Measuring 18 inches overall with a 13-inch flute length and a 0.3438-inch diameter, this bit handles demanding production and maintenance drilling tasks. The 118-degree standard point with web thinning reduces entry force and centers the cut without a pilot hole. The bright, uncoated HSS construction is suited for a wide range of workpiece materials. This bit is used by machinists, maintenance technicians, and trade professionals working with metals, plastics, and composites.\u003c\/p\u003e\n\u003cp\u003eThe 5999900 fits applications where extended reach is required, such as drilling through deep structural members, fabrication fixtures, or equipment frames. Its spiral flute design with a regular helix promotes consistent chip evacuation over the full 13-inch flute length. Primary workpiece materials include aluminum, magnesium, copper, nickel, titanium, and synthetic materials. Secondary applications cover stainless steel, steel, malleable iron, nickel alloys, high-strength bronze, and reinforced plastics. The straight-cylindrical shank is compatible with standard drill chucks and collet holders across benchtop and floor-mount drill presses, magnetic drills, and CNC equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-inch overall length with 13-inch flute length for deep-hole reach\u003c\/li\u003e\n  \u003cli\u003e0.3438-inch diameter, 118-degree standard point angle\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction, bright uncoated finish\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral design with regular helix for consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction, ANSI-standard general purpose grade\u003c\/li\u003e\n  \u003cli\u003eSeries 1813 designation, 15xD flute-to-diameter ratio\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard drill chucks and collet systems accepting a 0.3437-inch straight-cylindrical shank.

Power down and de-energize or lock out the drilling equipment before changing bits. Use appropriate cutting fluid or lubricant for the workpiece material to extend tool life and maintain hole quality. Operator should follow applicable shop safety standards and wear appropriate PPE including eye protection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3438 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 13 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3437 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 5 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\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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, Web-Thinned\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: 1813\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: 5999900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51717257953586,"sku":"5999900","price":104.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b0f0fe96d4f1ef330a7fbee73ab4fb96.jpg?v=1788537417","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999900-extra-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
