Use it when
The fit is obvious.

- · Choose discs when you care about cleaner scratch patterns and faster progression through multiple grits.
Skip it when
The job asks for something else.
- · Skip discs when the work is mostly edges, profiles, or tiny repairs that are easier to control by hand.
- · Skip discs when you do not own the matching sander and do not want to buy into a machine workflow.
- · Skip it if you are solving a very different stage of the sanding sequence than this product was picked for.
- · Skip it if you already know you want the premium option and do not want a compromise purchase.
