Festool SG-350/W-ISC Serrated Cutting Set

At a Glance: 350mm serrated cutting set for the Festool ISC 240 cordless insulation saw, designed for clean and efficient cutting of flexible mineral-fibre and natural-fibre insulation.

The Festool SG-350/W-ISC Serrated Cutting Set is designed for accurate, controlled cutting of flexible insulating materials with the Festool ISC 240 cordless insulation saw. It is ideal for processing glass wool, rock wool, hemp and soft wood-fibre insulation with material thicknesses of up to 350mm.

The cutting set combines one fixed serrated blade with one movable serrated blade. This coordinated cutting action makes it easier to guide the saw through soft, flexible insulation without excessively compressing or tearing the material. An innovative adjustment mechanism allows the blade setting to be adapted to suit different insulation types and densities.

Installation is fast and convenient thanks to the ISC 240 quick-change system, which allows the complete cutting set to be fitted or removed without tools. The serrated blade is also easy to replace, helping minimise downtime when maintenance is required.

Precise cutting for flexible insulation up to 350mm thick

The SG-350/W-ISC is the application-specific cutting set for flexible mineral-fibre and natural-fibre insulation. It supports straight, controlled cutting during timber-frame construction, between-rafter insulation and general timber-building applications.

Product Highlights

  • 350mm cutting capacity: Suitable for flexible insulation materials up to 350mm thick.
  • Serrated cutting system: One fixed and one movable blade work together for controlled cutting through soft insulation.
  • Material-specific adjustment: Blade setting can be adapted to suit different flexible insulating materials.
  • Tool-free installation: Fits quickly onto the Festool ISC 240 using its quick-change system.
  • Protected cutting set: The upper mandrel helps protect the serrated blade and supporting surface from accidental damage.
  • Guide-rail compatible: Can be attached to the guide-rail carriage for guided, repeatable cuts.
  • Replaceable serrated blade: The cutting blade can be changed easily when worn.
  • Hardened cutting edges: Inductively hardened blade edges support durability and reliable cutting performance.

Extra Information

  • The SG-350/W-ISC is designed specifically for the Festool ISC 240 EB cordless insulating-material saw.
  • The letter W identifies the serrated cutting-set version for flexible insulation materials.
  • The cutting set is suitable for flexible mineral-fibre and natural-fibre insulation.
  • Typical materials include glass wool, rock wool, hemp and soft wood-fibre insulation.
  • The maximum cutting length is 350mm.
  • The blade setting can be adjusted to suit the material being cut.
  • The complete cutting set can be installed and removed without tools.
  • For guided cutting, the set can be attached to the compatible guide-rail carriage.
  • When cutting dust-producing insulation, suitable extraction can be connected to the ISC 240 using the appropriate extraction adapter.
  • This serrated cutting set is not suitable for pressure-resistant wood-fibre insulating materials.
  • For rigid PUR insulation, polystyrene and other pressure-resistant insulation, use the appropriate Festool cross-set cutting set.

Pro Tips

  • Adjust the blade setting to match the density and flexibility of the insulation before beginning the final cuts.
  • Make a test cut on an offcut to confirm the correct blade adjustment and feed speed.
  • Support flexible insulation on a clean, flat surface to reduce movement while cutting.
  • Use the guide-rail carriage when long, straight or repeatable cuts are required.
  • Allow the moving blade to do the work rather than forcing the saw through the material.
  • Keep the serrated blade clean and free from trapped fibres to maintain smooth cutting performance.
  • Replace the blade when cutting becomes slower, uneven or requires noticeably more pressure.
  • Use suitable dust extraction and respiratory protection when processing dusty mineral-fibre insulation.

How to Use

  • Remove the battery pack from the Festool ISC 240 before fitting or adjusting the cutting set.
  • Inspect the cutting set and serrated blades for damage, deformation or excessive wear.
  • Align the SG-350/W-ISC with the cutting-set interface on the ISC 240.
  • Fit the cutting set using the machine's tool-free quick-change mechanism.
  • Check that the cutting set is fully seated and securely locked.
  • Adjust the blade setting according to the type and density of the insulation material.
  • Mark the required cutting line and support the insulation securely.
  • Attach the guide-rail carriage where guided cutting is required.
  • Reconnect the battery pack and position the cutting set at the edge of the material.
  • Start the saw and guide it smoothly through the insulation without excessive pressure.
  • Allow the blades to stop completely before lifting the saw from the workpiece.
  • Remove accumulated fibres and inspect the cutting set after use.

Features

  • Dual-blade construction: Uses one stationary and one reciprocating serrated blade.
  • 350mm cutting length: Designed for thick layers of flexible insulating material.
  • Adjustable blade setting: Allows cutting performance to be matched to the material being processed.
  • Quick-change interface: Enables tool-free fitting and removal from the ISC 240.
  • Inductively hardened teeth: Provides durable cutting edges for professional use.
  • Protective upper mandrel: Helps prevent accidental contact between the cutting blade and surrounding surfaces.
  • Guided-cut compatibility: Can be used with the dedicated guide-rail carriage.
  • Serviceable design: The serrated blade can be replaced separately when required.

Benefits

  • Cleaner insulation cuts: Reduces uncontrolled tearing and deformation of soft insulating materials.
  • Better fitting insulation: Accurate cuts help insulation fit neatly between rafters, studs and framing members.
  • Fast material changes: Tool-free replacement makes it easy to switch between different ISC cutting sets.
  • Improved cutting control: Adjustable blade spacing helps accommodate different material structures and densities.
  • Reduced downtime: Easy blade replacement simplifies maintenance on site or in the workshop.
  • Safer surface contact: The protective mandrel helps reduce accidental damage to the blade and supporting base.
  • Repeatable straight cuts: Compatibility with the guide-rail carriage supports accurate guided work.
  • Professional versatility: Suitable for a range of flexible mineral and natural insulation products.

Application

  • Cutting flexible glass-wool insulation.
  • Cutting flexible rock-wool insulation.
  • Cutting hemp insulation.
  • Cutting soft wood-fibre insulating material.
  • Between-rafter insulation installation.
  • Timber-frame construction.
  • Timber construction and carpentry.
  • Cutting flexible insulation up to 350mm thick.

Safety

  • Wear suitable eye, respiratory and protective work equipment when cutting insulating materials.
  • Remove the battery pack from the ISC 240 before installing, removing, cleaning or adjusting the cutting set.
  • Inspect the serrated blades and cutting-set body before every use.
  • Do not use the cutting set if a blade is bent, cracked, loose or excessively worn.
  • Confirm that the cutting set is fully engaged in the tool-free mounting system before operating the saw.
  • Keep hands and loose clothing clear of the moving blades.
  • Secure and support the insulation material to prevent unexpected movement during cutting.
  • Do not force or twist the cutting set inside the material.
  • Use suitable dust extraction and respiratory protection when cutting mineral-fibre products that generate airborne dust.
  • Do not use this cutting set for pressure-resistant wood-fibre insulation or other unsuitable rigid materials.
  • Allow the blades to stop completely before placing the saw down or removing trapped material.
  • Follow all operating, maintenance and safety instructions supplied with the Festool ISC 240.
