**Limited supply of Made in USA CB1 Roller Chain breakers available**
The smallest chain breaker we supply is designated by part # CB1. This chain breaker provides customers with the ultimate amount of versatility for roller chains with a pitch ranging from 1/4" (6.35mm) up to 3/4" (19.05mm). Some may know of this breaker size of being the 25 - 60 chain breaker, but it is far more capable than simply breaking ANSI 25 - 60 chain sizes. CB1 Chain Breaker Capabilities:
The CB1 roller chain breaker can also break duplex, triplex, and quad-strand chains, making it the most powerful and versatile hand-held small chain breaker on the market!
CB2 Roller Chain Breaker
**Limited supply of Made in USA CB2 Roller Chain breakers available**
Next size up is the CB2 roller chain breaker, a medium hand-held tool designed for breaking chains with a pitch of 3/4" (19.05mm) up to 1-1/4" (31.75mm). This breaker class is also called a 60 - 100 roller chain breaker, but much like the CB1 above, its capabilities are not limited to ANSI 60, 80, and 100 chains. CB2 Chain Breaker Capabilities:
Like the smaller breaker, the CB2 can break duplex, triplex, and quad-strand chains, unlike most of its inexpensive import replicas.
CB3 Roller Chain Breaker
**Unfortunately, we are out of stock of Made in USA CB3 chain breakers and they have been discontinued by the manufacturer. Please contact us to check availability on globally sourced CB3 breakers.**
The next size chain breaker is the CB3; this mecca of a tool makes breaking even large roller chains easy. Some may know this as the 120 - 160 roller chain breaker, but like our other chain breakers, it is far more capable than just breaking chain sizes 120, 140, and 160. CB3 Chain Breaker Capabilities:
ANSI Roller Chains - #120, #140, #160
ANSI Heavy Roller Chains - #120H, #140H, #160H
ANSI Double Pitch Chains - C2120H, C2160H
Metric Roller Chains - 24B, 28B, 32B
Metric Double Pitch Chains - 224B, 228B, 232B
The CB3 chain breaker can also break duplex, triplex, and quad-strand chains. This is only achievable due to the grade and heat-treatment processes that are done to the breaker. Breaking multi-strand roller chains places more stress on a tool; our CB3 is built with the strength necessary to do this. Please note that if you need a breaker larger than the CB3, we have a Made in Japan CB4 breaker capable of breaking chain sizes 160 - 240!

Clamp the Chain Breaker Onto the rollers of the roller chain.
Note: It is imperative to ensure that the tip of the roller chain breaker and the pin of the roller chain are aligned precisely. If not, you may break the chain breaker tip or be unable to break the roller chain.
Turn the handle clockwise to push the pin and break the rivet of the chain.
The end result of this should look something like the photo below. As you can see, the roller chain rivet has been broken. Some people choose to stop at this step and attempt to push the single pin out. While this may work in some instances, not only is it not recommended, but it can also be tough to do.
Next, you repeat steps one and two on the other pin.
After this step, your chain should look something like the photo below. Both rivets on that chain side are now broken, and you are ready to remove the pin link.
I
If all steps are done correctly, and you have removed your pins, you should have successfully cut/ broken your roller chain.
