A contact wheel is primarily used for making radiuses in a peice of material or for hollow grinding. We use these Wheels in our own builds & besides them being imported wheels they are exceptional quiality & do a very good job. they offer a medium/firm rubber that has an acceptable concentricity & is soft enough for belt bump not to be an issue.  
 
Manchester grinders offer these wheels in the UK & fully support them when bought through us. we also offer a Shaft making service.
 
Belt grinder is not included in this sale. Listing is for a contact wheel. Grinder for demonstration.
