Seesii Impact Wrench 665 ft-lbs (900 N.m) 21V Cordless High Torque | Dual Battery Kit & Case

Power and performance in a cordless tool

Meet the Seesii Impact Wrench, engineered to deliver high torque with a brushless motor. It offers 579 ft-lbs of tightening torque and 665 ft-lbs of loosening torque, along with 3300 IPM and 2400 RPM. This powerful combination helps you move through wheel installation and fastener removal more quickly, even when bolts resist or corrosion has set in. The balance of speed and force provides a sense of momentum without sacrificing control, so you can choose the pace that suits the task at hand.

On real-world jobs, you might install a wheel in a few seconds and free a stubborn bolt in minutes. These numbers signal the potential for efficient, less strenuous operation relative to manual wrenches, while still letting you modulate your effort to match the situation.

All-day power with a dual-battery system

The wrench ships with two 21V 4.0Ah lithium batteries to extend runtime for long maintenance sessions or multiple repairs. A 30-minute rapid charge can bring batteries to about 80% capacity, so you can keep working during short breaks without long downtimes. A 3-LED indicator provides at-a-glance battery status for smarter planning.

• Two batteries mean more uptime and less fatigue during continuous work
• Rapid charging minimizes downtime and keeps you productive
• LED status helps you monitor power without guessing

Designed for high-intensity tasks with comfort

The tool uses a 1/2 inch square head to handle substantial torque, making it suitable for truck tires, large mechanical bolts, and other demanding jobs. An ergonomic design with a 16-inch compact body and a 9.3-pound weight offers a balanced grip, while an anti-slip nylon strap lets you hang the tool for quick access. A built-in LED work light ensures visibility in dim work areas.

• Ergonomic, lighter profile supports longer use without fatigue
• Anti-slip grip and thoughtful weight balance improve control
• LED illumination helps you work in garages or on job sites after dark

Durability and smart safety features you can rely on

The Seesii wrench combines tungsten steel and alloy steel parts for strong impact resistance and longevity, while military-grade ABS housing withstands drops. Vibration-dampening construction and a cooling fan help maintain control and temperature under continuous use. Smart protections guard against over-current, over-voltage, overheating, and short circuits, with an auto-stop function to prevent over-tightening and a 10-second auto shutoff to protect the motor.

• Rugged build designed for frequent professional use
• Smart protections promote safer operation on busy days
• Cooling and dampening features help maintain performance

Everything you need in one comprehensive kit

In addition to the impact wrench itself, you get six sockets (14/17/18/19/21/22 mm), dual batteries, a fast charger, a heavy-duty storage case, and a manual. This setup covers common automotive and industrial bolt work, from maintenance bays to remote sites.

Note: While the tool offers strong performance potential based on its specifications, actual results depend on task, technique, and conditions. Use with care and follow safety guidelines to maximize outcomes.

Whether you’re a professional technician or a DIY enthusiast, the Seesii Impact Wrench aims to deliver speed, control, and reliable performance for everyday reliability and situational flexibility.
