The Story
Colex Universal Single Edge Knife – T00139
The Colex Universal Single Edge Knife (T00139) is a rigid tangential cutting tool engineered for materials up to ¼” thick. Designed for speed and precision, this knife excels at cutting foam board, honeycomb, expanded PVC, and corrugated plastic while maintaining clean edges and reduced blade deflection.
Why Choose the Universal Single Edge Knife?
Equipped with a 1.5mm thick blade, this tool provides exceptional rigidity during cutting. The increased blade strength reduces deflection and minimizes edge flaws — especially when working with ¼” and thinner honeycomb or foam board.
Compared to an oscillating knife, the T00139 can significantly reduce cutting time when processing ¼” and thinner materials, making it ideal for high-volume finishing environments.
Best For:
- Honeycomb board
- Corrugated plastic
- Foam board and rigid foam
- Expanded PVC (EPVC)
- PVC banner material
- Paper and cardstock
- Polyester fabric
- Carpet and tarp
