Koch 7725010 Roller Chain Breaker, 25 to #60

Would this work on a 415 chain for a 66cc motor?

I need a replacement tip. Where do i get it? I tried pushing a pin out on a 520 chain and the tip crumbled.

Can this break #35 chain? Or is the tip too big?

Those people who have mentioned this doesn't work for #25 chain as used in tetrix ftc robotics etc, what solution would you recommend?
