KZNANZNDetacher Breaker Cutter Fit for #25#35#41#40#50#60 415H,428H, 520,530 Roller Chain Bicycle Go Kart ATV Chains Replacement (Black)

Easy installation, the value is best from anywhere , durable so far It’s been man handled, I’m in a apartment and it works great even comes with a spare tooth

I got this chain breaker yesterday and today I shortened several 420 chains. The breaker worked perfectly. I see some complaints but I really believe they are coming from first time or inexperienced users.

Eh, the item sort of works. I’ve used it a few times to pop out a link or 2 on chains but it’s weird how it aligns itself. It doesn’t seem to properly self center the portion that pops out the pin so you need to loosen and realign a few times. Does it work, yes, always. For the price , I didn’t return it

During a pre-trip inspection I noticed my chain drive for my slide looked weird. A link had metal fatigue and started to come apart. This tool was perfect. The clamp was solid, and it pushed the pins out so I could install a master link with clip.This is now a permanent onboard tool for when I go camping. It would have been very bad if this link had broken during a trip.

Break things and put them back together with ease

Absolutely terrible does not even break chain all the way, then after we we figured out how to push the pen all the way it broke after using it about 5 times. Do not buy.

As others state, pin mushrooms and deforms. My first one shattered and the 2nd one broke, but stuck together enough to finish the two chains. Will not be usable in the future. Consider pins consumable.Handles could be a little longer for more torque, will suck for the young 20 somethings doing their first chain.For the price it's hard to beat, but consider it one-time use overall.

This tool fit #40 roller chain -- the jaws clamped the chain under an inner plate, the jaws were automatically centered around the roller because of their V-shape (and thus the sharp press pin was centered over the chain's bearing pin). After turning the handle clockwise so that the first bearing pin started moving downward, I retracted the tool's press pin and then mounted it on the inner plate's neighboring bearing pin. After pressing that neighboring pin a similar distance down, I switched back to the first pin and pressed it completely through the outer plate. And then I switched to the neighboring pin and pressed it completely through as well. Going back and forth a couple of times between the two pins of an inner plate was the key to removing the chain without bending it. Excellent tool for the price for DIY repair of an Eagle 1000 slide gate operator.
