Chain Breaker with Folding Handle

Brief Overview

This chain breaker is a straightforward, professional-grade tool designed for breaking and servicing motorcycle and automotive chains in the 420, 428, 520, 525, and 530 pitch range. Built with a robust C-shaped jaw assembly and threaded drive mechanism, it delivers reliable performance across a wide spectrum of common chain sizes. The folding handle design makes it ideal for workshop storage without taking up bench space. For shops needing a complete chain service solution, consider pairing this with a combination chain breaker and riveting system to handle both breaking and chain reassembly in a single workflow.

  • C-Shaped Jaw Design: Holds chain securely during operation, preventing lateral movement
  • Threaded Drive Mechanism: Controlled force application via hex-headed adjustment screw with accompanying hex key
  • Folding Handle: Black foam-padded lever pivots away for compact storage
  • Durable Construction: Stamped steel lever with riveted assembly; dark metal jaw construction resists wear
