Ground from high speed steel with a bright, uncoated finish, this bit features a 118-degree standard point angle, a web-thinned and tapered web configuration for improved penetration, and a right-hand spiral flute for efficient chip evacuation. The straight-cylindrical shank seats securely in standard drill chucks. At 2.375 inches overall length with a 1.25-inch flute, this compact stub-length bit delivers added rigidity and reduced deflection compared to jobber-length alternatives.\u003c\/p\u003e\u003cp\u003eThis bit is suited for screw machine operations, CNC drilling, and short-reach production drilling tasks in metal fabrication and machining environments. The R41 series is rated for general-purpose use with a high-performance designation, and the ANSI standard compliance ensures dimensional consistency. The 0.209-inch diameter corresponds to wire gauge #4, making it a direct selection for applications requiring precise wire-gauge sizing. Machinists, tool-and-die professionals, and maintenance technicians working with titanium and similar materials will find this bit a practical fit for tight-tolerance bores.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.209-inch diameter, wire gauge #4 sizing for precise bore applications\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with bright, uncoated finish for general-purpose metal drilling\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for improved starting and penetration\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length at 2.375 inches overall — increased rigidity, reduced deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular spiral type for consistent chip removal\u003c\/li\u003e\n\u003cli\u003eANSI-compliant dimensions; R41 series high-performance designation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose screw machine length drill bit in the R41 series, compatible with standard straight-shank drill chucks and screw machine setups requiring a 0.209-inch diameter, wire gauge #4 bore. Primary workpiece material rating includes titanium; suitable for comparable hard and soft metals within the 0.200- to 0.250-inch drill size range per ANSI specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by machinists and tool operators in drill presses, screw machines, or CNC machining centers equipped with standard drill chucks accepting straight-cylindrical shanks. Ensure the machine is powered down and the chuck is fully secured before beginning any bit change. Use appropriate cutting fluid or coolant where workpiece material and machine setup allow, noting this bit does not support coolant-through delivery. Inspect the cutting edges and web for wear before each use to maintain bore quality and bit integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.209 inches (Wire #4)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-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\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.200 to 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R41\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5999405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51709630546226,"sku":"5999405","price":60.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/58769e6c999d5555775cacceeffce019.jpg?v=1788458632","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999405-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
