If you broke the chain breaker tip for the 520 and 525 chains in your Motion Pro Chain Kit then this is what you need. Will not fit the standard Motion Pro Chain Breaker that is sold alone. Will only fit in the Chain Kit.

The tool works well, if at home always use a grinder to remove pin head, in the field no grinder the tool push pin stress very hard to push or break link apart, and very likely to break. Nice to be able to have a spare push pin. Thanks KTM
