Built to the SD-3NF industry specification, it features a shear tooth style that produces smooth cuts and reduces chatter during use. The cutting diameter measures 0.375 inches, the length of cut is 0.3125 inches, and the overall length is 2.3125 inches. The 0.25-inch shank mounts directly into standard die grinders and rotary tools. It is rated for a maximum spindle speed of 30,000 RPM. Machinists, toolmakers, and fabricators working with aluminum, brass, copper, and similar materials will find this bur well-suited for deburring, porting, and contouring work.\u003c\/p\u003e\u003cp\u003eThis bur is intended for use on non-ferrous metals, making it a practical choice in fabrication shops, aerospace maintenance environments, and general metalworking applications. The ball profile allows access to curved surfaces, recesses, and contoured bores where flat or cylindrical tools cannot reach. The shear flute geometry reduces material buildup on the cutting edges, which extends working life when cutting softer metals. It fits standard 0.25-inch collet die grinders commonly found in production and maintenance settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBall head shape provides access to curved and recessed surfaces\u003c\/li\u003e\n\u003cli\u003eShear tooth style minimizes chatter and reduces clogging on non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eSolid carbide head construction offers hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eRated to 30,000 RPM for use with high-speed die grinders\u003c\/li\u003e\n\u003cli\u003e0.25-inch shank diameter fits standard collet die grinders and rotary tools\u003c\/li\u003e\n\u003cli\u003eUncoated carbide head — no coating delamination risk during aggressive cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct SD-3NF specification replacement for ball-style carbide burs used on non-ferrous metal applications with 0.25-inch shank die grinders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or toolroom technicians using a standard 0.25-inch collet die grinder or rotary tool.
