About abrasive discs
An abrasive disc is a disc faced with abrasive and used on its side for grinding or polishing. The FDA names the abrasive disc, and the guard for it, among the abrasive devices of 21 CFR 872.6010.
The FDA groups abrasive discs, abrasive points, polishing strips and polishing wheels as abrasive devices, Class I (21 CFR 872.6010): they remove excess restorative material and smooth rough surfaces, on a shank held by a handpiece.
OSHA's general-industry rules define a disc wheel as a rotating disc faced with abrasive and used on its side.
How the types on this shelf differ
- Separating & Cut-Off Discs — A thin wheel for cutting, where an abrasive disc works on its side.
- Abrasive Discs — Grinds and smooths with its face.
- Polishing Discs — The finer steps of the same series.
- Buffing Wheels — Carries the polishing agent to the work.
- 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.
What to look at when choosing a disc
Mandrel and bore: ISO 13295 covers the mandrels that carry discs and polishers. ISO 10323 sets the bore diameters that make discs and mandrels interchangeable.
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.
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.
