Measuring 7 inches in diameter with a 5\/8 inches-11 threaded hub, this disc mounts directly to large angle grinders used in fabrication, welding, and heavy grinding applications. The 80 grit zirconia abrasive delivers a balance of cut rate and surface finish, making it well suited for weld blending, edge grinding, and stock removal on steel and stainless steel. The Type 29 conical profile increases abrasive contact area on flat workpieces, improving both efficiency and disc longevity. Each disc weighs 0.81 pounds. Sold individually.\u003c\/p\u003e\u003cp\u003eThis disc is used in metal fabrication shops, structural steel work, pipe welding, and general industrial grinding. The 7-inch diameter and 5\/8 inches-11 arbor size match standard large-body angle grinders common in professional trade environments. Typical users include ironworkers, welders, pipefitters, and maintenance mechanics who require consistent material removal on ferrous and non-ferrous metals. The 80 grit rating positions this disc for medium-to-aggressive work where surface prep or weld cleanup is the primary task.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 29 conical profile increases surface contact for efficient flat grinding and blending\u003c\/li\u003e\n\u003cli\u003eZirconia abrasive grain provides high cut rate with extended disc life on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003e80 grit for medium-to-aggressive stock removal and weld blending\u003c\/li\u003e\n\u003cli\u003e7-inch diameter with 5\/8 inches-11 threaded hub fits standard large angle grinders\u003c\/li\u003e\n\u003cli\u003eWeighs 0.81 pounds per disc for balanced performance on high-RPM tools\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use abrasive for large angle grinders accepting a 7-inch disc with a 5\/8 inches-11 threaded arbor.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and disc changes should be performed by a qualified operator following ANSI B7.1 and tool manufacturer guidelines.
