BOSCH NNI500 Electric Sheet Metal Nibbler 500W

The BOSCH NNI500 nibbler redefines precision cutting in sheet metal work with its punch-and-die mechanism that slices through steel up to 2.5 mm, stainless steel up to 1.2 mm, and aluminum up to 2.5 mm without distorting the material. Unlike traditional shears that can warp thin sheets, this tool delivers clean, burr-free edges and a tight 45 mm minimum cutting radius, making it ideal for curves, cutouts, and intricate profiles.

Highlights

• Powerful 500 W motor for continuous heavy-duty cutting
• No-load stroke rate of 2000 strokes/min for fast, smooth operation
• Versatile material compatibility: steel, stainless steel, and aluminum
• Compact punch and die system (5 mm punch, 20 mm die) for precise nibbling
• Ergonomic design with low vibration (10.5 m/s²) for comfortable handling
• Includes spare punch, spare die, and hex key for maintenance

In daily use

On the jobsite or in the workshop, the NNI500 excels at cutting corrugated sheets, trapezoidal profiles, and flat panels. Its 3-meter power cable provides ample reach, while the double-insulated construction (Protection Class II) ensures safety without the need for grounding. The nibbler's ability to start cuts from a pre-drilled hole or from the edge makes it perfect for creating openings for vents, pipes, or electrical boxes. The low weight and balanced body reduce fatigue during overhead or vertical cutting tasks, and the included spare punch and die extend the tool's service life, minimizing downtime.
