Rulletti e dischetti refers to the broad family of small wheels and discs fitted to compressed-air turbines for operations on marble surfaces. Le voci del marmo emphasizes the variety of shapes, sizes, and compositions available.
Etymology
Italian: rulletti, “small rollers,” + dischetti, “small discs.”
Sculptor Notes
The attachment determines the cut. A small rotary tool is really a platform: abrasive, diamond, carbide, rubberized, or polishing heads each produce a different surface and should be selected according to access, required removal rate, and desired finish.
