This ball-shaped point (shape code B90) features a 60-grit, medium-grade abrasive that removes material efficiently while maintaining control in confined areas. The pink aluminum oxide grain is well-suited for ferrous metals and general-purpose tool room work. With a 0.125-inch shank diameter and a rated maximum speed of 34,500 RPM, it is sized for use in standard die grinders, rotary tools, and high-speed spindle machines operated by machinists, tool-and-die workers, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis mounted point is used in applications requiring access to tight cavities, ports, bores, and complex contours that larger abrasive tools cannot reach. Common applications include weld cleanup, mold and die finishing, porting, and deburring of cast or machined components. The ball shape allows contact with curved and concave surfaces. It is appropriate for both production shop and bench work environments where a small, consistent abrasive point is required for detail grinding on metal workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBall shape (B90) contacts curved, concave, and recessed surfaces\u003c\/li\u003e\n  \u003cli\u003e60-grit medium-grade aluminum oxide abrasive for efficient stock removal\u003c\/li\u003e\n  \u003cli\u003eRated to 34,500 RPM for use with standard die grinders and rotary tools\u003c\/li\u003e\n  \u003cli\u003e0.125-inch shank diameter fits common collet sizes on rotary and die grinding equipment\u003c\/li\u003e\n  \u003cli\u003ePink aluminum oxide grain suited for ferrous metal grinding and general tool room use\u003c\/li\u003e\n  \u003cli\u003eCompact 0.5-inch head thickness for access to tight areas and fine detail work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard mounted point for die grinders, rotary tools, and high-speed spindle machines accepting a 0.125-inch shank.
