The inertia hammer, also known as an inertia puller or kinetic hammer, is a tool used to remove stubborn or stuck components in machinery, equipment or vehicles. It is especially useful when it comes to loosening screws, pins, bearings, gears or other parts that are firmly stuck due to corrosion, oxidation or dirt build-up.

The operation of the inertia hammer is based on the principle of inertia. It consists of a handle or handle at the end of which is a heavy mass that can slide freely. When the inertia hammer is used, the operator applies a quick, abrupt force to the handle, causing the internal mass to move rapidly forward and then come to an abrupt stop due to the resistance of the clamped part.

This sudden movement of the mass creates a kinetic impulse that is transmitted to the part, helping to loosen it.

When using an inertia hammer, it is important to follow certain safety precautions. Be sure to wear goggles to protect your eyes from any loose debris or fragments. Also, choose the appropriate size inertia hammer for the job at hand, as different sizes are available to suit different needs.

Overall, the Inertial hammer is a valuable tool for dismantling stuck or difficult-to-remove parts. It leverages the physics of inertia to create enough momentum to drop these parts without causing significant damage to them.
