3M 7010326840 Roloc Disc Pad Tr 4 Inches 5/8-11 Internal

Product Description

The 3M 7010326840 is a medium-grade rubber backup pad engineered to support Roloc TR 4-inch diameter abrasive discs during grinding, blending, and finishing operations. The pad features a 5/8-11 internal thread mount, allowing direct attachment to any power tool with a 5/8-11 external threaded shaft. Its medium rubber durometer provides consistent disc support across the working face, helping abrasive discs maintain surface contact during use. Weighing 0.31 pounds, the pad is compact and well-suited for handheld angle grinders and straight die grinders used in fabrication, bodywork, and maintenance applications.

This backup pad is intended for use with 3M Roloc TR 4-inch abrasive discs and fits sanders or grinders with shaft lengths of 5/8 inches or shorter. It is commonly used in metal fabrication shops, automotive body repair, and general industrial maintenance where quick disc changes and repeatable surface preparation are required. The Roloc TR system allows tool-free disc swaps, reducing downtime between abrasive changes during production or field service work.
