Product Description

The 3M 7010326831 is a disc pad hub designed for use with abrasive face plate systems on angle grinders and right-angle tools. It features a 5/8-11 internal threaded metal insert that accepts standard grinder spindles, providing a secure mechanical connection between the tool and the face plate. The hub measures 2.5 inches in diameter and is packaged loose without paperboard inserts, reducing material waste on the job site. Licensed tradespeople working with surface preparation, weld blending, or stock removal applications will find this hub compatible with a range of face plate configurations.

This disc pad hub is suited for metalworking, fabrication, and general surface conditioning applications in both shop and field environments. It is compatible with 4.5-inch and 9-inch face plates, making it adaptable across common angle grinder setups. The 5/8-11 internal thread is the industry-standard spindle thread found on most 4.5-inch and larger right-angle grinders, so integration into existing tool inventories is straightforward.
