TRUMPF TruTool N 350: Electric Nibbler

TRUMPF TruTool N 350: Electric Nibbler


TruTool N 350 is an electric handheld nibbler from TRUMPF, designed for processing sheet metal (flat and profiled sheets). The tool uses a hollow round punch that allows the tool to rotate “on the spot” () for internal cutouts, notches, and curved elements.

It offers high productivity thanks to a powerful motor, variable stroke rate, quick tool-free punch/die change, and an ergonomic body.

The TruTool N 350 is intended for use in construction, ventilation, facade systems, installation, processing of tanks and containers, technical openings, metal trimming in architectural structures, etc.

Features and Advantages  
  • On-the-Spot Rotation — Hollow Round Punch: Thanks to the hollow round punch, the tool can be rotated without changing the position of the tool itself—useful for internal cutouts, holes, and curved contours.

  • Powerful Motor with Protection: motor with electronic overload protection and soft start (inrush current limitation).

  • Tool-Free Punch/Die Change: Instrumental elements can be quickly removed and installed without the use of additional wrenches, reducing downtime.

  • Adjustable Speed: The speed controller allows the stroke rate to be adapted to the material, cutting precision, or template.

  • Robust Ergonomics and Comfortable Grip: The body shape, optimal handle diameter, and balance contribute to comfortable operation.

  • Stainless Steel Support: Via CR-versions of the punch/die (special tools for high-strength material).

  • Distortion-Free Cutting: The nibbling process avoids thermal changes or edge deformation, which is especially important for thin and sheet metal.

Standard Equipment  
  • TruTool N 350—main tool (electric housing, mechanics).

  • Integrated standard punch.

  • Integrated standard die.

  • Tube of grease () for tool lubrication.

  • Handle for holding the tool.

  • Protective case (TRUMPF Box M3 or equivalent) for storage and transport.

  • Operating instructions / user manual.

Options  
  • CR-versions of punch/die for high-strength steels (e.g., CR tools for processing sheets with strength above standard).

  • Chip bag—ensures safe removal of swarf from the work area.

  • Suspension eyelet—allows the tool to be hung on a balancer or lifting system.

  • Gaskets / spacer sleeves for thin sheets (for sheets up to ) to ensure better tool contact.

  • Special oils / lubricants for cutting steel or aluminum—improve cut quality and extend tool lifespan.
