Built on a non-woven construction with aluminum oxide abrasive at a medium grade (density 6), this disc mounts quickly to any Roloc TR-compatible right-angle die grinder or finishing tool. At 2 inches in diameter and rated to 22,100 RPM, it handles tight access areas and contoured surfaces where larger discs cannot reach. It is well suited for deburring, weld blending, and light stock removal in fabrication and HVAC sheet metal work.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in light industrial, fabrication shop, and field service environments where fast disc changes and consistent surface finish matter. It is appropriate for use on mild steel, stainless steel, aluminum, and similar metals. The 2-inch format fits compact Roloc TR tool heads, making it useful for detail work around fittings, flanges, and weld joints. HVAC technicians, pipefitters, and sheet metal workers commonly use this disc size for spot finishing and seam cleanup during installation or rework.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with medium grade for general-purpose surface conditioning and blending\u003c\/li\u003e\n  \u003cli\u003eNon-woven construction conforms to contoured and irregular surfaces without loading or glazing\u003c\/li\u003e\n  \u003cli\u003eRoloc TR quick-change attachment allows tool-free disc swaps on compatible right-angle grinders\u003c\/li\u003e\n  \u003cli\u003e2-inch diameter reaches tight spaces, corners, and detail areas inaccessible to larger discs\u003c\/li\u003e\n  \u003cli\u003e22,100 RPM maximum speed rating suits standard die grinder operating ranges\u003c\/li\u003e\n  \u003cli\u003eSeries XL-UR with density 6 for consistent cut rate and surface finish across applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Roloc TR-style quick-change tool holders on right-angle die grinders and finishing tools that accept the TR locking hub interface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a trained technician or skilled trade worker using a Roloc TR-compatible die grinder. Inspect the disc for damage before mounting and confirm the tool spindle speed does not exceed the 22,100 RPM disc rating.
