Diamond infused polishers for conventional ceramic materials.

Sigma Polishers provide the most efficient solution for contouring, smoothing and polishing all types of conventional ceramic materials. Infused with a high content of diamond grains, these polishers work quickly, and produce an ultra-smooth surface. Technicians are able to achieve an ultra-high luster without the use of pastes or compounds.

Each of our Sigma Polishers distinct grades has specific uses:

  • Coarse Grit (Blue) – quickly shape, contour and adjust contacts.
  • Medium Grit (Red) – smooths the surface and prepares it for final glaze.

Together, technicians can efficiently complete all types of ceramic tasks.
