The BlueSpot Motor Cycle Chain Breaker is used for the repair, splitting and riveting of new and old motorbike chains. The Chain Breaker is made from heat-treated, hardened steel and can be used with chain pitches from 35 to 630. Heavy-duty chains will require the pinheads to be ground off prior to breaking. Four push pin sizes for various chain pitches. The square design can easily be bolted to a work surface, fastened in a vice, or held by hand. Handle winds push pins to remove rivets from chain links for alteration and the same action is used to replace the rivets once desired length is obtained with the use of the adaptor press plate and riveting and pin anvil. Rivets and other consumables are sold separately. The kit comes in a handy carrying case for quick and easy storage
