The patented ANSI 40 Die Set cuts #40 ANSI chain 1/2" (0.500) pitch single strand roller chain. Smith Craft Products die sets for each chain size are easily interchangeable; changing from one die set to another can be accomplished in a few seconds!
We have been using smithcraft products for at least 8 years at least it is a big help in our manufacturing process we just bought a 40 die set very easy to switch from 1 set to the other I would recommend buying the backing plate with any set you buy. The first one I bought I had to drill and tap the die myself but now they come ready to install from the factory if you cut a lot of chain this is the way to go just make sure you clean out the track where you break the chain as a link left there will break the pins in the die set they have repair sets and spare parts readily available as you can tell I’m a very satisfied customer thank you smithcraft
