It measures 0.8906 inches (57\/64 inch) in diameter with a 118-degree standard point angle and a 2-flute regular spiral configuration. The bit is made from high speed steel with an oxide finish that provides light corrosion resistance and reduces friction during cutting. At 5.625 inches overall length with a 3.625-inch flute length, this stub-length design delivers increased rigidity compared to jobber-length bits, making it well suited for use in drill presses, CNC machines, and hand-held power drills where chatter and deflection need to be minimized.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for professional metalworking and fabrication applications where a shorter, stiffer cutting tool is preferred. The straight-cylindrical shank allows it to seat securely in standard drill chucks. The right-hand cut and regular spiral flute geometry promote efficient chip evacuation during through-hole and blind-hole operations. It is commonly used by machinists, maintenance technicians, and fabricators working on production drilling tasks that require a repeatable, tight-tolerance result. The 3xD flute-to-diameter ratio is consistent with screw machine length standards per ANSI specification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e57\/64 inch (0.8906 inch) diameter for precision sizing to standard fractional drill charts\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle suitable for general-purpose drilling across common materials\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides durability and heat resistance at typical drilling speeds\u003c\/li\u003e\n\u003cli\u003eOxide finish reduces surface friction and provides light protection against corrosion\u003c\/li\u003e\n\u003cli\u003eStub screw machine length (5.625 inches overall) increases rigidity and reduces deflection\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard 3-jaw drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose screw machine length drill bit compatible with any drill press, CNC drilling machine, or hand-held power drill equipped with a chuck sized to accept a straight-cylindrical shank at 0.8906 inches diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Secure the shank fully in the chuck before operation and confirm the workpiece is properly clamped or fixtured. Always wear appropriate eye protection and follow applicable machine guarding requirements. Do not exceed the recommended feed rate or surface speed for the material being drilled, and allow the bit to cool or use appropriate cutting fluid to prevent heat buildup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 57\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.8906 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: Oxide\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 61698775\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731997753650,"sku":"61698775","price":117.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e34948515a132ddea86c75b2ac2be80_f53a483e-9c53-4809-9330-538cb7a51681.jpg?v=1788737839","url":"https:\/\/voomisupply.com\/products\/hertel-61698775-screw-machine-drill-bit-57-64-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
