4 mm Pellet Press Die Set

Pellet Die set for making 4 mm (~0.16 inch) pellets from powders. At such small diameters, you need such a small force (around 100 lb!) for very high stresses on the powder. We do not suggest using with a hydraulic press which does not have an accurate read out for low forces. Do not use this die with a big, heavy press - you can easily exceed the yield stress of the steel. You can even push down hard with your hand or tap it with a mallet to create sufficient force for compaction.
