Chave de impacto Metabo SSW 18 LTX 300 BL 1/2 polegadas 300 N⋅m 2650 rpm

The Metabo SSW 18 LTX 300 BL 1/2" impact wrench delivers up to 300 N·m of maximum torque with a no-load speed of 2650 RPM. Designed for use with an 18 V battery, this compact tool combines high power and low weight — at approximately 1.1 kg — making it suited for demanding fastening and loosening tasks where mobility and reduced operator fatigue matter. The unit features a 1/2" drive and a robust aluminum housing that balances durability and heat dissipation for extended use in professional and DIY environments.

Advantages

The brushless motor provides efficient energy use and reduced maintenance compared with brushed designs, enabling longer runtime per battery charge. The lightweight construction and compact form factor improve handling in confined spaces and overhead applications. Its aluminum housing increases mechanical resilience and helps manage heat during intensive operation, while the 1/2" drive supports common fastening accessories for automotive, construction and maintenance work.

How to use

Fit a compatible 1/2" socket to the drive and insert a charged 18 V battery according to the manufacturer’s instructions. Select the appropriate speed or torque setting if available, position the socket squarely on the fastener, and apply steady pressure while engaging the trigger. For fastening, run the wrench until the fastener is seated and then switch to a controlled setting for final tightening if required. For loosening, use gradual trigger control to break the initial torque and then increase power as needed. Always remove the battery before changing accessories or performing maintenance.

Recommendations

Use impact-rated sockets and accessories with the 1/2" drive to avoid damage. Inspect fasteners for thread condition before applying high torque. Wear appropriate personal protective equipment, including eye and hearing protection, when operating the tool. Follow the battery manufacturer's guidance for charging and storage to maintain performance and battery life.
