Does anyone know a source for chain tools for #25 chain? Our team has been getting along with a bicycle chain tool style one for a while, but we broke it for good recently. There are many tools online for bicycle chain, but we haven’t been able to find any that specifically fit #25 chain. Anyone know where we can find one?
One chain tool that I know many teams recommend is the Easy-Grip Roller Chain Breaker from McMaster-Carr. That is what our team used this year and it worked well.
You want the one for chain sizes 25-60. Part #6051K15
Assuming that you are talking about a chain breaker, id like to advise you against it, from my experience with 25 chain, chain breakers tend to ruin the surrounding links, however an effective method that you could try is with a Dremel and center punch, What we do, is use the dremel to grind away the tip of the pin until just past the surface of the link itself, once its at that point, take the center punch, and align it with the pin, and gently knock it out with the center punch, and voila you then have separate pieces of chain, and assuming it is done right, they will not be damaged:)…
however if you do wish to use a chain breaker instead here are a few links that can help you out

We’ve been using the easy grip roller chain breaker mentioned above on #25 chain and haven’t had any problems damaging links.
If you use a chain breaker not meant to be used for #25 chain you will damage the links. If it is made to be used with #25 chain and it is damaging link I highly doubt that the company would still be selling it.

I don’t work with #25, but on #35, I just grind off the end of the pins on a bench grinder and gently tap out the link being removed. I grind out part of the sideplate, so it comes out quite easily. It takes very little time, though it cah get a bit hot to hold onto 
Here’s a breaker made in U.S.A. http://www.pattontool.com/25thru60.htm
We also use the “Easy-Grip Roller Chain Breaker” and have had no problems with it. It takes less than 30 seconds to break a chain: Punch one side, punch the other and then twist the chain - Done
I have used the easy grip chain breaker for a good 6 years and NEVER had a problem. I have used it on 25 and 35

If you’re looking for something like a chain puller, here’s what we did: We bought a chain puller made for 35 chain, then took a dremel to the tips in order for it to fit between links of 25 chain. It’s been working great for us for years.
As for breakers, we’re using one made for 35 chain and bigger… and have never broken a link.
