Built from high speed steel with a coated finish, this bit features a 0.9062-inch diameter, a 118-degree standard drill point angle, and a right-hand spiral flute configuration. The straight-cylindrical shank seats securely in standard drill chucks. Web thinning reduces thrust at the point and improves chip evacuation, making it well-suited for production drilling environments where speed and hole quality matter. It is installed by machinists, maintenance technicians, and fabrication professionals.\u003c\/p\u003e\n\u003cp\u003eThe 5998624 is rated for drilling titanium as its primary workpiece material, which also indicates suitability for other tough metals in comparable hardness ranges. The screw machine length format — shorter overall length than jobber bits — provides added rigidity and reduced deflection, which is particularly valuable when drilling deep or working in tight setups. With a flute-to-diameter ratio of 2.5xD and a 3.625-inch flute length, it balances chip clearance with structural stiffness. This bit fits applications in HVAC equipment fabrication, plumbing fixture manufacturing, and general mechanical assembly where precision hole sizing is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.9062-inch (29\/32 inch) diameter for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web thinning for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n  \u003cli\u003eScrew machine length provides added rigidity over standard jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine length drill bit for standard straight-shank drill chucks and holders rated for bits in the 0.6000-inch diameter and above range, per ANSI standards.

Secure the shank fully in a drill chuck or holder before operation and verify runout before drilling. Disengage all power and lock out the machine before changing bits or making chuck adjustments. Follow applicable shop safety protocols and manufacturer feed-and-speed guidelines 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: 0.9062 inches (29\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.625 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: Coated\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, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium\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: 0.5 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: 5998624\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693193920818,"sku":"5998624","price":88.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae0e66632e10a1ff56ab6c17e31cf254.jpg?v=1788308727","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998624-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
