Why arent most organisations not carrying out COSHH assessments on abrasive wheels and discs??? When the are dressed or ground they turn from a solid to dust and the operator breathes this dust in. Is this a common thread??

Adequate extraction and PPE should control the risk, task based risk assessment is the key here.

Until they carry out a COSHH assessment they wont be able to determine the controls.

Hi,
The controls required are indicated on each individual MSDS for the wheel chosen and you will see that most grinding wheels are classed as non-harmful and present minimal risk, other than inhaleable dust produced during their use, and therefore adequate dust extraction at source will negate the risk to the operative, as does the provision of eye protection (for eye injury) and any other identified PPE, similarly.
Most grinding wheels are made up of numerous man-made and naturally occuring minerals and are not classified under EH40 as hazardous generally (therefore arguably not requiring COSHH assessment), and because they are compound in nature it is impractical to monitor each component, other than in the form of dust, and therefore a common WEL or STEL needs to be applied re dust exposure and this is only applicable where individual exposure nears this level (grinding is usually a very short duration task on bench grinders), to clarify on my previous response.

The COSHH for the materials upon which the disc is being used would almost always carry more hazard (Iron, Steel, Stainless etc.), or generate/contribute higher concentrations of low/non hazard dust to the exposure than the gradual wearing of the disc.
So you would assess the task not the disc as Peter says above, also agree that the control measures to protect against the materials being worked on would be more than sufficient to protect against the disc.

What if they on a surface grinder or form grinder dressing the wheel dry???

As an engineer by profession, neither of which I would dress by hand - I would mount the dressing tool in either the vice or directly on the table and use feed to dress, and therefore adequate extraction / enclosure of the wheel would negate any risk
