You won't be able to cut chipboard with the Sizzlit dies, sorry! They are a low profile die with a cutting edge that's around 1/16th of an inch thick. :( The only Sizzix dies that will cut through chipboard effectively are the larger, steel rule (original) dies. Those dies have a cutting edge that's almost 1/4th of an inch think, to be able to cut through those really thick mediums like chipboard.
I have heard of people cutting "chipboard" with their Sizzlits, but my guess is that it was VERY thin chipboard - like cereal box chipboard, not the actual HEAVY chipboard. Since the Sizzlits are not designed to cut anything but card stock and designer paper. HTH!
