Built from high speed steel (HSS) with a bright\/uncoated finish, this bit measures 0.204 inches in diameter (Wire Size 6) and carries an overall length of 2.375 inches with a 1.25-inch flute length. The 118-degree standard point angle and web-thinned, tapered web configuration reduce entry force and improve chip clearance. Licensed machinists, tool and die workers, and HVAC fabrication technicians are the primary installers of this tooling.\u003c\/p\u003e\u003cp\u003eThis bit is suited for screw machine and production drilling operations where a shorter, stiffer tool body minimizes deflection and improves hole accuracy. The Series R41 designation places it in a high-performance HSS lineup built to ANSI standards. Its 2.5xD flute-to-diameter ratio provides efficient chip evacuation. The straight-cylindrical shank fits standard 3-jaw drill chucks found on bench drill presses, CNC drilling centers, and screw machines. The primary workpiece material rating is titanium, though general-purpose use across ferrous and non-ferrous metals is supported.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.204 inch (Wire Size 6) diameter for close-tolerance hole sizing\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction rated for titanium and general-purpose metals\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned tapered web for reduced thrust\u003c\/li\u003e\n\u003cli\u003eScrew machine length body at 2.375 inches overall for improved rigidity\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with 2.5xD ratio for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards, Series R41\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for standard 3-jaw drill chuck setups accepting a straight-cylindrical shank.

Always power down and lock out the drilling machine before changing tooling. Secure the shank fully within the chuck jaws to prevent slippage and runout. Use appropriate cutting fluid when drilling titanium or hardened ferrous materials to extend tool life and maintain hole quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.204 inches (Wire Size 6)\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\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: 5999305\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51699654230322,"sku":"5999305","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7834604261d9ac974935cd54d21416e.jpg?v=1788378751","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999305-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
