Built from high speed steel with a coated finish, this bit features a 0.875-inch diameter, a 118-degree standard point angle, and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The straight-cylindrical shank seats securely in standard drill chucks. It is sized for machinists, tool and die technicians, and trade professionals who require repeatable accuracy in short-length drilling applications.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for use in high-performance general-purpose drilling, with titanium listed as the primary workpiece material. The screw machine length body offers a shorter overall profile of 5.5 inches compared to jobber-length bits, providing added rigidity and reduced deflection in tight setups or production drilling scenarios. The 3.5-inch flute length and 2.5xD flute-to-diameter ratio support effective chip clearance across a range of feed rates. It is well suited for use in drill presses, CNC machining centers, and manual milling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.875-inch diameter, screw machine length for increased rigidity and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for improved wear resistance\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web thinning for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards; Series R40 high-performance designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit for applications requiring a 0.875-inch diameter screw machine length bit in straight-cylindrical shank configurations. Primary workpiece material listed as titanium; suitable for general-purpose drilling in applicable setups. Drill bit size range compatibility begins at 0.6000 inches and above per Series R40 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or trade professionals familiar with drill press, CNC, or manual milling equipment. Secure the straight-cylindrical shank firmly in the chuck before operation and verify that spindle speed is appropriate for the workpiece material. Coolant-through is not supported on this bit; apply external cutting fluid as required by the workpiece material and feed rate. Follow applicable shop safety procedures and ANSI machine tool standards during setup and operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.875 inches (7\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.5 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\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\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\u003eSeries\u003c\/strong\u003e: R40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 5998579\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51712724631858,"sku":"5998579","price":90.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6520ef940c4f0deecdf99a74338b685.jpg?v=1788488224","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998579-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
