Product Description
This 1kg pack of stainless steel ball shot media is designed for burnishing, polishing, and brightening jewellery in rotary tumblers. Manufactured from durable 304-grade stainless steel, the round ball-shaped media provides smooth, even surface contact, helping produce a bright, polished finish on sterling silver, gold, copper, brass, and other suitable jewellery metals.
Unlike mixed-shape tumbling media, this set contains round balls only, measuring 3Β mm in diameter. The spherical shape provides consistent contact across accessible metal surfaces, making it particularly useful for burnishing rings, pendants, earrings, bangles, and other jewellery components where a smooth, uniform finish is desired.
When used with water and a suitable tumbling soap, such as Tumblex Gleam (Roll Gleam), the stainless steel balls repeatedly contact and burnish the metal surface, helping improve shine and smooth minor surface irregularities. The round shape also reduces the risk of pointed media becoming lodged in small openings or delicate jewellery details.

-
Add Water: Add clean water according to the tumbler manufacturer's recommended operating level.
-
Add Tumbling Soap: Use a suitable burnishing compound such as Tumblex Gleam (Roll Gleam) to help clean and lubricate the media.

Ball Shot vs Mixed-Shape Shot
Ball-shaped shot is ideal for general burnishing and producing a smooth, even finish across accessible metal surfaces. Its rounded profile provides consistent contact without the pointed ends found on some other tumbling media.
Mixed-shape shot combines balls, pins, and other profiles to reach grooves, recesses, and detailed areas that round balls may not contact effectively. For jewellery with intricate details or difficult-to-reach surfaces, mixed-shape media may provide more comprehensive coverage.
Important Information
Stainless steel ball shot is a burnishing media, not an abrasive cutting media. It works by repeatedly contacting and compressing the metal surface to improve shine and smooth minor surface irregularities. It will not remove deep scratches, heavy casting marks, or significant surface defects. Jewellery should be appropriately prepared before tumbling for the best results.
Some delicate chains, hollow components, soft gemstones, and intricate settings may be unsuitable for steel shot tumbling. Always check that the jewellery is suitable for mechanical burnishing before use.
Although 304 stainless steel offers good corrosion resistance, the media should still be cleaned and dried after use. Avoid leaving the balls sitting in contaminated water or unsuitable cleaning solutions for extended periods.
This 1kg pack of stainless steel ball shot provides a durable, reusable burnishing solution for jewellers seeking smooth, bright, and consistent finishing results in rotary tumblers.
