Material: hardened tool steel (Rockwell hardness >C60) polished to a high tolerance fit.

15 mm die sets make pellets of a nice handleable size for a range of applications and analytical techniques so if you are making a thin bisque of material, a battery electrode or electrolyte to fit in a coin cell or running some annealing treatments experiments, the 15 mm pellet die set might be the one for you!

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 (see our videos). 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.
