Part of the Merit Surface Prep series, it uses aluminum oxide abrasive grain with a polyester and nylon web backing. The disc carries a Fine grade rating and is rated to 30000 RPM, making it suited for high-speed rotary tools. Clean Bond resin technology keeps the work surface smear-free, while the high-loft nylon fiber construction supports extended service life across repeated passes.\u003c\/p\u003e\n\u003cp\u003eThis disc fits TR (Type III) quick-change systems with a Type R attaching button and mounts on die grinders, inline grinders, straight grinders, and handheld disc sanders. It is intended for use on 300 and 400 series stainless steel, hard and soft carbon steels, tool steels, super alloys, titanium, and fiberglass and composites. The Fine grade makes it appropriate for light to moderate material removal and surface conditioning tasks in fabrication, maintenance, and repair applications across industrial and trade settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive grain delivers consistent cut rate on ferrous and non-ferrous substrates\u003c\/li\u003e\n  \u003cli\u003eHigh-loft polyester and nylon web backing extends disc life under repeated use\u003c\/li\u003e\n  \u003cli\u003eClean Bond resin technology minimizes smearing and loading on finished surfaces\u003c\/li\u003e\n  \u003cli\u003eTR (Type III) quick-change interface with Type R attaching system for fast swaps\u003c\/li\u003e\n  \u003cli\u003e30000 RPM maximum speed rating suits standard die grinder and inline grinder operation\u003c\/li\u003e\n  \u003cli\u003eFine grade targets surface conditioning, blending, and light stock removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for TR (Type III) quick-change Type R attaching systems.
