Key Features

• Exceptional Torque Performance: Delivers up to 360 ft-lbs (488 N.m) of tightening force and can loosen bolts up to 503 ft-lbs (682 N.m), making it ideal for heavy-duty applications such as tire changes, engine maintenance, and structural assembly.
• 3-Speed Precision Control: Features three adjustable speed settings—258, 295, and 360 ft-lbs—paired with a variable speed trigger that provides up to 20% more control over power delivery. This allows for optimized performance across different fastener types and materials, from delicate assemblies to high-resistance bolts.
• Advanced Brushless Motor Technology: Equipped with an all-copper motor that generates 30% more stable power output and offers 50% longer runtime than conventional brushed motors. This results in sustained performance during prolonged use without significant drop-offs in efficiency.
• Fast Directional Switching: Easily switch between forward and reverse operation in just 0.5 seconds using a single-button mechanism. The advanced reverse technology reduces mechanical stress by 15%, protecting both the tool and the workpiece during tough loosening jobs.
• Integrated LED Illumination: A built-in LED light enhances visibility in dimly lit or confined spaces such as under vehicles, inside engines, or within machinery housings, ensuring accurate and safe operation regardless of ambient lighting conditions.
• Versatile Compatibility: Designed to work effectively with over 90% of common clamping structures, dismounting tasks, installations, and automotive repairs. Its broad application range makes it suitable for construction, industrial maintenance, fleet servicing, and home improvement projects.
• Comprehensive Package Inclusion: Comes fully equipped with a 4.0Ah lithium-ion battery, a fast charger, four durable impact sockets (3/8″ (10MM), 1/2″ (13MM), 3/4″ (19MM), 13/16″ (21MM)), two cylindrical mounting pins, two O-rings for secure attachment, a belt hook for hands-free carry, and a heavy-duty nylon carrying bag for organized storage and portability.
