It measures 0.0785 inches in diameter with an overall length of 1-11\/16 inches and a flute length of 11\/16 inches. The 118-degree standard point angle and web-thinned, tapered web configuration reduce entry force and improve chip evacuation. The bright, uncoated HSS construction suits general-purpose drilling across a range of ferrous and non-ferrous materials. This bit is part of the R41 series and conforms to ANSI standards. Machinists, toolroom technicians, and precision fabricators install it in drill presses, CNC machining centers, and turret lathes where a short, rigid drill length improves accuracy and reduces deflection.\u003c\/p\u003e\n\u003cp\u003eThe 5999245 is suited for production and job-shop environments requiring consistent hole quality at small diameters. The screw machine length body provides a stiffer, more controlled cut compared to jobber-length bits, making it a common choice for work in metal fixtures, close-tolerance bores, and secondary operations on machined components. The primary workpiece material designation is titanium, though the general-purpose HSS construction also handles a range of other materials. A regular spiral flute and straight cylindrical shank allow straightforward chuck mounting without special toolholding.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0785 inches diameter, wire gauge size #47\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body at 1-11\/16 inches overall for improved rigidity and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction, bright\/uncoated finish for general-purpose use\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank for standard three-jaw chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI standards; R41 series, 2.5xD flute-to-diameter ratio\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose screw machine length drill bit compatible with standard three-jaw drill chucks and collet systems accepting straight cylindrical shanks at 0.0785 inches diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians. Secure the shank fully in a properly sized chuck or collet before operation and verify runout before drilling. Power down the machine and lock out energy sources before changing or inspecting the bit. Do not exceed the spindle speed range appropriate for HSS tooling at this diameter in 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: 0.0785 inches (Wire Gauge #47)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11\/16 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, 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R41\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: 0.04167 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: 5999245\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51692443861298,"sku":"5999245","price":38.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2980f14046102f6db6b115627df59984.jpg?v=1788297566","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999245-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
