Cutting Insert 3040 20 cm for Polystyrene Knife XTREME 2899

Replacement cutting insert 3040 with a 20 cm blade length designed for the XTREME 2899 polystyrene knife. This cutting insert provides the sharp edge required for precise straight cuts in EPS and XPS foam panels and blocks. As a spare part, it restores the original cutting performance of the XTREME 2899 tool, ensuring consistent slicing results for construction, insulation installation and model-making applications.

Advantages

The 20 cm blade delivers a long, stable cutting edge that supports even, continuous strokes across foam surfaces. Made to fit the XTREME 2899 system, the insert simplifies replacement and reduces downtime compared with sharpening or repairing a worn blade. Its geometry is optimized for reduced drag in polystyrene materials, maintaining straight cuts and minimal surface tearing.

Suitable for

• Cutting expanded polystyrene (EPS) panels and blocks
• Cutting extruded polystyrene (XPS) insulation boards
• On-site insulation trimming and fitting
• Model-making and prototyping with foam materials
• Restoring cutting performance of XTREME 2899 tools

Key specifications

• Blade length: 20 cm
• Compatibility: designed for XTREME 2899 polystyrene knife
• Intended material: EPS and XPS foam
• Function: straight cutting insert / replacement blade

How to use

Turn off and, if applicable, disconnect the XTREME 2899 tool before replacing the insert. Remove the worn insert following the tool manufacturer’s instructions and install the 20 cm cutting insert until it is securely seated. Ensure the blade is aligned and locked in place before powering or using the knife. For best results, feed the blade steadily through the foam with consistent speed and pressure to achieve straight, clean cuts.

Usage recommendations

Use appropriate personal protective equipment such as gloves and eye protection when replacing the insert and during cutting operations. Inspect the insert regularly for wear and replace it when edge deterioration affects cut quality. Store spare inserts in a dry, protected place to avoid damage.
