## Caption

Inside, a spring-loaded hammer and anvil mechanism rapidly stores and releases energy. As resistance increases (like driving a long screw into dense wood), the motor compresses a spring. Once it reaches a threshold, the spring releases—spinning a hammer that strikes an anvil connected to the bit.

This creates high-torque rotational impacts in quick bursts instead of continuous force. The result:

* More torque with less strain on your wrist
* Less cam-out (stripping screws)
* Better performance in tough materials

It’s not just stronger—it’s smarter about how it delivers force.
