Manufactured from high speed steel with a coated finish, this bit measures 0.9688 inches (31\/32 inch) in diameter and cuts in a right-hand direction with a standard 118-degree point angle. The spiral flute design and web-thinned, tapered web construction reduce thrust and improve chip evacuation. At 5-7\/8 inches overall length with a 3-7\/8 inch flute length, it fits standard straight-cylindrical shank chucks and drill presses used by machinists and fabricators.\u003c\/p\u003e\n\u003cp\u003eThis Series R40 bit is built for screw machine length applications where a shorter, stiffer profile improves accuracy and reduces deflection in production drilling setups. It is rated for use on titanium as its primary workpiece material, making it well suited for aerospace, industrial maintenance, and precision fabrication environments. The 2.5xD flute-to-diameter ratio supports chip clearing in moderate-depth holes. It meets ANSI standards and is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.9688 inch (31\/32 inch) diameter with 118-degree standard point angle\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces entry thrust and improves cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eScrew machine length profile provides added rigidity over jobber length bits\u003c\/li\u003e\n  \u003cli\u003eSpiral flute, right-hand cut for standard drill press and CNC lathe use\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 a screw machine length replacement or production drill bit compatible with straight-cylindrical shank drill chucks.

Secure the straight-cylindrical shank fully in a properly sized chuck before operation. Always power down and lock out the machine before changing or inspecting tooling. Do not exceed the recommended feed and speed parameters 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: 0.9688 inches (31\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-7\/8 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 5998481\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51689277358386,"sku":"5998481","price":105.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9a2f2c6ba37556ab3bb6dd6a20cb8c6.jpg?v=1788256659","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998481-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
