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.

Made the resizing of the chain so much easier .

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 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.

It’s works .. Does the job...

It works. Half decent chain breaker. The tips are soft but thankfully it comes with an extra. I would buy it again. I just think its great. I popped two links on some older 420 chain and mushroomed out the whole tip if of the breaker. I managed to file it down and there is a spare it was just kind of disappointing.

I thought I was going to have to grind the pin down a little, but this thing drove it out well, I cranked it with pretty serious force and it held good.

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

Exactly what it says it is

Worked pretty well but I found that it didn’t punch the chain all the way through it basically just breaks it free because I had to Finnish it off with a punch.
