Built with an extremely flexible backing and 100 percent cotton abrasive construction, this Type R disc conforms closely to workpiece surfaces for consistent, controlled stock removal. At 40 grit, it delivers a coarse cut suited to initial surface prep and heavy grinding passes. Weighing just 0.0176 pounds, the disc is lightweight and easy to handle during extended use. It is intended for professional fabricators and metalworkers who require reliable performance on demanding surface conditioning tasks.\u003c\/p\u003e\u003cp\u003eThis disc is engineered for edge grinding applications on cold rolled mild steel and stainless steel sheet. Its flexible construction allows it to follow contours and edges without gouging or undercutting the base material. Typical use cases include weld seam blending, surface preparation before coating, and deburring operations in fabrication shops and field service environments. The Type R mount style provides a secure attachment to compatible right-angle grinders and disc holders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExtremely flexible backing conforms to edges and contours for even material removal\u003c\/li\u003e\n\u003cli\u003e100 percent cotton abrasive construction for consistent cut and finish\u003c\/li\u003e\n\u003cli\u003e40 grit coarse cut suited to heavy surface prep and edge grinding\u003c\/li\u003e\n\u003cli\u003e3-inch diameter in a Type R mount configuration\u003c\/li\u003e\n\u003cli\u003eRated for use on cold rolled mild steel and stainless steel sheet\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Type R compatible right-angle grinders and disc holders rated for 3-inch surface conditioning discs.
