Tesoura para chapa Bosch GNA 18V-16 E 1400 spm 700 W preto azul

The Bosch GNA 18V-16 E power shear is a cordless cutting tool designed for controlled straight and curved cuts in sheet metal. Equipped with a brushless motor and powered by an 18 V battery, it delivers up to 1,400 strokes per minute and a cutting capacity of 1.6 mm in steel while maintaining a low overall weight of approximately 1.7 kg. The tool accepts a minimum cutting radius of 4 cm, allowing for precise work on panels, ducts and other thin metal materials.

Advantages

The brushless motor increases efficiency and reduces maintenance needs compared with brushed alternatives, providing a longer runtime per battery charge. High stroke rate and compact, lightweight design improve handling and reduce operator fatigue during extended use. A minimum cutting radius of 4 cm enables tighter curves, and the cordless 18 V power supply delivers portability for on-site work without trailing cables.

Suitable for

• Cutting sheet steel and thin metal panels up to 1.6 mm thickness
• Making straight and curved cuts in HVAC ducts and ventilation components
• Automotive bodywork trimming and repair of metal panels
• On-site installations and maintenance where cordless mobility is required

Key specifications

• Power source: 18 V battery (cordless)
• Motor type: brushless
• Maximum idle stroke rate: 1,400 spm (strokes per minute)
• Maximum cutting capacity in steel: 1.6 mm
• Minimum cutting radius: 4 cm
• Approximate weight: 1.7 kg

How to use

Before use, ensure the correct battery is fully charged and securely fitted. Mark the cut line on the sheet metal and position the shear so the blade engages at the start point. Apply steady pressure and guide the tool along the marked path, allowing the blade to perform the cutting action; avoid forcing the tool beyond its rated cutting capacity. For curved cuts, maintain a consistent feed rate and use the specified minimum cutting radius to prevent tool binding or material distortion. After finishing, clean metal shavings from the cutting area and store the tool with the battery removed.

Recommendations

Use appropriate personal protective equipment such as safety glasses, cut-resistant gloves and hearing protection. Choose an 18 V battery with sufficient capacity for the expected workload to maximize runtime. For thicker or hardened steels, use a different cutting method suited to higher material thicknesses. Regularly inspect blades for wear and replace them when cutting quality declines to maintain performance and safety.
