Carbon Steel Shot Media - Sphere 1/8" (3.18 mm)

These 3.18 mm (1/8 inch) carbon steel spheres provide a consistent and predictable burnishing action in rotary and vibratory tumblers. Their uniform size ensures that they reach into the larger recesses of a jewelry design while providing a smooth finish on the exterior. Like all carbon steel media, they require proper maintenance to remain rust-free, but they offer an exceptionally long service life if cared for correctly. They are an excellent choice for finishing heavy chains, charms, and solid cast components where a bright, durable, and work-hardened surface is the primary goal.
