Built to Series R40 specifications and conforming to ANSI standards, it features a standard 118-degree point angle, a tapered web with web thinning, and a regular spiral flute configuration. The straight-cylindrical shank seats securely in standard drill chucks. At 3-3\/8 inches overall length with a 2-inch flute length, this stub-length geometry provides added rigidity for accurate hole location. Licensed machinists, tool-and-die technicians, and mechanical contractors reach for this bit when short, stiff drilling action is required.\u003c\/p\u003e\n\u003cp\u003eThe 5998588 is rated for high performance drilling in titanium as its primary workpiece material, though its general-purpose grade and HSS construction also handle a broad range of ferrous and non-ferrous metals encountered in production and maintenance settings. The 2.5xD flute-to-diameter ratio and web-thinned point reduce thrust and improve chip evacuation in shorter-stroke applications. Right-hand cutting direction is standard. No coolant-through capability is present, so external coolant or cutting fluid application is the appropriate approach when heat management is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e27\/64 inch (0.4219 inches) diameter, screw machine (stub) length for enhanced rigidity\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with bright\/uncoated finish\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web thinning for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eTapered web and regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards; Series R40 designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style screw machine length drill bit suitable for use in standard drill presses, milling machines, and hand-held power tools accepting a straight-cylindrical shank.

Ensure the machine spindle and chuck are fully stopped and de-energized before inserting or removing the bit. Secure the shank fully in the chuck to the recommended grip depth to prevent pullout under load. Apply appropriate cutting fluid or external coolant when drilling titanium or other hard metals to manage heat buildup, as this bit does not have coolant-through capability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 27\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.4219 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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: 2.5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium\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: R40\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: 0.083 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: 5998588\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51692869615922,"sku":"5998588","price":19.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0f7aec76a54210fd9537864121216e1.jpg?v=1788304294","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998588-27-64-in-screw-machine-drill","provider":"Voomi Supply","version":"1.0","type":"link"}
