Pellet Die Set with TiCN Coating for making 25 mm (~1 inch) pellets from powders.
Free fast shipping across USA and Canada
Die Set includes: Die sleeve, plunger rod, 2 x spacers, release ring and base plate.
This die set is made from the same hardened tool steel (Rockwell hardness >C60) as our other sets however it is coated with a thin layer of ultrahard TiCN (Rockwell hardness >C80). This coating provides additional protection when working with very hard materials such a Al2O3, prolonging lifetime of the set. It also has the added benefit of reducing friction on the die walls and improving corrosion resistance when working with materials which might attached the steel. 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.
Use this set if you are routinely using hard materials or those which might damage steel surface. If you would like us to make you a coated die set in another size - please contact us.
