The bit measures 0.625 inches in diameter with a 15-inch overall length and an 11-inch flute length, providing the reach needed for through-holes in thick stock or deep cavities that standard-length bits cannot access. A 118-degree point angle and web-thinned, tapered web configuration reduce entry force and help center the bit on the work surface. Right-hand spiral fluting clears chips efficiently during drilling operations. This bit is sized for use in drill presses, CNC machining centers, and heavy-duty hand drills operated by machinists, maintenance mechanics, and metalworking tradespeople.\u003c\/p\u003e\n\u003cp\u003eThe 5999865 is a general-purpose bit in the PRECISION TWIST DRILL Series 1511 and is suited for drilling aluminum, magnesium, copper, nickel, synthetic materials, and titanium as primary workpiece materials. Secondary materials include stainless steel, hardened steel, high strength bronze, nickel alloy, malleable iron, magnesium alloy, and reinforced plastic. The straight-cylindrical shank at 0.625 inches diameter seats securely in standard drill chucks without requiring a reduction sleeve. The uncoated high speed steel construction allows resharpening in the field.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.625 inch diameter with 15-inch overall length for deep-reach drilling\u003c\/li\u003e\n  \u003cli\u003e11-inch flute length handles thick workpieces and stacked material\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust and easier starting\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction — resharpenable and suitable for a broad range of metals and synthetics\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute for consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards; Series 1511 general-purpose grade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use extra length drill bit for general-purpose metalworking and machining operations requiring a 0.625 inch diameter, 15-inch overall length straight-shank bit conforming to ANSI standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified machinists or maintenance mechanics familiar with drill press and rotary tool safety practices. Secure the workpiece firmly before drilling and confirm the chuck is properly tightened onto the straight shank before starting the spindle. Power down and lock out the machine before changing bits or clearing chip buildup. Do not exceed the recommended speed and feed rates for the workpiece material being drilled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\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: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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: 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\u003eSeries\u003c\/strong\u003e: 1511\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\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: 5999865\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51691269816626,"sku":"5999865","price":141.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c5edfec512f0da12b0de14d0e92d81d6.jpg?v=1788282475","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999865-extra-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
