The ceramic abrasive grain delivers consistent cut rate and durability through demanding grinding and finishing cycles. Rated at a maximum of 30,000 RPM, this disc brush handles high-speed rotary tools without loss of structural integrity. The Type R Quick-Change connector allows fast, tool-free mounting and removal on compatible mandrels, reducing changeover time in production and field applications. At 120 grit, it falls in the fine grade range, making it well suited for light material removal and refined surface prep work.\u003c\/p\u003e\n\u003cp\u003eThis disc brush is used in metalworking, fabrication, and maintenance applications where controlled surface finishing is required. Common tasks include weld blending, edge deburring, and light rust or scale removal on steel and similar alloys. The straight disc configuration and 1-inch outside diameter make it practical for tight-radius work and confined areas that larger abrasive tools cannot access. Machinists, fabricators, and maintenance technicians working in both shop and field settings regularly use this style of brush with die grinders and other high-speed rotary tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-inch outside diameter for work in confined or tight-radius areas\u003c\/li\u003e\n  \u003cli\u003e120 grit ceramic abrasive for fine-grade surface finishing and light material removal\u003c\/li\u003e\n  \u003cli\u003eType R Quick-Change connector for fast, tool-free mandrel mounting\u003c\/li\u003e\n  \u003cli\u003e30,000 RPM maximum speed rating suitable for high-speed die grinders\u003c\/li\u003e\n  \u003cli\u003eWhite ceramic abrasive grain construction for consistent cut performance\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch trim length provides controlled brush contact and deflection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Type R Quick-Change mandrels on high-speed die grinders and rotary tools capable of accepting 1-inch disc brushes at up to 30,000 RPM.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist, fabricator, or maintenance technician using a compatible Type R Quick-Change mandrel.
