Thsakzo Motorcycle Chain Breaker & Rivet Tool Kit, 15-Piece Fits #25–630, Compact Case

Thsakzo 15-piece chain breaker and rivet tool kit is a portable, all-in-one solution for splitting, removing, and reconnecting motorcycle, ATV, dirt bike, and bicycle chains from sizes #25 to #630.

This compact kit brings workshop-style chain service to your garage or roadside repairs. The set combines a precision-threaded main body, multiple pin sizes, replacement press plates, a lever handle and a molded carry case so you can size, press, and rivet links without improvising or visiting a shop. Engineering choices like reduced thread clearance and centered drive pins reduce the risk of side-plate damage and make pin removal and reinstallation straighter and more reliable.

How does the kit handle different chain sizes?

The kit includes three interchangeable pin sizes (2.2mm, 2.9mm, 3.8mm) and two press plates to match various chain pitches and link types. The design accommodates a broad compatibility range—#25 up through #630—so one toolkit covers small bicycle chains and large motorcycle drive chains.

• Three pin diameters to fit common chain pitches.
• Two press plates for different link profiles and riveting needs.
• Molded case keeps adapters sorted for quick selection.

What makes the tool accurate and safe to use?

Precision threads in the tool body and drive screw minimize lateral play, keeping the driving pin concentric with the chain pin. Proper alignment prevents bending the replacement pin or deforming side plates when pressing out or in, and a step-by-step pin-protrusion recommendation reduces breakage risk under load.

• Reduced thread clearance for steadier pin travel and centered pressure.
• Recommended 0.2" (5mm) pin protrusion prevents over-stress on pins.
• Spring and assembly guide for consistent, repeatable setup.

How do I use the Thsakzo chain breaker for removal and riveting?

Remove the hex bolt, slide the spring over the selected pin, and insert the assembly into the hollow threaded rod. Reinstall the hex bolt and turn until the pin protrudes about 0.2" (5mm); position the chain so the driven pin aligns with the chain pin, then tighten the bolt gradually to press the pin out or rivet it back in.

• Set pin protrusion to ~0.2" (5mm) before applying pressure.
• Align chain and drive pin to avoid side-plate contact or bending.
• Use the lever handle for added mechanical advantage when needed.

What comes in the 15-piece kit and why is it useful?

The kit bundles the main body, a handle, a lever for added leverage, a spring, two press plates and three pin sizes, all organized in a blow-molded carry case. That combination gives you the parts to tackle most on- and off-vehicle chain projects, from cutting links to rejoining with a rivet.

• Complete set of tools and adapters for cutting and riveting chains.
• Blow-molded case protects and organizes components for field use.
• Affordable alternative to professional shop visits for routine chain work.

Who is this for? If you maintain motorcycles, ATVs, dirt bikes or bicycles and want a single, portable tool to cut and reconnect drive chains, the Thsakzo 15-piece chain breaker kit offers a practical balance of precision and value. It's suited to home mechanics, track-day riders, trail riders and anyone who prefers to service chains themselves without costly shop labor. Follow the included setup steps and pin-protrusion guidance to get consistent results and reduce the chance of damaging links during service.
