ADD8018120 Straight Disc Brush 120 Grit","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\n\u003cp\u003eThe BRUSH RESEARCH MFG. ADD8018120 is a 3-inch straight disc brush designed for surface finishing, deburring, and edge blending across a wide range of materials. It uses a ceramic and silicon carbide abrasive filament at 120 grit, placing it in the medium grade range. Each round filament measures 0.022 inches in diameter, delivering consistent cut action without loading or glazing. The drive arbor connector attaches to standard rotary tools and angle grinders. With a maximum rated speed of 4,250 RPM and a trim length of 0.7087 inches, this brush maintains controlled contact across flat and contoured surfaces. Licensed trades and industrial maintenance technicians reach for this type of tool when mechanical abrasion must stay precise and repeatable.\u003c\/p\u003e\n\u003cp\u003eThis brush is suited for work on advanced composite materials, ceramics, composite materials, metal matrix, metallics, plastics, super alloys, and wood. It fits applications where conventional abrasive wheels risk surface damage or inconsistent stock removal. Typical use cases include weld prep, gasket surface cleanup, port work, and light deburring on machined components. The 0.63-inch shank diameter and 0.63-inch arbor hole with a 1\/4-20 arbor hole thread size make it compatible with common rotary tool arbors used in shop and field maintenance settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic and silicon carbide abrasive filaments for aggressive, consistent cut on hard materials\u003c\/li\u003e\n  \u003cli\u003e120 grit medium grade finish suitable for deburring and surface prep\u003c\/li\u003e\n  \u003cli\u003eRound filament shape at 0.022 inches diameter for uniform abrasive contact\u003c\/li\u003e\n  \u003cli\u003eDrive arbor connector with 1\/4-20 arbor hole thread for secure tool mounting\u003c\/li\u003e\n  \u003cli\u003eRated to 4,250 RPM for compatibility with standard rotary and angle grinder tools\u003c\/li\u003e\n  \u003cli\u003eWhite brush color allows visual wear monitoring during use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with rotary tools and angle grinders accepting a 0.63-inch shank diameter and a 1\/4-20 arbor hole thread.
