Measuring 3\/4 inches in diameter, the disc uses aluminum oxide abrasive grain bonded to a flexible polyester backing with Clean Bond resin technology. It is rated at a maximum of 40,000 RPM and carries a Very Fine grade (150 grit), making it appropriate for light material removal, blending, and smear-free finishing work. This disc is installed by machinists, fabricators, welders, and metal finishing technicians who require consistent surface results on tight geometries.\u003c\/p\u003e\n\u003cp\u003eThis disc fits TR (Type III) and Type R quick-change attaching systems and is compatible with die grinders and handheld disc sanders. The 3\/4 inches diameter suits work in confined areas and on contoured surfaces where larger discs cannot reach. Approved material applications include 300 Series 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 blue disc color and black button are standard identifiers for this product line.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive grain coating for higher cut rate relative to standard non-woven discs\u003c\/li\u003e\n  \u003cli\u003eClean Bond resin technology produces smear-free finishes on sensitive alloys\u003c\/li\u003e\n  \u003cli\u003eHigh-loft nylon fiber construction extends disc service life under repeated use\u003c\/li\u003e\n  \u003cli\u003eFlexible polyester backing conforms to contoured and irregular surfaces\u003c\/li\u003e\n  \u003cli\u003eTR (Type III) and Type R quick-change compatibility for fast disc swaps without tools\u003c\/li\u003e\n  \u003cli\u003eMaximum rating of 40,000 RPM for use with standard die grinders and handheld disc sanders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for TR (Type III) and Type R quick-change attaching systems.
