The disc measures 1 inch in diameter and uses 80 grit ceramic abrasive grain blended with aluminum oxide, molded directly into flexible bristles. Unlike wire brushes, the filled bristles maintain abrasive properties throughout the full service life of the disc. This tool is used by metal fabricators, HVAC technicians, pipe fitters, and other trade professionals working on metal surfaces that require consistent surface prep without aggressive material removal.\u003c\/p\u003e\n\u003cp\u003eThe 7100138172 is suited for both flat and contoured surfaces in residential and commercial applications. The flexible bristle construction allows the disc to conform to irregular geometries, producing consistent finishes on complex parts. It is well-suited for pre-weld prep, post-weld blending, paint and coating removal, and light deburring on metal pipe, fittings, sheet metal, and structural components. The Roloc attachment system allows quick disc changes when working through multi-step finishing processes, reducing downtime between grits or disc types.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e80 grit ceramic abrasive grain blended with aluminum oxide for consistent cut throughout disc life\u003c\/li\u003e\n  \u003cli\u003eFlexible molded bristles conform to contours and complex part geometry\u003c\/li\u003e\n  \u003cli\u003eBristle spacing optimized for coating removal and high-loading applications\u003c\/li\u003e\n  \u003cli\u003eRetains abrasive properties until end of disc life, unlike wire brushes that shed and dull\u003c\/li\u003e\n  \u003cli\u003eRoloc quick-change attachment system for fast disc swaps in multi-step finishing workflows\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Roloc-compatible right-angle grinders and die grinders that accept 1 inch quick-change disc mandrels.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and disc changes should be performed with the tool unplugged or air supply disconnected.
