What is the difference between manual and pneumatic impact wrenches?

Manual and pneumatic impact drivers are both important tools in the world of DIY and professional workshops, but they have some key differences in terms of operation, performance, and application.

Manual impact drivers:

• They require physical force. By striking the rear end of the impact driver with a hammer, a rotational movement is generated that loosens or tightens the screw.
• Manual impact drivers are generally simple in construction and therefore very robust.
• They do not require a power supply or compressed air, making them highly versatile.

Pneumatic impact drivers:

• Due to their air supply, pneumatic impact drivers generally have higher power than manual models and are capable of loosening even seized screws.
• They are mainly found in professional workshops, as they require a constant air supply, usually provided by a compressor.
• Pneumatic impact drivers can be used for longer periods without requiring much effort from the user.

The choice between a manual and a pneumatic impact driver should be based on the intended application, the available working environment, and the specific requirements of the task at hand.
