Pellet Die Set 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.

25 mm (~1 inch) pellet die sets are some of the most common sizes found around the lab. The size of the pellet makes them easy to handle around the lab and typically contains a manageable 3-12 g of powder depending on the material density. 25 mm 1 inch is a common pellet die size for solid state synthesis (shake and bake) synthesis of materials and of preparation of pulsed laser deposition targets.

Standard material is 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.

Ultrahard TiCN material 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.
