The Vacalon Abrasive Dressing Stone dresses, trues and cleans abrasive rotary instruments such as stones and wheels. It takes off surface glazing, embedded debris and uneven wear so the tool cuts the way it did when new.
What it is used for
- Dressing and reshaping abrasive stones and wheels
- Removing material buildup and glazing
- Correcting uneven wear
- Use it whenever a tool cuts more slowly, loads up or wears unevenly – regular dressing extends tool life

About mounted stones
A lab mounted stone is a bonded abrasive, abrasive particles held together by a bond, fixed on its own shank for grinding and shaping. 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.
- Rotary Points — Lab points and silicone, rubber and polyurethane polishers.
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.
