Creative

Engine-Turned Metal Art Panels

Create mesmerizing swirl patterns (engine turning) on aluminum or stainless panels. The 3 in. firm QRC mandrel keeps discs flat for crisp, even rosettes, and the quick-change hub lets you switch grits and Scotch-Brite style discs fast. Finish with a clear coat for wall art, coasters, or desk plates.


Satin-Finished Jewelry & Charms

Produce consistent satin and brushed textures on copper, brass, or aluminum pendants and earrings. Use the firm mandrel with fine abrasive and surface conditioning discs to bevel edges, deburr, and apply directional grain patterns before patina and sealant.


Resin/Wood Coasters with Polished Edges

Flush and polish resin to wood on small coasters and plaques. Step through grit levels using quick-change discs, then switch to non-woven polishing discs for a glassy edge finish that highlights resin transparency and wood figure.


Sculpted Steel Rose Finishing

After cutting and forming petals, blend welds, soften edges, and add texture with surface conditioning discs. The 3 in. size excels at tight contours, giving each petal a hand-finished sheen before heat coloring and wax.
