Steel and Stainless Steel Media
Richwood supplies steel and stainless steel media for burnishing and finishing. Shapes include T-pins, ovalballs, cones, double pointed pins, diagonals, ballcones, and balls.
Each shape is built to reach specific part geometries. Ovalballs add oscillating motion and surface contact. Cones reach angles and curved surfaces. Diagonals work corners. Ballcones combine ball and cone action in one shape.

How to choose
Shape use cases
- Ovalballs: oscillating motion and greater surface-to-surface contact than mass finishing balls.
- Cones: center flange and tapered crowns reach angles and curved surfaces; small sizes suit ornamental designs.
- Double pointed pins: 1/16" to 1/8" diameters in lengths up to 1/2".
- Diagonals: beveled diagonally-cut ends finish corners; cylindrical body gives wide area contacts.
- Ballcones: combine ball and cone action in one proportioned shape.
- Balls ECLIPSE: round with slight flats at the pole ends.
- Balls ABCO: round and free from flats.
