Electric sheet metal shears Bosch NNI500 500W stroke, model NNI500

The Bosch NNI500 Electric Sheet Metal Shears is a handheld tool with a 500W motor and stroke action designed for cutting thin sheet metal. It is intended for straight and curved cuts in sheet panels, HVAC ductwork, vehicle body panels and general repair tasks. The tool provides continuous power for repetitive shearing operations and is suitable for workshop and professional repair use where controlled, accurate metal cutting is required.

Advantages

The Bosch NNI500 combines a compact handheld design with a high-reliability 500W motor that delivers steady cutting force for thin sheet materials. Its stroke mechanism enables precise straight and curved cuts while reducing user fatigue compared with manual shears. The tool is designed for consistent cutting performance over repeated operations and provides good control for finishing edges and preparing panels for assembly or repair.

Suitable for

• Cutting thin steel and aluminum panels in HVAC and ductwork fabrication
• Automotive bodywork repair and shaping of vehicle panels
• Workshop and maintenance tasks requiring repetitive, controlled metal cuts
• Cutting shaped openings and trimming sheet metal for installations

Key specifications

• Motor power: 500 W
• Tool type: Handheld electric sheet metal shears with stroke action
• Cutting modes: Straight and curved cuts in thin sheet metal
• Typical material compatibility: Thin steel and aluminum sheets
• Intended use: Continuous operation for repetitive shearing tasks in workshops and repair jobs

How to use

Secure the sheet material and mark the intended cut line. Fit the appropriate blade or cutting attachment if the tool offers replaceable blades, and check that all fastenings are tightened. Hold the Bosch NNI500 firmly with both hands and position the cutting edge on the marked line. Operate the tool at a steady pace, allowing the stroke action to shear the metal without forcing the tool. After each cut, inspect the edge and remove any burrs or sharp edges with a file or deburring tool as needed. Disconnect the tool from the power source before changing blades or performing maintenance.

Usage recommendations

For safe and effective results, use appropriate personal protective equipment such as safety glasses, gloves and hearing protection. Match the blade type to the sheet material and thickness, and avoid attempting to cut material beyond the tool's intended thin-sheet capacity. Maintain blades sharp and replace them when wear affects cut quality; regular inspection and basic maintenance will extend tool life and ensure consistent cutting performance.
