your own risk. Our service can deliver to an address, but we can't guarantee delivery to a specific person or location at the address. For the best outcome, please provide detailed courier instructions and a contact number that we can pass on to the courier.

- Delivery to 'safe place' is not available for most orders, someone must be present to receive your delivery. We do this to ensure our couriers deliver to the right person at the right address, to ensure your goods are not lost or stolen. Particularly as most orders are of high value.
