Frankford Arsenal 2 lb Stainless Steel Tumbling Media Pins
Material and size: 2 pounds of 1 mm x 7 mm pins. Design focus: magnetic for convenient handling and rust prevention. Use: replace lost pins or tumble smaller batches of brass. Benefits: ideal for cleaning inside primer pockets and the case body, and suitable for rotary tumbling. Best for small batches where precision cleaning is required and magnetic handling is a plus.
Who it’s best for: reloaders and small-batch brass cleaners who need precise interior cleaning without larger media. Why selected: compact pins offer targeted cleaning inside cases, reducing manual scrubbing. Caution: magnetic pins can attract ferrous contaminants; ensure contamination-free loads before tumbling.
FULLBOW 2.5 lb Stainless Steel Tumbling Media Pins
Material and size: Magnetic stainless steel 304 pins, 0.039 inch diameter, 0.255 inch length. Compatibility: designed to work with Frankford Arsenal tumblers. Benefits: corrosion resistant and packable in a sturdy jar. Use: brass cleaning media that fits well in standard rotary tumblers. Best for: shooters and reloaders who want reliable, compatible media with easy storage. Caution: verify tumbler compatibility to ensure smooth operation with magnetic media.
AOSWTLIF 14oz 1/8″ Stainless Steel Tumbling Media Shot (3 Shapes)
Shapes included: Ballcone, Ball, and Pin. Benefit: 360° polishing coverage on complex surfaces, such as jewelry chains and intricate metal parts. Deburring and rust removal are faster with 304 stainless steel, with a noted time reduction compared to ceramic media. Durability: 100% 304 stainless steel, rust-proof and long-lasting. Best for: jewelry makers and metal fabricators needing thorough polishing on multi-faceted pieces. Limitation: three-shape mix may require more careful separation when loading to avoid over-polishing certain areas.
BC Precision 2 Lb 1/8″ Diagonal Stainless Steel Shot
Material and shape: 1/8 inch diagonal stainless steel media. Benefits: provides enhanced cleaning and polishing action due to diagonal geometry. Use: suitable for rotary and vibratory tumblers, delivering consistent contact on surfaces. Best for: general-purpose finishing with a focus on uniform edge refining. Caution: diagonal shapes may require longer tumbling times for very intricate parts to avoid over-polishing corners.
BC Precision 2 LB 4-Shape Mix (Balls, Diagonals, Ballscones, Pins)
Shapes included: Balls, Diagonals, Ballcones, and Pins. Benefits: comprehensive surface coverage for diverse parts, offering versatility for different finishing tasks. Size: 1/8 inch (about 3.2 mm) media. Material: 304 stainless steel for rust resistance and durability. Best for: users who want a single mix capable of handling multiple finishing patterns. Caution: mixing shapes in one tumbler can lead to uneven wear if not balanced properly; adjust loading accordingly.
Buying Guide
What should you consider when choosing tumbler media for stainless steel?
- Load size and batch type: Smaller pins are ideal for precise interior cleaning of brass cases, while larger mixed shapes work well for jewelry and hardware with complex geometries.
- Shape variety: A mix of shapes (balls, diagonals, ballcones, pins) provides broader surface coverage and faster deburring for multi-faceted parts.
- Material and corrosion resistance: Look for 304 stainless steel for durability and rust resistance, especially in wet finishing processes.
- Compatibility: Some media is designed to work with specific tumbler models; check the manufacturer’s recommendations before mixing brands.
- Maintenance: Magnetic pins simplify handling and reduce rust risk, but ensure proper cleaning between batches to avoid cross-contamination.
- Finish goals: For light deburring and polishing, smaller media with gentle action may suffice; for heavy rust removal, larger or more aggressive shapes can accelerate results.
FAQ
- What is the main advantage of magnetic stainless steel pins? They are easy to handle, reduce rust risk, and work well for cleaning small interior spaces like primer pockets.
- Can I mix different shapes in the same tumbler? Yes, a 4-shape or 3-shape mix offers broad coverage, but ensure proper loading to avoid uneven finishing.
- Which media is best for jewelry polishing? 3-in-1 shape mixes, especially those with ballcones and pins, provide multi-angle contact for complex surfaces.
- Is 304 stainless steel necessary for tumbler media? It is a common standard because it offers good rust resistance and durability for wet tumbling.
- How do I choose the right size for my parts? Larger shapes cover more surface area, while pins and small balls are better for tight spaces and detailed features.
- Should I worry about rust on media? Look for rust-resistant finishes like 304 stainless steel, and store media in a dry, clean environment.
