Stainless Steel Polishing Media
Pickup currently not available
The most common application of stainless steel barrel polishing media is for polishing metals such as brass. Unlike corn cob or walnut shell media, stainless steel media can thoroughly polish both the interior and exterior of metal parts, including internal threads, blind holes, undercuts, and fine details that vibratory media cannot reach.
Stainless steel polishing media do not remove material—they work by causing plastic deformation of microscopic surface irregularities, compressing these irregularities to create a smooth, lustrous surface.

Stainless Steel Tumbling Media for Burnishing & Polishing
Norden’s stainless steel polishing media are specifically designed for batch finishing processes, including the polishing, cleaning, light deburring, and surface smoothing of metal parts. Unlike abrasive media, which remove material through aggressive cutting, stainless steel media primarily function through controlled contact and polishing. By applying pressure to the workpiece surface, these polishing media help smooth out microscopic surface irregularities and produce a bright, uniform surface finish. We offer a wide variety of stainless steel shapes and sizes to meet the requirements of different part geometries, materials, and surface finishes.
Key advantages: Ideal for polishing and high-gloss finishing; long service life with low consumption; Suitable for brass, copper, aluminum, and steel parts; available in a variety of shapes and sizes; helps treat holes, grooves, and recessed areas; pins reach internal threads, blind holes, and intricate details—no surface is left unfinished; compatible with magnetic polishing machines;
Custom media blending solutions available; direct factory supply for industrial and wholesale customers.

What are the different shapes of Stainless Steel Polishing Media?
Shape Selection
Choose the media shape according to where the media needs to reach on your part.
| Workpiece Characteristics | Recommended Shape | Main Reasons |
|---|---|---|
| Flat surfaces, outer surfaces, regular-shaped parts | Stainless Steel Ball Media | Even contact; suitable for general-purpose bright finishing, polishing, and surface finishing |
| Requires a larger contact area and continuous rolling contact | Stainless Steel Disc-shaped Media | Suitable for parts with recessed corners |
| Small holes, deep holes, narrow grooves, threads, and recesses | Stainless Steel Pin Media | The slender structure allows access to narrow areas, Reaches deep into internal threads, blind holes, and intricate openwork areas |
| Corners, edges, recesses, and complex curved surfaces | Stainless Steel Oblique Cylinder Media | The beveled ends facilitate access to corners while maintaining a large contact area |
For parts with complex structures, you can combine different shapes of grinding media to improve overall surface coverage.
If the part includes:
Flat surfaces + holes + corners
Recommended for:
Ball+ pin-shaped
Or Recommended for:
Disc-shaped + Oblique Cylinder + pin-shaped
This allows different shapes to cover different areas.
Our recommendation:
Send us photos or drawings of your parts. We'll recommend the optimal shape and size, then provide samples for testing.

Can stainless steel polishing media be used to polish aluminum?
Yes. Stainless steel grinding media can be used for suitable aluminum components, especially for burnishing and surface brightening. Media size and process parameters should be selected according to the part geometry and surface requirements.
Can stainless steel media polish brass?
Yes. Brass is one of the common applications for stainless steel burnishing media.
What size stainless steel media should I choose?
The media size should be selected based on the part dimensions and the smallest openings or recessed features. Smaller media can access tighter areas, while larger media provide stronger contact force on open surfaces.
Can stainless steel media of different shapes be used together?
Yes. Using a combination of media of different shapes and sizes can improve coverage of complex parts. The appropriate combination should be selected based on the part’s geometry and surface finish objectives.
What machines are stainless steel polishing media suitable for?
They are suitable for vibratory polishing machines and magnetic polishing machines. Choosing the right machine depends on the parts you want to polish and the desired level of polish.
