Review and analysis

Impact wrenches are powerful cordless tools designed to deliver high torque for driving and removing fasteners. They utilize compressed air or batteries to generate rotational impacts that can loosen even the most stubborn bolts and nuts. Seesii is a relatively new player in the power tool market that aims to deliver professional-grade impact wrenches at an affordable price point.

The Seesii WH760 is their flagship 1000Nm cordless impact wrench. It promises best-in-class torque along with brushless motor technology for improved performance and battery life. In this review, we'll take an in-depth look at the specs, features and real-world performance of the Seesii WH760 to see if it lives up to its promises. A high-torque cordless impact wrench can be an invaluable addition to any automotive or construction toolkit when heavy-duty driving and loosening of bolts is required. But with so many models on the market, it's important to understand the key factors that separate the good from the great.


The Seesii WH760 cordless impact wrench is a powerful tool designed for automotive and truck service. It offers impressive specs:

  • Power: Brushless motor provides 1000 Nm (738 ft-lb) of max torque and 2600 RPM no load speed for heavy duty applications
  • Torque Settings: 4 torque settings from 300-1000 Nm for precision control
  • Motor: Brushless motor for increased efficiency, runtime and durability
  • Battery: Includes (2) 4.0 Ah 20V MAX lithium-ion batteries for extended runtime
  • Charger: Rapid charger fully charges batteries in 60 minutes or less
  • Anvil: 1/2" anvil with pin detent for quick socket changes
  • Impacts Per Charge: Up to 750 impacts per charge
  • Drive Size: 1/2" drive

With a high-powered brushless motor, 1000 Nm of torque, and large capacity batteries, the Seesii WH760 has the muscle for lug nuts, suspension components, and other stubborn bolts on cars, trucks, machinery, and equipment. The 4 torque settings allow for fine control when needed.

For those looking for a slightly less powerful but still high performing cordless impact wrench, the SeeSii WH700 is an excellent option. With a max torque of 479 ft-lbs, it has plenty of power for most automotive jobs. And it comes bundled with 2 large 4.0Ah batteries, 6 sockets, a drill bit set, and screws - making it a complete kit ready for your garage. The WH700's brushless motor boosts runtime, torque, and durability compared to brushed motors. It's ideal for lug nuts, brake calipers, suspension components, and other stubborn bolts. Change sockets quickly with the 1/2" anvil with detent pin. With up to 700 impacts per charge, you can power through many jobs before needing to recharge. Weighing only 4.4 lbs with battery, the WH700 offers impressive power in a lightweight, ergonomic design. This cordless impact wrench is a versatile addition for any auto mechanic or DIYer.

When shopping for a new cordless impact wrench, key factors to consider are torque, motor type, battery capacity, weight, anvil size, impacts per charge, and included accessories. Both the Seesii WH760 and WH700 deliver strong performance specs to handle automotive jobs. Going with a brushless motor model like these will provide benefits over brushed motors. And having multiple large capacity batteries ensures you can work longer before recharging. For heavy duty bolts, the WH760's 1000 Nm max torque has the brute strength needed. Yet the WH700 still packs substantial power in a lighter weight design. Review the torque requirements of your specific applications to choose the best option. But you can count on Seesii cordless impact wrenches to provide the muscle and runtime to power through tough jobs.


The Seesii WH760 impact wrench features a compact and lightweight design that makes it easy to maneuver and reduces user fatigue. It weighs only 5.4 lbs with the battery installed, making it one of the lightest 1000Nm impact wrenches on the market.

The tool itself is made from high-strength composite materials that are durable yet lightweight. It has an ergonomic overmolded rubber grip that provides a secure and comfortable hold. The grip has textured areas that help prevent slippage even when your hands are oily or wet.

At only 7.4 inches long, the WH760 is a good size for tight spaces like engine bays. It has a low profile head that gives you improved visibility and access in confined areas. The short length doesn't compromise performance - it still delivers an impressive 1000Nm of maximum torque.

Overall, the thoughtful design focuses on reducing fatigue and giving users more control and access. The compact size paired with the ergonomic grip makes the WH760 easy to handle and comfortable to use, even for extended periods.

In addition to the compact and ergonomic design, the WH760 also offers excellent performance. It delivers 1000Nm of max torque, providing the power needed for demanding automotive and industrial applications. The brushless motor is efficient and maintains torque output even at low battery levels. Variable speed and torque settings allow users to customize the tool's output for the task at hand.

Seesii also offers the WH550 cordless impact wrench, which provides similar performance benefits in a 1/2" drive size. The WH550 generates an impressive 550Nm of max torque from its compact brushless motor. It comes as a kit with a 4.0Ah battery, charger, and 4 sockets to get you started.

With 405 ft-lbs of nut busting torque, the WH550 makes quick work of stubborn bolts and fasteners. The integrated LED light illuminates dark work areas. Like the WH760, it has variable speed/torque settings and an ergonomic grip for comfort. At only 5.7 inches long, the WH550 can reach fasteners in tight spaces.

Both the Seesii WH760 and WH550 demonstrate how a thoughtful, compact design can reduce fatigue and improve access without sacrificing power and performance. Their smart size, ergonomic shape, and brushless motors make them ideal choices for automotive service, industrial maintenance, and construction applications.


The Seesii WH760 impact wrench delivers impressive performance that rivals professional-grade tools. Its powerful brushless motor provides up to 1000Nm or 738ft-lb of maximum torque, making it capable of handling even the most stubborn bolts and nuts.

The speed tops out at 2500rpm which is adequate for most automotive and mechanical tasks. While not the fastest impact wrench available, the WH760 strikes a good balance between speed and torque. It has enough grunt to remove lug nuts and suspension components without issue.

When it comes to runtime, the dual 4.0Ah batteries give you plenty of juice before needing a recharge. Expect around 150-200 bolts removed per full battery. Runtime can vary depending on the task, but you'll get at least a couple hours of continuous use per battery.

One area where the WH760 excels is accuracy. The variable speed trigger gives you precise control over the torque output. This allows you to dial in just the right amount of power for the job without overtightening or stripping bolts. The WH760 also has 4 torque settings that further improve accuracy for specific applications.

Overall, the performance of the Seesii WH760 impact wrench is very solid. It has the torque, speed, runtime, and accuracy for most DIY automotive and home improvement projects. The brushless motor provides pro-level power in a compact and affordable package.


The WH760 impact wrench comes with several useful features that improve the functionality and user experience.

LED Light

One handy feature is the built-in LED light located right above the trigger handle. This light illuminates the work area to help you see when working in dimly lit spaces or at night. The light automatically turns on when the trigger is pulled.

Battery Gauge

The tool has a battery fuel gauge that indicates the remaining battery life. This allows you to see at a glance how much runtime is left before you need to recharge. The fuel gauge is especially helpful for avoiding unexpectedly running out of juice mid-project.

Sockets Included

The WH760 includes 5 different sized sockets—10mm, 13mm, 17mm, 19mm, and 21mm. Having this assortment of commonly used socket sizes means you can tackle a variety of bolts and nuts right out of the box. The included case provides organized storage for the sockets when not in use.

Noise Level

The Seesii WH760 impact wrench operates at a noise level of 89 dB, which is typical for a cordless impact wrench of this size and power output. The brushless motor helps reduce noise compared to brushed motors, but it is still quite loud during operation.

89 dB is comparable to the noise level of a gas lawnmower, so hearing protection is highly recommended when using this tool for extended periods. The noise can be startling at first, especially in an enclosed space like a garage. But users tend to acclimate to the sound over time.

Some users may find the WH760 slightly quieter than comparable models from other brands. But most 1/2" impact wrenches in this torque range produce similar noise levels around 85-90 dB. The noise is a byproduct of the tool's high torque and rapid impacts. While not ideal, it's an acceptable tradeoff for the time savings and convenience provided by a powerful cordless impact.

Those sensitive to noise should consider lower-powered impact drivers or ratchets, or look for models with sound dampening technologies if lower noise levels are a priority. But the noise level of the Seesii WH760 is typical and should not deter most users given its other benefits. Ear protection is recommended for extended use.


The Seesii WH760 impact wrench comes with a few handy accessories to get you started.

Batteries and Charger

The impact wrench includes two 4.0Ah lithium-ion batteries that provide long runtime. With the fast charger, the batteries can be fully recharged in about an hour. Additional batteries can be purchased separately for extended use or to always have a spare charged and ready.


Five different sized impact sockets are included for common fastener sizes. The set includes 17mm, 19mm, 21mm, 23mm, and 24mm sizes to cover lug nuts and bolts for most automotive applications. More socket adapters and sizes can also be bought separately for increased versatility.

Storage Case

A sturdy plastic carrying case with custom foam compartments allows you to safely store and transport the impact wrench, batteries, and included sockets. The case keeps everything neatly organized in one place.


Proper maintenance is key to ensuring your Impact Wrench performs optimally for years to come. Here are some tips:

Cleaning - Over time, dust and debris can build up in the motor housing and gearbox. Use compressed air to blow out any particles. You can also use a soft brush and cloth to gently wipe down the housing and anvil. Avoid submerging the wrench in liquids or using harsh cleaners.

Lubricating - Regularly apply a lightweight machine oil to the anvil and any moving parts. This prevents corrosion and keeps components operating smoothly. Avoid over-oiling. Refer to the manual for lubrication points and frequency.

Brush Replacement - The motor brushes will gradually wear down with use. Check them occasionally for significant wear. When they reach the minimum length specified in the manual, replace them with identical brushes from the manufacturer. Use care when accessing the brushes to avoid damaging connections.
