What is the primary function of a chain breaker?

The primary function of a chain breaker is to push out the pins in a chain link. This tool is specifically designed to facilitate the disassembly of chain links without damaging the components. By using a chain breaker, you can remove or replace links as needed, which is essential for repairs, adjustments, or maintenance tasks in various mechanical applications.

When you need to shorten a chain or perform maintenance, simply cutting the chain or snapping the links would create potential issues, such as leaving sharp edges or ruining the integrity of the remaining links. The chain breaker, on the other hand, safely enables the removal of a pin, allowing for a clean separation of the chain links, which maintains their usability for reassembly or adjustment.
