Built around 3M Precision Shaped Grain, the disc delivers faster cut rates and cooler grinding temperatures compared to conventional fiber discs. A grinding aid is integrated into the construction to further reduce heat buildup, making it well suited for heat-sensitive alloys. The disc runs at a maximum of 8600 RPM on a 7-inch diameter platform. Licensed trades and metal fabricators rely on this disc for weld removal, blending, and finish refinement where surface integrity matters.\u003c\/p\u003e\u003cp\u003eThis disc is intended for use on stainless steel and high nickel alloys in both shop and field fabrication environments. Typical applications include weld grinding, beveling, edge chamfering, and surface blending. The stiff fiber backing and strong resin bond resist tearing under heavy lateral load. The quick-change interface mates with compatible disc pad face plates and hubs, allowing fast swap-outs during continuous production work. It is sold individually and is appropriate for professional metalworking, maintenance, and repair operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3M Precision Shaped Grain delivers higher cut rates and cooler grinding than conventional abrasive minerals\u003c\/li\u003e\n\u003cli\u003eIntegrated grinding aid minimizes heat buildup on heat-sensitive alloys such as stainless steel and high nickel alloys\u003c\/li\u003e\n\u003cli\u003eQuick-change mounting for fast disc swaps with compatible 3M disc pad face plates and hubs (sold separately)\u003c\/li\u003e\n\u003cli\u003eStiff fiber backing and strong resin bond provide durability and tear-resistance under heavy use\u003c\/li\u003e\n\u003cli\u003e7-inch diameter, 80-grit coated construction suited for weld removal, beveling, and blending\u003c\/li\u003e\n\u003cli\u003eRated to 8600 RPM for use with standard right-angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with 3M disc pad face plates and hubs designed for quick-change fiber disc systems (sold separately).
