Product Description

The NORTON 66260302135 is a grinding wheel backup plate designed to support abrasive grinding wheels during cutting and grinding operations. The plate measures 6 inches in outside diameter with an inside diameter of 1.25 inches, a bore hole size of 1.25 inches, and an overall thickness of 0.3125 inches. It provides a rigid backing surface that helps maintain wheel stability and reduces flex under load.

It is appropriate for metal fabrication shops, maintenance facilities, and industrial production environments where consistent wheel support is required.
