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

I needed it to shorten a chain for a go kart project. It was a little tricky to use at first but once I got it figured out it worked quite well.

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.

This tool takes the headache out of guest work if you dont know the correct size. Order chain for tow behind 15 to 25 years old spike drop seeds spreads and did not have the correct size or link. I ordered the chain about 3 to 4 inches longer to be sure work great

Very easy to use, great value.

Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses this chain breaker will not break bike Cain or motorized bike chain or a bicycle chain.

Great product, actually was sold a small aggravating one from local motorcycle shop for $10 more than this one. Returned it and waited on this one to ship to me, glad I did, so much easier and includes replacement tips.

I wrote a good review, but upon further using this tool, i found out why it didnt work properly, its not for a # 40 chain like i ordered, this one was for a #25, #60. Too late to do anything about it, but the tool itself is a good product.

I used this to break a # 41 chain, was easy to use and had no problems with it.

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.

This item works. But, it is easier to simply use a file and punch.
