That makes centerless grinding a relatively simple process that's ideal for finishing the outside diameter of small cylindrical metal parts requiring a tight tolerance. Centerless grinding is virtually continuous because, compared with grinding between centers, the loading time is small. So, long lengths can be ground continuously.

Considering the type of work you do will define the grit you need. Depending on your style, you will need an 80 or 180 grit wheel. For a consumer who enjoys reshaping tools, then 80-grit is the ideal standard. This level will also help you craft tools if you get more advanced. The 180 grit is best for people who do not perform that much grinding.
