You’ve heard of tumbling media for finishing jewelry; you’ve probably even used it. But there are many kinds, and each one has characteristics that make it better suited for one type of project, finish, or tumbler.
Stainless steel pins leave a semi-bright finish in a short amount of time, perfect for use right after casting. Use stainless steel pins with a magnetic tumbler, along with Stuller finishing soap.
This media can be used on all metals to produce an excellent mirror finish. Use it in a vibratory or barrel tumbler.
These plastic, pyramid-shaped media have a medium-cut surface and produce a very fine cut surface conditioning. They’re best for soft metals, to leave a smooth finish with little shine. Use these in a vibratory or barrel tumbler.
Stainless steel shot is rust- and corrosion-resistant, requires no special storage, and is ideal for use in wet, flow-through systems. Used in a vibratory or barrel tumbler, this stainless-steel shot leaves pieces bright and clean, burnishing metals to a mirror finish.
Because of their shape, 2mm porcelain balls impart a single point of contact, leaving a very fine finish to almost any area it reaches. It’s very popular for delicate parts, fine-edge blanking, and precious metal burnishing. Use them in a vibratory or barrel tumbler to create a bright finish with less distortion.
These plastic, pyramid-shaped media have a medium-cut surface and produce very fine surface conditioning. These pyramids are best for soft metals, to leave a smooth finish with little shine. Use them in a vibratory or barrel tumbler.
Ceramic is the heaviest tumbling media and the fastest finisher. Its polyhedron shape is great for grinding and polishing hard metals. It’s also good for deburring machined, casted, and fabricated parts. Use it in a vibratory or barrel tumbler.
