The disc uses vortex agglomerated aluminum oxide grain bonded to a high-loft nylon web backing with a proprietary Clean Bond resin system. The fine-grade abrasive delivers consistent cut and surface finish without aggressive stock removal. Rated to 15,000 RPM, it attaches via a Type R quick-change system, making tool-free disc swaps fast during production or repair work. It is installed by metalworkers, fabricators, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis disc suits die grinder and handheld disc sander applications in industrial, fabrication, and maintenance environments. It is well suited to work on 300 and 400 series stainless steel, brass, bronze, cast iron, copper, ductile iron, gray iron, hard and soft carbon steels, super alloys, titanium, tool steels, and fiberglass and composite materials. Typical use cases include weld blending, light deburring, surface prep before coating, and finishing passes on soft metals where surface integrity matters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVortex agglomerated aluminum oxide grain for consistent cut rate and extended disc life\u003c\/li\u003e\n  \u003cli\u003eHigh-loft nylon web backing conforms to irregular and contoured surfaces\u003c\/li\u003e\n  \u003cli\u003eProprietary Clean Bond resin technology bonds abrasive grain to backing for durability under load\u003c\/li\u003e\n  \u003cli\u003eType R quick-change attachment system allows tool-free disc changes on compatible grinders and sanders\u003c\/li\u003e\n  \u003cli\u003e15,000 RPM maximum speed rating suits high-speed die grinder operation\u003c\/li\u003e\n  \u003cli\u003eFine grade suited for weld blending and finishing passes rather than aggressive material removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with die grinders and handheld disc sanders equipped with a Type R quick-change hub or mandrel.
