OVAL BALLS

Used for vibratory finishing and barrel tumbling operations when a scratch and dimple-free finish is required. This shape introduces an oscillating motion to the finishing mass and provides more surface-to-surface contact than balls.

DIAGONALS

Particularly suited to odd shapes where lodging might be a problem or for parts with hard to reach angles. Beveled edges of diagonally cut ends provide effective finishing action in corners. The cylindrical body offers wide area contact.
