Product Description
This 1kg pack of mixed stainless steel shot media is designed for burnishing, polishing, and brightening jewellery in rotary tumblers. Manufactured from durable 304-grade stainless steel, the mixed shapes provide excellent surface coverage, helping produce a smooth, bright finish on sterling silver, gold, copper, brass, and other suitable jewellery metals.
The assortment combines round balls, satellite-shaped shot, and diagonal pins to reach different areas of jewellery during tumbling. Round balls provide smooth, even burnishing across exposed surfaces, while satellite and diagonal shapes help reach grooves, recesses, and detailed areas that larger round shot may not contact effectively.
When used with water and a suitable tumbling soap, such as Tumblex Gleam (Roll Gleam), the stainless steel media repeatedly contacts and burnishes the metal surface, helping improve shine, reduce minor surface irregularities, and produce a more consistent finish. The mixed-shape combination makes it particularly useful for finishing jewellery castings, rings, pendants, chains, findings, and other small metal components.

Important Information
Stainless steel 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 sanded and 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, it should still be cleaned and dried after use. Avoid leaving the media sitting in contaminated water or unsuitable cleaning solutions for extended periods.
This 1kg mixed stainless steel shot set provides a versatile, reusable burnishing solution for jewellers who want bright, consistent results across a wide range of jewellery shapes and surface details.
