Tesoura para chapa Bosch GNA 18V-16 E 1400 spm 700 W sem escovas

The Bosch GNA 18V-16 E 1400 spm 700 W Brushless power shear is a cordless cutting tool designed for precise sheet-metal work. Powered by an 18 V battery and driven by a brushless motor, the tool delivers a no-load stroke rate of 1400 spm and a cutting capacity of up to 1.6 mm in steel. Weighing approximately 1.7 kg and featuring a minimum cutting radius of 4 cm, this shear is intended for controlled, accurate cuts in a variety of metalworking applications.

Advantages

The brushless motor provides improved efficiency and reduced maintenance compared with brushed alternatives, while the cordless design offers increased mobility on job sites without a power cord limiting reach. A high idle stroke rate enables faster progress through thin materials, and the combination of low weight and a compact cutting head supports fine maneuvering and reduced operator fatigue. The specified minimum cutting radius allows for tight curves and detailed work on sheet metal.

Suitable for

• Cutting thin steel sheets and panels up to 1.6 mm thickness
• Making curved and straight cuts with a minimum radius of 4 cm
• On-site repair and modification tasks where cordless operation is required
• Sheet-metal fabrication, HVAC ductwork trimming and maintenance

Key specifications

• Power source: 18 V battery (cordless)
• Motor type: brushless
• No-load stroke rate: 1400 strokes per minute (spm)
• Rated power: 700 W
• Maximum cutting capacity in steel: 1.6 mm
• Minimum cutting radius: 4 cm
• Weight: approximately 1.7 kg

How to use

Ensure the battery is fully charged before operation and select appropriate personal protective equipment, including eye and hand protection. Secure the workpiece to prevent movement, mark the cut line, and position the shear so the cutting head follows the marked path. Start the tool and proceed steadily along the line, allowing the blade and motor speed to perform the cut without forcing the tool. For curved cuts, maintain a consistent feed speed and keep the minimum radius in mind. After finishing, turn off the tool and remove the battery before performing any blade inspection or maintenance.

Recommendations

Use blades and accessories specified for thin steel sheet cutting and check blade condition regularly to maintain clean cuts. For prolonged cutting sessions, alternate work and inspection breaks to allow the tool to cool, and store the shear in a dry place when not in use.
