FAQs
How do I change the speed settings?
The TEENO impact wrench features a variable speed trigger. Squeeze the trigger lightly for lower speeds and pull it further for higher speeds. There are also typically button controls near the trigger or on the tool body to set distinct speed ranges, often indicated by "1" and "2" or "Low" and "High".
What is the torque rating?
This impact wrench provides two torque settings: 180 Nm and 320 Nm.
How long do the batteries last?
With two 3.0Ah batteries and a brushless motor, you can expect extended run time, potentially up to 50% more than brushed motors. Actual runtime depends on the application's intensity and duration.
Can I use any 1/2 inch sockets with this wrench?
Yes, it uses a standard 1/2 inch square drive, making it compatible with most common 1/2 inch impact sockets. Always use impact-rated sockets for safety and durability.

The TEENO 20V Brushless Lithium-Ion Impact Wrench comes with a 24-month warranty.
