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

It came quickly, was exactly what I ordered, seems to work as I need it to.

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

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.

The item did what it is intended to do but the press pin was only good for one try.

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

Works great, spring loaded handle for easy insertion of chain into tool. Doesn’t ruin links if you’re careful.

Cheap quality and not very user friendly but it gets the job done. If I could go back I’d spend the few extra bucks on a nicer one

Only allows griping the chain from inside of links, rather than outside, which means user can only push pin out on side of chain at a time rather than pushing pin all the way out of the chain in one operation.

WorKS very easily to remove links from #60 HD snow blower chain. Good quality and price. This is a tool not often needed but indispensable when you do need to repair a chain..

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.
