Seesii 3/8" Cordless Impact Wrench WH450 — 21V Brushless, 330 ft‑lbs Torque, 4.0Ah Battery & LED

The Seesii WH450 is a compact 3/8" cordless impact wrench delivering up to 330 ft‑lbs (450 N·m) of torque with a brushless motor and a 4.0Ah rechargeable battery for fast, portable light‑duty work.

The WH450 combines higher torque in a shorter body with a brushless 21V motor, two speed settings, and a built‑in LED so you can reach nuts and bolts in cramped, low‑light places. The kit includes a 4.0Ah battery, fast charger, four CR‑V sockets (14/17/19/21mm), and a carrying case, making it a ready‑to‑go option for automotive, home maintenance, and DIY jobs.

How much power and speed does the WH450 deliver?

This compact impact wrench uses a brushless 21V motor to reach up to 450 N·m (330 ft‑lbs) of torque and as much as 3000 RPM in high mode. Two speed modes let you switch between controlled fastening and high‑speed removal; the brushless design improves runtime and motor life.

• Peak torque: 450 N·m (330 ft‑lbs)
• Max speed: up to 3000 RPM
• Two speed modes for precision or power
• Brushless motor for longer runtime and durability

Will this tool handle tight spaces and dark work areas?

Yes — the WH450 has a shortened 5.11‑inch body and weighs about 3.5 lbs, so it gets into narrow, deep locations easier than larger impact guns. The integrated LED illuminates work areas for improved visibility when working under cars or inside engine bays.

• Compact length: 5.11 inches for increased accessibility
• Lightweight: roughly 3.5 lbs for reduced fatigue
• Built‑in LED light to brighten dark cavities

How does the WH450 help with safety and control?

The wrench offers forward and reverse control plus a brake‑stop feature that slows and stops the tool once a fastener is freed so sockets or nuts don’t fly off. Combined with an ergonomically rubberized grip and balanced weight, it gives stable handling for repetitive tasks.

• Forward/reverse switch for controlled loosening and tightening
• Brake‑stop reduces speed after loosening to keep hardware in place
• Rubberized ergonomic grip for comfort during extended use

What comes in the kit and how long does the battery last?

The WH450 kit ships with one 4.0Ah battery, a fast desktop charger with LED power indicator, four CR‑V sockets (14, 17, 19, 21mm), and a sturdy carrying case. The larger 4.0Ah pack provides roughly 50% more runtime than typical 2.0Ah batteries, reducing downtime for frequent jobs.

• Includes: WH450 impact wrench, 4.0Ah battery, fast charger, 4 sockets, carrying case
• Battery: 4.0Ah for extended run time versus 2.0Ah cells
• Charger: desktop fast charger with LED status indicator

This Seesii WH450 is designed for light‑to‑medium tasks where reach, portability, and ease of use matter. It suits DIYers who change tires, hobbyists doing automotive repairs, homeowners tackling maintenance, and professionals who need a compact backup impact gun. If you need high torque from a small frame with reliable battery life and essential accessories included, this kit is a practical, portable choice.
