It delivers up to 3000 RPM idle speed and a rated torque suitable for driving screws up to 4 mm in diameter. The tool is powered by a 12V rechargeable battery with 2.5 Ah capacity and integrates an adjustable speed control and a built-in work light to assist in confined or poorly lit areas. With a lightweight construction of approximately 0.9 kg and compact dimensions, the unit is intended for practical day-to-day fastening work in workshops, service vehicles and on-site jobs.

Advantages

How to use

Charge the 12V battery fully before first use following the battery charger instructions provided by the manufacturer. Select the appropriate bit and insert it securely into the bit holder. Adjust the speed control to a low setting for small or delicate screws and increase speed for larger screws or when faster driving is needed. Position the screwdriver perpendicular to the screw head, apply steady pressure and engage the trigger. Use the integrated light to illuminate the work area as required. After use, remove the bit if necessary and store the tool and battery in a dry, dust-free place.

Recommendations

For best results, match the bit type and size to the screw head, avoid excessive torque on fragile materials, and use the adjustable speed to prevent stripping. Regularly inspect the bit holder and battery contacts for wear or debris, and follow manufacturer guidance for battery charging and storage to prolong battery life.
