A slide hammer, also known as a dent puller, is a tool used to remove dents or other damages from a vehicle's bodywork. The tool consists of a long metal rod or shaft with a handle at one end and a weighted sliding hammer at the other.

To use a slide hammer, first, attach a dent puller or other attachment to the weighted end of the tool. The attachment will be used to grip the damaged area of the vehicle. Next, place the attachment onto the damaged area and use the slide hammer to apply force and pull the dent out.

As the slide hammer is pulled back, the weight on the end of the tool creates momentum that is transferred to the attachment, providing a pulling force that can straighten out the metal. This process may need to be repeated several times until the dent is fully removed.
