Built from high speed steel with a bright\/uncoated finish, it features a standard 118-degree point angle and a web-thinned, tapered web configuration that improves centering and reduces thrust on entry. The spiral flute design promotes chip evacuation during through-hole and deep drilling operations. At 5.75 inches overall length with a 3.375-inch flute, this bit provides extra reach compared to a jobber-length drill, making it well suited for applications where standard-length bits fall short. It is installed by machinists, maintenance technicians, pipefitters, and HVAC fabricators working on sheet metal, structural components, and mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThe 5999688 is a Series R51 taper length drill intended for use in drill presses, CNC machines, and hand-held power drills with a standard 3-jaw chuck. Its straight shank and 11\/64 inch shank diameter allow direct chuck mounting without adapters. The bit is suited for drilling alloy steel, carbon steel, stainless steel, cast iron, malleable iron, aluminum, aluminum alloy, brass, bronze, copper, magnesium, nickel, nickel alloy, high strength bronze, cermet, graphite, reinforced plastic materials, and hardened steel. It conforms to ANSI standards and is rated for general-purpose performance across production and maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e11\/64 inch (0.1719 inches) diameter with matching straight shank for direct chuck mounting\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles a broad range of ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for improved centering and reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eTaper length body at 5.75 inches overall provides extended reach beyond jobber-length drills\u003c\/li\u003e\n  \u003cli\u003eSpiral flute with 6xD flute-to-diameter ratio promotes efficient chip clearance in deeper holes\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish; right-hand cut; conforms to ANSI standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose taper length drill bit compatible with any standard 3-jaw drill chuck or collet system accepting an 11\/64 inch straight shank.

Ensure the workpiece is firmly secured and the machine is at a full stop before inserting or removing the bit. Select an appropriate cutting speed and feed rate for the workpiece material to avoid overheating the uncoated high speed steel. Coolant-through is not supported on this bit; use a cutting fluid applied externally when drilling harder ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 11\/64 inch (0.1719 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 11\/64 inch (0.1719 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\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\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\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\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\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 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: 5999688\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51710431559986,"sku":"5999688","price":19.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c51c10a47c5868d2032eda4943925ba.jpg?v=1788466867","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999688-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
