At 0.5313 inches in diameter with a 15-inch overall length and an 11-inch spiral flute, it reaches depths that standard-length bits cannot. The 118-degree standard point angle and web-thinned tip reduce entry force and help keep the bit on center at the start of the cut. The bright, uncoated finish is the baseline choice when cutting fluids or coatings are not required. This bit is sold individually and suits machinists, maintenance technicians, and fabricators who need reliable material removal in extended-reach applications.\u003c\/p\u003e\u003cp\u003eThe 5999833 is built for drilling aluminum, magnesium, copper, nickel, titanium, and synthetic materials as primary workpiece targets. It also handles secondary materials including stainless steel, malleable iron, nickel alloys, high strength bronze, hardened steel, reinforced plastics, and magnesium alloys. The straight-cylindrical shank at 0.5313 inches diameter and 4 inches in length fits standard drill chucks without an adapter. The right-hand, regular spiral with a tapered web configuration suits general purpose production and maintenance drilling where flute-to-diameter ratio matters  -  this bit runs at 15xD.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.5313 inch diameter with matching straight-cylindrical shank for direct chuck mounting\u003c\/li\u003e\n\u003cli\u003e15-inch overall length and 11-inch flute length for deep-hole reach\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry force\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction  -  bright, uncoated finish suitable for use with cutting fluid\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral with 2 flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards; Series 1511 general purpose grade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general purpose extra length drill bit compatible with primary workpiece materials including aluminum, magnesium, copper, nickel, titanium, and synthetic materials, as well as secondary materials such as stainless steel, hardened steel, malleable iron, nickel alloys, high strength bronze, reinforced plastics, and magnesium alloys.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and operate this bit using a drill press, milling machine, or powered hand drill with a chuck rated for a 0.5313-inch straight shank. Secure the shank fully in the chuck and verify concentricity before drilling to prevent deflection at extended lengths. Always wear appropriate eye protection and secure the workpiece before engaging the spindle. Apply cutting fluid when drilling ferrous or hard alloy materials to extend tool life and manage heat.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5313 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: 0.5313 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\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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 by Diameter Ratio\u003c\/strong\u003e: 15xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5999833\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":67662673117490,"sku":"5999833","price":143.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/013cc2d01e9bb1b32f44690995c88d48.jpg?v=1790470500","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999833-extra-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
