Free fast shipping across USA and Canada
Pellet Die Set includes: Die sleeve, plunger rod, 2 x spacers, release ring and base plate.
This set can be used for making 10x10 mm square briquettes.
Whilst dies steels are chosen for tolerating high stresses and pellet dies are heat treated fro superior properties, you can easily exceed even these high yield strengths with a hydraulic press with a few pumps of the handle.
Die made of hardened tool steel (Rockwell hardness >C60) for long lasting trouble free performance. Sleeve is polished to high tolerances to allow the hardened tool steel plunger to slide through perfectly. Plunger and spacers are made from high yield strength steel, machined and polished to high tolerance for the perfect fit. Interior surfaces ground to mirror-like finish.
