Measuring 2.75 inches in diameter with a 0.012-inch wire diameter and medium grade fill, this brush delivers consistent cutting action for rust removal, scale cleaning, paint stripping, and weld spatter cleanup. It is rated to a maximum of 6,000 RPM and includes a 0.25-inch shank for direct chuck mounting on angle grinders and die grinders. The bridled construction keeps the wire fill tightly controlled during operation, reducing flare and maintaining brush geometry over time.\u003c\/p\u003e\u003cp\u003eThis cup brush is suited for use in welding shops, metal fabrication facilities, HVAC ductwork preparation, and general industrial maintenance.
