Frankford Arsenal 2 lb Stainless Steel Tumbling Media Pins
The Frankford Arsenal pins are designed for ease of use and reliable performance in brass cleaning workflows. These pins are magnetic for convenient handling, helping prevent rust and loss during tumbling. With a compact 1mm by 7mm profile, they provide thorough interior cleaning without aggressive abrasion. This batch is ideal for replenishing existing media or handling smaller tumbler batches.
2.5 lb Stainless Steel Tumbling Media Pins for Tumbler
These 0.039-inch diameter pins offer a robust solution for brass cleaning and deburring. The magnetic construction supports easy handling, and the 0.255-inch length provides substantial contact with interior surfaces. Compatible with Frankford Arsenal tumblers and other rotary systems, this media is designed to withstand corrosive cleaning solutions while maintaining shape integrity over multiple uses.
2.5 lb Stainless Steel Tumbling Media Pins
GANGOU’s 2.5-pound pins combine rust resistance with reliable performance in heavy-duty cleaning cycles. The 0.039″ diameter and 0.255″ length deliver consistent agitation within brass cases, helping to remove residual powder residues and primer pockets. The magnetic design enhances loading efficiency, making it easier to manage media in and out of the tumbler.
BC Precision 1 LB 1/8″ Stainless Steel Tumbling Media Shot Jewelers Mix
The BC Precision mix offers four shapes—balls, diagonals, ballcones, and pins—to maximize contact variety and surface coverage. This 1/8″ size is versatile for finishing tasks across different brass calibers. Made from 304 stainless steel, the media resists rust and corrosion, providing durable performance in rotary tumblers and vibratory systems alike. Suitable for mixed-shape finishing workflows where surface texture uniformity matters.
BC Precision 2 LB 1/8″ Stainless Steel Tumbling Media Shot Jewelers Mix
This larger BC Precision batch increases total media surface area while maintaining a balanced mix of shapes. The 1/8″ size continues to suit delicate and precise finishing tasks across larger batches. As with the 1 lb version, all shapes are crafted from rust-resistant 304 stainless steel for long-lasting use in challenging cleaning cycles.
1/8″ Stainless Steel Tumbling Media for Jewelers 2 LBS Mix Shapes
GANGOU’s 2-pound mix provides a balanced assortment of 1/8″ balls and balcones designed for jewelers’ finishing tasks. Rust and corrosion resistance ensure dependable performance in wet or dry tumbling environments. The combination of shapes helps achieve uniform polishing while maintaining control over the final surface texture of case interiors and exterior prep.
Buying Guide: Key Purchase Considerations
- Media type and shape: Pins deliver rapid interior cleaning, while mixed shapes (balls, diagonals, ballcones, pins) provide broader surface coverage for diverse finishes. Choose based on the desired surface texture and batch size.
- Size and density: Smaller 1/8″ media offers finer finishing and detail work, while 0.039″ pins are optimized for aggressive cleaning in tighter interiors. Match size to your tumbler capacity and brass calibers.
- Material quality: Opt for 304 stainless steel to resist rust and corrosion. This improves life span and reduces the risk of introducing contaminants into brass.
- Magnetic handling: Magnetic media simplifies loading and unloading, lowers the chance of losing media, and helps maintain a clean workflow in busy reloading setups.
- Compatibility: Confirm tumbler compatibility with your equipment, including Frankford Arsenal models or other rotary tumblers. Media may vary in performance depending on machine speed and load.
- Batch size and maintenance: Larger batches require more media and more frequent sorting to remove fines. Periodic rotation and inspection help maintain uniform cleaning results.
- Finish goals: For primer-pocket cleaning and internal case body polishing, pins often excel. For overall surface finishing and uniform texture, mixed-shape media can be advantageous.
Across these options, the common advantages are rust resistance, stable performance under frequent use, and a range of shapes to tackle different cleaning challenges. The selections favor steel media that maintains integrity under wet and harsh chemical conditions, which is essential for steel-based tumbling in brass finishing workflows.
