• Mounted Rubber Points — A rubber-bonded point already fixed on its own shank.
• Ceramic & Porcelain Polishers — Polishes the ceramic itself, in place of a glaze layer.
• Polishing Discs — The finer steps of the same series.

Sequence: a review describes polishing in three stages, coarse finishing, intermediate polishing and final polishing. Coarse tools shape the work and remove excess material; medium ones smooth out the grooves and scratches the coarse ones leave.

Surface: 0.2 micrometres of roughness is considered the threshold for a clinically acceptable restoration.

Speed: OSHA's abrasive-wheel rule has the spindle speed checked against the maximum operating speed marked on the wheel.

Reuse: the CDC states that burs, polishing points and rag wheels used on contaminated appliances or prostheses should be heat-sterilised, disinfected between patients, or discarded.
