20V 430n. M Brushless Impact Wrench 1/2" Cordless Heavy Duty Tool Kit

The CW-20B delivers a maximum torque of 430N.m, powered by a high-efficiency brushless motor. This makes it more than capable of loosening and tightening heavy-duty bolts and lug nuts in automotive, construction, and industrial applications. The 2-speed control (0-1900/0-2400 RPM) allows you to match torque and speed to the task.

This impact wrench features a standard 1/2-inch (12.7mm) square drive, which is the most common size for automotive and general-purpose impact sockets. It is compatible with all standard 1/2" impact-rated sockets, extensions, and adapters from any brand.

Yes, the CW-20B is equipped with a brushless DC motor. Compared to brushed motors, the brushless design delivers higher efficiency (less energy wasted as heat), longer motor lifespan with zero carbon brush replacement, more compact size, and cooler running temperatures during continuous heavy-duty use. You get more work done per battery charge.

The tool comes with a 20V (Max 21V) Li-Ion battery pack available in 3.0Ah or 4.0Ah capacities. The 4.0Ah version provides extended runtime for professional all-day use. The battery features zero memory effect and supports partial charging without capacity loss. A full charge takes approximately 3-4 hours with the included fast charger (100-240V AC universal input). The battery is fully cross-compatible with our entire 20V tool family, including angle grinders, rotary hammers, chainsaws, work li

The reverse auto-stop function automatically stops the tool when a nut or bolt is loosened in reverse mode. This prevents the fastener from spinning off completely and falling, which is especially useful when working at heights, over water, or in tight engine bays. The H/L torque button on the base allows you to switch between high and low torque modes within the auto-stop function for different fastener sizes.
