The bit measures 0.3906 inches in diameter with an 18-inch overall length and a 13-inch spiral flute, providing the clearance and chip evacuation needed when boring into thick stock or deep cavities. The 118-degree standard point and web-thinned geometry reduce entry force and improve centering on the workpiece. With a bright, uncoated finish and a straight-cylindrical shank, this bit seats securely in conventional drill chucks and spindles. It is used by machinists, pipefitters, and maintenance mechanics who need a reliable general-purpose bit for production or field work.\u003c\/p\u003e\n\u003cp\u003eThe 5999957 is suited for drilling into aluminum, magnesium, copper, nickel, synthetic materials, and titanium as primary workpiece materials. Secondary materials include stainless steel, hardened steel, high strength bronze, nickel alloys, malleable iron, reinforced plastics, and steel. The 15xD flute-to-diameter ratio and tapered web configuration support consistent chip flow in deeper cuts. Right-hand cutting direction is standard. This bit is appropriate for use in drill presses, milling machines, and hand-held power tools where a straight-shank extra-length bit is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-inch overall length and 13-inch flute length for deep-reach drilling applications\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust and improved starts\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish compatible with cutting fluids and oils\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eTwo-flute spiral design with regular spiral type for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eANSI standard compliance for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose extra length drill bit compatible with standard drill chucks and spindles accepting a 0.3906-inch straight-cylindrical shank.

Secure the straight-cylindrical shank fully into the chuck before operation and verify runout before beginning the cut. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain dimensional accuracy. Inspect the cutting edges for wear or chipping before each use, and never force a dull bit through material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3906 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: 0.3906 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\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 15xD\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: 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: 5999957\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51695443476786,"sku":"5999957","price":108.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b0662d042f1fce864eaa73efdc7a69cc.jpg?v=1788335073","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999957-extra-length-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
