Premium Stainless Steel Tumbling Media Pins – Made in Germany

Polish with precision using our 0.047” diameter x 0.255” length stainless steel tumbling media pins, engineered for maximum performance in rotary and magnetic tumblers. Manufactured from high-grade 302/304 stainless steel, these pins are rust-resistant, non-magnetic, and extremely durable—designed to last for thousands of cycles without breaking down.

Perfect for:

  • Wet tumbling brass cartridges

  • Polishing steel, aluminum, titanium, and other metals

  • Reaching small crevices and flash holes without jamming

 

✅ Key Features:

  • 0.047” (1.19mm) Diameter – passes easily through all primer flash holes

  • 0.255” (6.47mm) Length – avoids side-by-side sticking

  • German-made 302/304 stainless steel – corrosion resistant & precision cut

  • Reusable and ideal for reloading and jewelry applications

  • Compatible with rotary tumblers and magnetic tumblers

 

🔧 How to Use (Best Practices):

  1. Fill your tumbler with pins and brass, leaving space for proper tumbling.

  2. Add clean, hot water (cold works, but hot improves cleaning speed).

  3. Use ½ tablespoon of dish soap (like Dawn) per 1 lb of brass.

  4. Tumble for 30–120 minutes, checking every 15 minutes initially.

  5. Optional: Add dishwasher detergent powder (with citric acid) for extra shine.

  6. Rinse and separate brass immediately after the cycle to prevent residue sticking.

For best drying results, towel off the brass, then air dry on trays for several days.

Whether you’re reloading spent casings or polishing small metal parts, this media delivers consistent, high-luster results every time.
