Built with 3M Precision Shaped Grain, the disc delivers higher cut rates and a cooler grinding temperature compared to conventional fibre discs. A grinding aid is integrated into the bond system to further reduce heat buildup, making this disc well suited for heat-sensitive alloys. The stiff fibre backing and strong resin bond resist tearing during aggressive grinding passes. At 36 grit and a rated speed of 20000 RPM, it handles weld removal, beveling, blending, and edge chamfering in demanding fabrication and finishing environments.\u003c\/p\u003e\n\u003cp\u003eThis disc is sized at 3 inches in diameter and uses the Roloc quick-change attachment system, allowing tool-free disc changes on compatible right-angle grinders and disc grinders. It is primarily used on stainless steel and high nickel alloys in industrial fabrication, maintenance, and metalworking applications. Common tasks include weld grinding, surface blending, and finish refinement where heat control and cut consistency are critical. The disc is sold individually and is suited for professional metalworking and fabrication trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3M Precision Shaped Grain delivers higher cut rates and cooler operation than conventional fibre discs\u003c\/li\u003e\n  \u003cli\u003eIntegrated grinding aid minimizes heat buildup, protecting heat-sensitive alloys such as stainless steel and high nickel alloys\u003c\/li\u003e\n  \u003cli\u003eStiff fibre backing and strong resin bond resist tearing in heavy-duty grinding applications\u003c\/li\u003e\n  \u003cli\u003eRoloc attachment provides secure, tool-free disc changes\u003c\/li\u003e\n  \u003cli\u003e36 grit coated abrasive suited for weld removal, beveling, blending, and edge chamfering\u003c\/li\u003e\n  \u003cli\u003eRated to 20000 RPM for use with standard right-angle disc grinders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Roloc-compatible right-angle grinders and disc grinders that accept 3-inch quick-change fibre discs.
