AZSSMUK Roller Chain Breaker Detacher Tool for Size #25#35#41#40#50#60 415H,428H, 520,530 Motorcycle Bicycle Go Kart Chains Replacement

Exactly what I needed. Shipping was fast, item worked perfectly, and is good quality. Thanks!

Sturdy construction, no chain

worked great. used to repair drive chain on craftsmans tiller transmission.

It is work ok on the standard 520 chain, however, it’s difficult to remove the heavy duty type of chain. Maybe should buy different size of the breaker.

Done what it is supposed to do

Its not big enough to actually fully detach the chain on a #40 dollar chain. It can loosen the pins so you can get it apart, but if youre trying to completely remove the pin between the links, its not going to work, the pin isnt long enough to push it all the way out.

I bought this chain breaker probably about 4 years ago and I am a motorcycle mechanic and use it pretty much on the daily on multiple projects and it hasnt failed me yet and still going great value didnt have to pay that much for it but for something for that value to work this long I back at 100% very satisfied with it and still going.

If you are lucky.

Specialty tools are typically expensive, for the price I was worried. Broke 2 50 roller chains and 2 30 roller chains with ease. The pin didnt break or mushroom like people reviewed. They must not know what they are doing. It does include an extra pin also. Worth the money and will get the job done.

I needed this for an FTC robotics project which has #25 chain. We had this included aluminum thing that hardly worked. So I bought this. It looks a lot like the USA made breaker from McMaster which cost 4 times the price. It looks and feels solid and comes in a box which implies precision engineering, but its not precision engineered at all. The cam holes are very sloppy so that the gripper teeth neither center the chain nor after 2 or 3 uses are even able to hold on to it tight enough while pushing the pin down. So the pin neither stays center and Im not entirely sure that this would fit in the #25 chain anyhow -- the teeth are just too large. It did break the chain multiple times, to the point that they werent remotely usable afterwards. Im now taking a recommendation from my robotics forum and bought a DarkSoul chainbreaker.
