Specialized Cutter Knife for Flexible Ducts

The specialized cutter knife is an essential tool for the correct assembly of ventilation ductwork. Standard utility knives or hand saws leave slanted and jagged edges, which can damage the rubber seals of diffuser boxes and manifolds during installation. This compact tool solves the problem by cutting the corrugated pipe perfectly at a 90-degree angle in one fluid motion. A smooth cut ensures a secure push-fit connection, preventing working pressure loss and whistling inside the system.

The tool is designed for intensive professional use. The lower part of the cutter consists of guide arcs strictly calibrated for specific pipe diameters. The central blade is secured with screws: once it becomes dull, it can be easily replaced with a new one, making the tool highly durable and suitable for long-term use on construction sites.

Key Features and Benefits

• Seal protection and airtightness. A precise cut along the corrugation groove prevents burrs that could slice or crease the rubber rings during node assembly.
• High installation speed. The shape of the guides eliminates the need to pre-mark the pipe. The cutter automatically aligns with the correct groove, significantly reducing working time.
• On-site safety. The sharp blade is positioned between the guide arcs of the tool. This minimizes the risk of accidental slipping and hand injuries when cutting rigid plastic.
• Precise calibration. The tool is available in four modifications (50, 63, 75, and 90 mm), providing a tight grip on the pipe without play or blade misalignment.
