Pellet Die set for making 3 mm (~1/8 inch) pellets from powders.
With your die set order we’ll include:
- Die sleeve
- Plunger rod
- 2 x spacers
- Base plate
- Aluminium release ring with cutout for viewing pellet during release
Shipping: Free fast shipping across USA and Canada
Material: hardened tool steel (Rockwell hardness >C60) polished to a high tolerance fit.
This is the smallest die we stock. 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.
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.

| Yield Strength Hardened Steel | 80,000 psi (550 MPa) |
| Recommended max loading @ 50 % | 40,000 psi (275 MPa) |
| Recommended max force | 440 lb (0.2 ton, 1.9 kN) |
| Typical force for quality pellets | 55-164 lb (0.03-0.08 ton) |
| Die sleeve inner diameter | 3 mm (0.118 inch) |
| Die sleeve height | 40 mm (1.57 inch) |
| Die sleeve outer diameter | 45 mm (1.77 inch) |
| Assembled height with spacers (w/o powder)* | 92 mm (3.66 inch) |
| Assembled height no spacers (w/o powder)* | 80 mm (3.14 inch) |
*If making thicker pellets, the die set can operate just the same without spacers.
Safety:
- Always wear googles and safety protection equipment
- Clean well after use to prevent rusting.
- Do not apply pressure beyond shown on table.

D2 Tool Steel. For most pellets this material will be perfect for the job. Hardened D2 tool steel (Rockwell hardness >C60) for long lasting trouble free performance. The sleeve is polished to high tolerance to allow hardened tool steel plunger to slide through perfectly. Plungers and spacers are made from high yield strength steel, machined and polished to high tolerance for the perfect fit. Interior surfaces are ground to mirror-like finish. Release ring is made of aluminum.
Stainless steel. For a die set with great corrosion resistance and with for those heating for heating their dies up to max 250°C (482°F), this is a great choice. Stainless steel is a more expensive starting material and is slower to machine which leads than a slightly higher costs than our regular die sets. Our stainless die sets are heat treated for high hardness (~58) and have extremely high strength (160, 000 psi).

Recommended max force = Is the maximum force you can put the die set under. This includes a 50% safety margin which is industry standard.
Typical force for quality pellets = This is the range we recommend using that will get you a great pellet and is much less than the recommended max force.
