Rated for a 4-inch diameter with a 1-inch arbor, this disc uses micron-graded diamond mineral secured by a metal bond for aggressive, consistent stock removal. The semi-flexible backing conforms to contours and edges, making it well-suited for finishing curved or irregular surfaces in stone, glass, ceramic, carbide, and composite materials. It mounts via a quick-release attachment system and is intended for use by fabricators, tool-and-die technicians, and composites finishers working with precision abrasive equipment.\u003c\/p\u003e\u003cp\u003eThis disc is designed for applications involving hard-to-grind materials such as stone, glass, ceramics, carbides, and composites in both production and job-shop environments. The open dot mineral pattern allows swarf and grinding debris to escape freely, reducing loading and extending usable disc life. It is appropriate for contour grinding, edge work, and surface finishing tasks where maintaining scratch consistency and cut rate across the full disc life is critical to part quality.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicron-graded diamond mineral delivers aggressive cut and consistent scratch pattern on hard materials\u003c\/li\u003e\n\u003cli\u003eOpen dot pattern allows swarf and debris to escape, reducing disc loading\u003c\/li\u003e\n\u003cli\u003eMetal bond anchors diamond securely for extended abrasive life\u003c\/li\u003e\n\u003cli\u003eSemi-flexible backing conforms to edges, contours, and curved surfaces\u003c\/li\u003e\n\u003cli\u003eQuick-release attachment system for fast disc changes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard production disc for 4-inch random orbital and disc grinders equipped with a 1-inch arbor and compatible quick-release backing systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and disc changes should be performed by a qualified fabricator or abrasive equipment operator with the grinder fully powered down and unplugged. Verify the grinder spindle speed rating meets or exceeds the disc maximum operating speed before mounting. Inspect the backing pad and disc face for damage before each use.
