Pellet Die set for making 50 mm (~2 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.
50 mm (~2 inch) pellet die sets are commonly used for pellet preparation for XRF which require larger surface area compared to other techniques and for thin film research for making sputtering targets and pulsed laser deposition targets. These wider diameter dies can take large loads through them - 60 tons which is beyond the limit of most lab presses. You do not need to get to such high forces though for great pellets.
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 | 121,000 lb (60 ton, 540 kN) |
| Typical force for quality pellets | 15250-45500 lb (7.5-23 ton, 70-210 kN) |
| Die sleeve inner diameter | 50 mm (1.97 inch) |
| Die sleeve height | 50 mm (1.97 inch) |
| Die sleeve outer diameter | 70 mm (2.76 mm) |
| Assembled height with spacers (w/o powder)* | 104 mm (4.09 inch) |
| Assembled height no spacers (w/o powder)* | 84 mm (3.31 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.

**Pending on the material you are pressing with and the method of loading the die set.
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.
