Featuring a 118-degree standard point angle with web thinning for easier penetration, the bit runs a 2-flute regular spiral configuration with a tapered web for efficient chip evacuation. At 15 inches overall length and an 11-inch flute length, this bit reaches deep into structural members, frames, and assemblies where standard-length bits fall short. The straight-cylindrical shank measures 5\/16 inch in diameter and seats securely in conventional drill chucks.\u003c\/p\u003e\n\u003cp\u003eThe 5999862 is suited for shops, field technicians, and tradespeople who need extended reach in tight or deep-bore situations. Primary workpiece materials include aluminum, magnesium, copper, nickel, synthetic materials, and titanium. Secondary applications cover stainless steel, hardened steel, high-strength bronze, nickel alloys, malleable iron, reinforced plastics, and magnesium alloys. The bright uncoated finish makes wear inspection straightforward in the field. This is a general-purpose Series 1511 bit built to ANSI standards, appropriate for right-hand cutting in a standard drill press, hand drill, or magnetic drill setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-inch diameter with 15-inch overall length for deep-reach drilling\u003c\/li\u003e\n  \u003cli\u003e11-inch flute length supports extended chip evacuation in deep bores\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web thinning reduces entry force\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles a wide range of metal and synthetic workpieces\u003c\/li\u003e\n  \u003cli\u003e2-flute regular spiral with tapered web configuration for consistent chip flow\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating to obscure wear or flute condition during inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style general-purpose replacement or supplement for 5\/16-inch straight-shank extra length drill bits in standard 3-jaw chucks and drill press spindles. Compatible with primary workpiece materials including aluminum, magnesium, copper, nickel, synthetic materials, and titanium, with secondary suitability for stainless steel, hardened steel, nickel alloys, and reinforced plastics as noted by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists, millwrights, pipefitters, and general trade technicians using standard drill presses, hand drills, or magnetic base drills. Secure the straight-cylindrical shank fully in the chuck before operation and verify runout before drilling into hardened or stainless materials. Use appropriate cutting fluid for ferrous and high-strength workpieces to extend tool life. Follow applicable shop safety and ANSI machining standards when operating at depth with extended-length tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered with Web Thinning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 15xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1511\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5999862\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51709990175026,"sku":"5999862","price":84.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c659693317a6e5a765ad4387c7feafa7.jpg?v=1788462890","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999862-extra-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
