What they cut

  • 15 mm or less: corrugated board, folding carton, gasket and rubber.
  • 16 to 60 mm: foam board, corrugated plastic, honeycomb, carpet, rubber and triple wall corrugated.
  • Over 60 mm: foam, insulation and fibrous materials. CSR6831 cuts foam up to 80 mm thick.
  • Serrated CSR6352 and CW38: honeycomb, tough paper materials and foam. The serrated edge cuts with less friction, so the blade stays cooler.
