Diamond Flywheels -Shank - 90°

This 90-degree diamond flywheel is a precision rotary tool used for creating brilliant, mirror-like "bright cuts" on jewelry surfaces.  For high-speed use in a micromotor, allowing the diamond-tipped edge to slice through metal and leave a reflective finish that requires no further polishing. The 90-degree angle is ideal for V-shaped decorative grooves and faceted patterns on wedding bands and bangles. It is a critical tool for the "bright-cutting" technique, providing a sparkle that rivals pavé-set stones.
