How do MaxxMacro circle holders compare with older System 3R electrode holders for graphite machining?

A circular pallet can provide a practical mounting area for round or flat electrode blanks. The best choice depends on how the electrode fits on the pallet and how much support and machining access it needs.

For square blanks, a pocket holder can support the blank directly and may reduce the stock needed for attachment. Compare the complete fixture and electrode geometry when assessing material use; a particular saving cannot be assumed for every job.
