It combines the precision-shaped grain technology of Cubitron II abrasives with the Roloca quick-attach system, allowing fast disc changes without tools. The 3-inch diameter disc runs at up to 20000 RPM and cuts at a 40-grit level. A poly-cotton X-weight backing resists tearing and fraying, making it reliable for edge work where standard discs commonly break down. Metal fabricators, welders, and grinding professionals install this disc for deburring, blending, and edge finishing tasks.\u003c\/p\u003e\u003cp\u003eThis disc is suited for light to medium-duty edge grinding and surface conditioning in fabrication shops, manufacturing environments, and field metalwork. The 3-inch format fits compact right-angle grinders and die grinders equipped with Roloca-compatible backing plates. The 40-grit specification positions it for stock removal and weld seam blending where a moderate cut rate and surface finish are both required. It is sold per each unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePrecision-shaped grain delivers sharp, cool, and consistent cutting action across the disc face\u003c\/li\u003e\n\u003cli\u003eEvenly spaced grain layout creates gaps that allow debris to escape, reducing loading\u003c\/li\u003e\n\u003cli\u003ePoly-cotton X-weight backing provides high tensile strength and resists fraying at edges\u003c\/li\u003e\n\u003cli\u003eRoloca attachment system enables fast, secure disc-to-tool mounting without extra hardware\u003c\/li\u003e\n\u003cli\u003e3-inch diameter and 40-grit rating suit edge blending and weld removal on ferrous metals\u003c\/li\u003e\n\u003cli\u003eRated to 20000 RPM for use with high-speed compact grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with compact right-angle grinders and die grinders fitted with a Roloca-compatible backing pad.
