It is suitable for use on long shaft grinders, where the end of the threaded shaft extends through this hub, allowing for a backing plate and then threading on a TN equipped grinding disc or a retaining nut for a traditional 7/8" hole grinding disc.
• Use to support larger backup/face plates when using larger grinding discs
• Can be used with any 3M TN or 7/8" hole grinding disc of an appropriate size
