About mounted stones
A bonded abrasive is made of abrasive particles held together by an artificial or natural bond. OSHA's abrasive-wheel rule treats mounted wheels of 2 inches and under as a group of their own.
A mounted point or stone is an abrasive already fixed on its own shank; the FDA names the abrasive point among the abrasive devices of 21 CFR 872.6010, Class I. OSHA groups abrasive wheels by bond: organic, such as resin, rubber or shellac, and inorganic, such as clay, glass or porcelain.
How the types on this shelf differ
- Mounted Stones — A rigid bonded abrasive, for grinding and shaping.
- Mounted Rubber Points — A rubber-bonded point already fixed on its own shank.
- Flexible Silicone Polishers — The abrasive is embedded in a flexible silicone body.
- Polishing Wheels — A wheel for the smoothing steps that follow grinding.
- Grinding Wheels — The coarse step: it shapes the work and removes excess material.
- Ceramic & Porcelain Polishers — Polishes the ceramic itself, in place of a glaze layer.
What to look at when choosing
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.
Size: ISO 2157 sets the nominal diameters of the working part of burs, laboratory burs, grinding instruments, diamond instruments and mandrels, and how they are designated.
Shank: the part that fits into the handpiece. ISO 1797 sets shank dimensions and material properties.
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.
