Festool ISC 240 EB-Basic Cordless Insulating-Material Saw
At a Glance: 18 V cordless insulation saw with 240 mm cutting depth, EC-TEC motor, FastFix cutting-set change and Systainer³ storage
The Festool ISC 240 EB-Basic is a professional cordless insulating-material saw designed for clean, fast and controlled cutting of insulation materials on site. Whether working on roofing, scaffolding, flooring, installation or general insulation work, this compact 18 V saw gives excellent freedom of movement without a cable getting in the way. With its brushless EC-TEC motor, perfectly coordinated cutting sets, 240 mm cutting depth and guide rail compatibility, the ISC 240 is built for efficient cutting of flexible mineral and natural fibre insulation, as well as PUR and polystyrene insulating boards when fitted with the correct cutting set.
The ISC 240 EB-Basic is made for tradespeople who cut insulation regularly and need better results than a knife or hand saw can provide. It delivers cleaner cuts, better dimensional accuracy and less physical effort, especially when used with a guide rail and angle stop for repeatable straight or angled cuts.
Product highlights
- Cordless insulation cutting: Ideal for work outdoors, on scaffolding, on roofs or where power access is inconvenient.
- 240 mm cutting depth: Suitable for many common insulation-board and mineral-wool cutting applications.
- Brushless EC-TEC motor: Provides strong cutting power with efficient battery use and low maintenance.
- FastFix cutting-set change: Allows tool-free cutting-set changes for quicker material-specific setup.
- Guide rail compatible: Supports accurate straight cuts and repeatable angled cuts when used with compatible Festool guide rail accessories.
- CLEANTEC extraction connection: 27 mm dust extraction connection for cleaner cutting where extraction is required.
- Lightweight handling: Balanced design and low weight help reduce fatigue, even during one-handed operation.
- Basic version: Supplied without battery pack and charger, ideal for users already on the Festool 18 V battery platform.
Extra Information
- This is the Basic version and is supplied without battery pack and charger.
- The included SG-240/W-ISC cutting set is suited to flexible insulating materials such as mineral wool and natural fibre insulation.
- For rigid insulation such as PUR and polystyrene boards, use the correct cross-set cutting set for the material.
- The ISC 240 can be used freehand or with a Festool guide rail and stop system for more accurate cuts.
- The 27 mm dust extraction connection allows connection to a suitable Festool dust extractor where dust control is required.
- For best cordless performance, use compatible Festool 18 V battery packs suited to the application.
Pro Tips
- Use the guide rail slide when straight, repeatable cuts are needed. Insulation may be soft, but wonky cuts still show up during fitting.
- Match the cutting set to the insulation type. Flexible mineral wool and rigid foam boards need different blade styles for best results.
- Let the saw cut at its own pace. Forcing it can compress soft insulation and reduce cut quality.
- Use the FS-WA-ISC angle stop with a guide rail when cutting repeated angled pieces for roof or framing work.
- Keep the cutting set clean and inspect it regularly. Dull or damaged blades make insulation cutting messy very quickly.
How to Use
- Select the correct cutting set for the insulation material being cut.
- Remove the battery pack before fitting or changing the cutting set.
- Fit the cutting set using the FastFix system and make sure it is securely locked in place.
- Attach the adapter table or guide rail slide if the application requires guided cutting.
- Connect a suitable dust extractor to the 27 mm extraction connection where dust extraction is required.
- Insert a compatible Festool 18 V battery pack.
- Mark the cutting line clearly on the insulation material.
- Place the saw on the material or guide rail and start the machine before entering the cut.
- Guide the saw steadily through the material without forcing or compressing the insulation.
- Allow the cutting set to stop completely before setting the tool down or changing accessories.
Features
- 18 V battery drive: Gives full cordless mobility for insulation work on site.
- 3 000 min⁻¹ stroke rate: Delivers fast cutting progress through suitable insulation materials.
- 26 mm stroke length: Supports efficient sawing action through thicker insulation materials.
- SG-240/W-ISC cutting set included: Suitable for cutting flexible mineral and natural fibre insulation materials.
- Tool-free cutting-set change: FastFix system makes it easier to adapt the saw to the material being cut.
- Guide rail slide included: Allows the saw to be used with compatible Festool guide rails for straight, controlled cuts.
- Adapter table included: Supports more controlled cutting and system use.
- Systainer³ storage: Keeps the machine and accessories protected, organised and easy to transport.
Benefits
- Cleaner insulation cuts: The guided cutting system helps produce straighter, neater cuts than freehand knife work.
- Less physical effort: The saw does the cutting work, reducing fatigue on larger insulation jobs.
- Better site mobility: Cordless operation makes it practical for roofing, scaffolding, outdoor and installation work.
- More accurate fitting: Insulation can be cut to size more precisely, helping reduce gaps and wasted material.
- Material flexibility: Different cutting sets allow the saw to be adapted for flexible insulation or rigid foam boards.
- Professional system workflow: Works with Festool guide rails, angle stop accessories, dust extraction and Systainer storage.
Application
- Cutting flexible insulating materials such as glass wool, rock wool and natural fibres
- Cutting PUR polyurethane hard foam insulation boards with the correct cutting set
- Cutting polystyrene insulating boards with the correct cutting set
- Cordless cutting where no power connection is available or easy to access
- Outdoor insulation work, roofing work and scaffolding applications
- Mobile insulation cutting during assembly and installation work
- Cutting insulation with precise angles when used with guide rail and FS-WA-ISC angle stop
- Timber construction, roofing, flooring and general building insulation work
Safety
- Wear eye, ear and dust protection when cutting insulation materials.
- Use the correct cutting set for the material being cut.
- Remove the battery pack before changing cutting sets, fitting accessories or cleaning the tool.
- Make sure the cutting set is correctly fitted and locked before starting the saw.
- Keep hands clear of the cutting set and cutting line during operation.
- Support the insulation material properly so it does not shift, compress or tear during cutting.
- Use dust extraction and suitable respiratory protection when cutting materials that create dust or loose fibres.
- Do not force the saw through the material; use a steady feed rate for cleaner cutting.
- Allow the cutting set to stop completely before placing the tool down.
- Use only compatible Festool batteries, chargers, cutting sets and accessories.
