About grinding wheels
A grinding wheel is made of abrasive particles held together by a bond and grinds with its rim. OSHA groups abrasive wheels by bond: organic, such as resin, rubber or shellac, and inorganic, such as clay, glass or porcelain.
OSHA defines a grinding wheel as abrasive particles held together by a bond and used for grinding on its rim. OSHA defines an abrasive belt as a power-driven, flexible, coated band used for grinding, polishing or buffing.
How the types on this shelf differ
- Grinding Wheels — The coarse step: it shapes the work and removes excess material.
- Flexible Silicone Polishers — The abrasive is embedded in a flexible silicone body.
- Polishing Wheels — A wheel for the smoothing steps that follow grinding.
- Buffing Wheels — Carries the polishing agent to the work.
- Abrasive Discs — Grinds and smooths with its face.
- Mounted Rubber Points — A rubber-bonded point already fixed on its own shank.
- Polishing Discs — The finer steps of the same series.
- Separating & Cut-Off Discs — A thin wheel for cutting, where an abrasive disc works on its side.
- Mounted Stones — A rigid bonded abrasive, for grinding and shaping.
- Ceramic & Porcelain Polishers — Polishes the ceramic itself, in place of a glaze layer.
Heatless wheels are also filed here; no source on our allowed list describes them, so this guide does not.
What to look at when choosing
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.
Dust: the CDC names grinding and polishing castings and porcelain among the laboratory steps that put dust in the air.
