These roller pressure dies work with all of our dies, and also are machined down for use with our mandrel attachment. These are only needed for sizes 1.75 and larger and combo dies. The smaller sizes work great with our standard roller pressure dies.
If you are mandrel bending on a 6.0 CLR, you need 2 roller pressure dies. Only one of them needs to be this machined down type. It is okay if you have both in this type as well
