Built from high speed steel with a bright, uncoated finish, it measures 1.1875 inches in diameter and 12 inches in overall length. The spiral flute geometry and web-thinned, tapered web configuration help clear chips efficiently while reducing thrust during entry. The 118-degree standard point angle suits a broad spectrum of workpiece materials, making this bit a reliable choice for machinists, fabricators, and industrial maintenance technicians who need a longer reach than a jobber-length bit provides without moving to a full extended-length tool.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in machine shops, fabrication facilities, and maintenance environments where taper length reach is required. It is appropriate for use in drill presses, lathes, and CNC drilling operations. The straight shank fits standard drill chucks without adapters. Its general-purpose grade and ANSI-compliant construction make it compatible with production and repair drilling operations across metals and select non-metallic materials. The 6xD flute-length-to-diameter ratio supports deeper hole applications compared to standard jobber-length bits while maintaining adequate flute volume for chip evacuation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.1875-inch diameter with 12-inch overall length for extended reach drilling\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a wide material range\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry and centering\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web design reduces cutting thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute cut with 7.375-inch flute length\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant Series R51 construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSuitable for drilling alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, cermet, copper, graphite, hardened steel, high strength bronze, magnesium, magnesium alloy, malleable iron, nickel, nickel alloy, reinforced plastic materials, and stainless steel.

Secure the straight shank firmly in a drill chuck before operation and verify chuck runout is within acceptable limits for the hole tolerance required. Always wear appropriate eye protection and follow applicable shop safety procedures when operating rotary cutting tools. Do not exceed the recommended feed rate for the workpiece material, as excessive force can cause bit deflection or breakage at this diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.1875 inches (1-3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7.375 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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.1875 inches\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 Length to Diameter Ratio\u003c\/strong\u003e: 6xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\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: 5999004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51702479913266,"sku":"5999004","price":245.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8e0ea365607c2ee7d7bed857b4304f4.jpg?v=1788411274","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999004-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
