Built to industry specification SD-5, it features a 1\/2-inch cutting diameter and a 1\/4-inch shank diameter. The single-cut tooth style provides controlled material removal with reduced chatter, making it well suited for ferrous and non-ferrous metals, hardened steel, and cast iron. Licensed machinists, tool-and-die makers, and skilled tradespeople use this bur with die grinders and rotary tools for precision finishing work.\u003c\/p\u003e\n\u003cp\u003eThis bur is appropriate for use in industrial, manufacturing, and heavy fabrication environments where consistent stock removal and surface refinement are required. The ball profile is particularly effective for concave surface blending, port matching, and weld cleanup in tight or curved geometries. It is sold individually and ships in a single-piece package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBall head shape for concave surface work, port matching, and weld cleanup\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides hardness and wear resistance compared to high-speed steel alternatives\u003c\/li\u003e\n  \u003cli\u003eSingle-cut tooth style for smooth, controlled material removal\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch shank fits standard die grinder and rotary tool collets\u003c\/li\u003e\n  \u003cli\u003eUncoated head — no coating delamination risk in high-heat applications\u003c\/li\u003e\n  \u003cli\u003eMeets industry specification SD-5\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with die grinders and rotary tools accepting a 1\/4-inch shank collet.
