Built to DIN 6537 specifications, it features a 23\/64-inch (0.2992 inch) diameter, a 135-degree split point, and a Ti-NAMITE-X coating that extends tool life in demanding applications. The straight-cylindrical shank measures 0.390 inches in diameter, and the overall length is 3.5 inches. With a web-thinned point and 4-margin geometry, this bit delivers improved centering accuracy and reduced thrust load. It is intended for use by machinists, tool and die technicians, and maintenance professionals working with precision drilling operations.\u003c\/p\u003e\n\u003cp\u003eThe SGS 66446 is suited for production and maintenance drilling in shop and field environments where a short, rigid drill profile is required. The screw machine length design minimizes deflection, making it well-suited for close-tolerance work on CNC machining centers, drill presses, and manual machines. It is rated for universal workpiece materials, meaning it performs across ferrous metals, non-ferrous metals, and many alloys. The coolant-through design supports internal coolant delivery when used in compatible tool holders, which helps manage heat and chip evacuation at higher feed rates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTi-NAMITE-X coating for extended tool life in high-performance applications\u003c\/li\u003e\n  \u003cli\u003e135-degree web-thinned split point for accurate starting and reduced thrust\u003c\/li\u003e\n  \u003cli\u003e4-margin geometry improves hole straightness and finish quality\u003c\/li\u003e\n  \u003cli\u003eCoolant-through capability supports internal coolant delivery\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537 specification for consistent dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production drill bit for use in standard straight-shank tool holders and chucks accepting a 0.390-inch shank diameter.
