This "Long Shaft" Hub threads onto the shaft of your long shaft grinder, allowing the end of the shaft to protrude through, so you can spin on a retaining nut over a traditional grinding disc, or spin on a TN threaded grinding disc.
This hub cannot be used on short shaft grinders, as it uses all the thread length.
See Related Products, below, for a hub suitable for use on short shaft grinders.
Use this Hub, and an appropriate Backing/Face Plate, with any Grinding Disc - either 3M's TN Quick-Connect spin-on discs, or traditional discs with a 7/8" center hole.
• Can be used with all 4" - 9" of backing plates
• See Related Products, below, for Grinding Disc Pad Backing/Face Plates
• If using traditional 7/8" hole discs, see Related Products, below, for Grinding Disc Retainer Nuts
