Measuring 3\/4 inches in diameter, this non-woven disc uses vortex agglomerated aluminum oxide grain bonded to a flexible, high-loft nylon web backing with proprietary Clean Bond resin technology. The coarse 80-grit construction cuts aggressively while the non-woven structure conforms to irregular surfaces. It is rated up to 40000 RPM and attaches via a Type R attaching system, compatible with handheld disc sanders. Licensed tradespeople and skilled fabricators are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for handheld disc sander applications in metal fabrication, welding shops, plumbing, and mechanical trades where surface prep and finishing are required. It performs across a broad range of materials including 300 and 400 series stainless steel, brass, bronze, cast iron, copper, ductile iron, fiberglass and composites, gray iron, hard and soft carbon steels, super alloys, titanium, and tool steels. The flexible nylon web backing allows the disc to follow contours on pipe, fittings, and fabricated assemblies, making it useful in both bench and field work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTR (Type III) quick-change mount with Type R attaching system for fast disc swaps on compatible handheld sanders\u003c\/li\u003e\n  \u003cli\u003eVortex agglomerated aluminum oxide grain delivers consistent, aggressive stock removal at coarse 80-grit\u003c\/li\u003e\n  \u003cli\u003eProprietary Clean Bond resin technology bonds grain to high-loft nylon web for durability and open structure\u003c\/li\u003e\n  \u003cli\u003eFlexible nylon web backing conforms to curved and irregular workpiece surfaces\u003c\/li\u003e\n  \u003cli\u003e40000 RPM maximum rating supports high-speed handheld tool use\u003c\/li\u003e\n  \u003cli\u003eCompatible with a broad material range including stainless, titanium, cast iron, copper, and fiberglass composites\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with handheld disc sanders equipped with a TR (Type III) or Type R quick-change interface.
