Raytech Microbrite Porcelain Media, 3mm

Get a high-polish finish without the harsh marks—Raytech Microbrite porcelain ball media is engineered to deliver a smooth, distortion-free result on delicate surfaces. Its 3mm round shape ensures a single contact point per bead, reducing friction while still achieving an effective polish, even in hard-to-reach areas. Perfect for fine jewelry components, wire forms, and other precision work, this media is especially suited for light deburring, burnishing, and edge smoothing on soft metals and delicate parts.

Made in the USA and designed for compatibility with all major vibratory and magnetic tumblers, this media works best with a quality burnishing compound. For optimal results, pair it with 2mm or 4mm media for more dynamic tumbling action.
