It clips onto a hand pad or backup pad using standard clamps or clips, making it practical for hand-sanding applications where controlled material removal and surface refinement are required. Finishing technicians and surface prep professionals working in auto body, marine, and metal fabrication environments will find this disc a reliable choice for wet or dry finishing operations.

This disc is suited for finishing applications on a variety of substrates including paint, e-coat primer, gel coat, and metal. It is commonly used in auto body shops, marine refinishing, and general metal finishing where a consistent, fine finish at P500 grit is needed. The mesh cloth construction allows the disc to be run wet or dry, expanding its utility across different workflow preferences and surface conditions.
