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

The chain breaker for 415 size chain is a device that pushes out the pins holding the links together. This device will only partially push the PIN out of its link nest, therefore you need to use a small punch to completely extract the pin to separate the links. It doesnt work as well as the tool for bicycle chain.

Use for go cart chain replacement. Worked great. Easy to use. Pretty good quality

Very easy to use, great value.

It does its job, gives me the chain length I need.

Works perfectly, cut a few chains for my bike. Glad they included extra tip in the package too.

I had a drive chain on a minivan tailgate that had broken. My choices were to replace the broken chain or spend $300 with the dealer to get the part including the chain. The area to work was tight, difficult to see and the chain quite small. I was able to get this into the spot and complete the job. I have only used it for the one job, but my son will be using in on bicycle chains, Im sure. But I cant speak to durability yet.

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.

i only had to use it twice so far... and its been a non issue and worked every time.

Buy this one.

After a few times using the link extractor. I realized that its as usual Chinese made products are of inferior quality. I really am disappointed with mad in China. I love the prices but if I have to buy ten of them to fix something its just a headache. The vendors are very good about replacing the product but its not their fault for badly made products. Im sure they are greatly disappointed too. Especially since its their fellow countrymen making the product. Dont get me wrong I have spent a ton of money online buying Chinese products and a ton of money at the restaurants buying food.. Lol OMG if they made their products like they do their food it would be out if this world. You know what they say when you buy a used car buyer beware. Same applies here. Cheaper is just that you get what you paid for.
