Built on a high-strength open-web nylon construction, this disc maintains stiffness under pressure and resists tearing or fraying when working edges and irregular surfaces. Aluminum oxide mineral provides sharp, consistent cutting action that produces a uniform scratch pattern across ferrous and non-ferrous metals. The 4-inch diameter disc mounts via a 1\/2-inch arbor hole and is sold individually. It is used by metalworkers, fabricators, and finishing technicians who need reliable, repeatable surface prep results.\u003c\/p\u003e\u003cp\u003eThis disc is suited to bench grinder, angle grinder, or right-angle tool applications where controlled light material removal is required. It performs well on cleaning scale, oxidation, and light contaminants from metal surfaces and is appropriate for both shop and field finishing work. The open-web structure limits debris loading, extending disc life in continuous-use production environments. It is part of the Standard Abrasives Buff and Blend HS product line, which is available in Coarse, Medium, and Very Fine grades to match varying surface finish requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh-strength non-woven nylon construction resists tearing, fraying, and folding under high pressure\u003c\/li\u003e\n\u003cli\u003eAluminum oxide mineral delivers sharp cutting action and a consistent, smear-free scratch pattern\u003c\/li\u003e\n\u003cli\u003eOpen-web design is load resistant, reducing debris buildup and extending service life\u003c\/li\u003e\n\u003cli\u003ePerforms light deburring and final finishing on ferrous and non-ferrous metals without gouging the substrate\u003c\/li\u003e\n\u003cli\u003eAvailable in three grades: Coarse, Medium, and Very Fine for varying degrees of aggressiveness\u003c\/li\u003e\n\u003cli\u003eCenter arbor hole design accommodates standard 1\/2-inch arbor mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard bench grinders, angle grinders, and right-angle finishing tools equipped with a 1\/2-inch arbor.
