Useful tool
The DYC chain breaker tool is a strong and simple tool that works exactly as it should. The metal body feels solid and heavy, not cheap or flimsy, and the threads on the press screw are smooth with no binding. It lines up perfectly on 420 through 530 size chains and pushes the pins out cleanly without bending or slipping. The handle gives good leverage, and the tip stayed straight even after a few stubborn links. It’s compact enough to carry in a toolbox but sturdy enough for regular shop use. For the price this tool is excellent quality and makes breaking and resizing chains quick and easy. Five stars for strength, precision, and value.

Simple to use and it works.
Excellent tool for breaking light gauge motorcycle chain, seems sturdy, and so far has broken a chain three times successfully. It does take a great deal of hand strength, but for the price it's an awesome addition to the tool kit.

Do not buy!
Junk. I used it once on a dirt bike chain and it was broken after that. The handle to turn it bent easily and the tip that pushes the chain pin through, broke in half. I would post a picture of it but I sent flying through the air into the abyss. Buy a different product.

Easy to use, Works Perfect, Great Price
We used it on a HD-428 chain several times to get the right length. Works flawless! Easy to use. Great price!

Worked good
Took a lot more force than I would've thought but it worked. I just started it turned it a bit that backed it out like 3 or 4 times to make sure it was flush and not crooked. It felt like the tool would break but it didn't just make sure its not crooked on the chain. I prefer using this over grinding the chain off any day. For the price it worked as intended.

Great tool for the price
Good size, i found the tip of the breaker a little too big for one of my chains but the reason for the 3 stars is the quality. The tip broke after breaking 2 pins. Other than that, it’s a great tool for the price but if you’re going to be breaking heavy duty chains, you’re better off spending an extra 15 and getting a proper chains breaker kit.
