Built from high speed steel with a coated finish, this bit measures 0.209 inches (wire gauge #4) in diameter with an overall length of 2-3\/8 inches and a flute length of 1-1\/4 inches. The 135-degree split point reduces walking and allows faster penetration without a center punch. Web thinning further reduces thrust requirements, making this bit well suited for precision work in harder materials.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for primary use in titanium and is appropriate for heavy-duty machining and fabrication environments. The screw machine length format — shorter than jobber length — provides greater rigidity and improved accuracy in drill press, CNC, and turret lathe setups. It is commonly used by machinists, maintenance technicians, and fabricators who require tight-tolerance hole production in metals. The straight-cylindrical shank fits standard drill chucks without adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces drill walking and lowers required feed force\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction reduces thrust and improves chip evacuation\u003c\/li\u003e\n  \u003cli\u003eScrew machine length provides added rigidity over jobber-length bits in tight setups\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for wear resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for standard drilling operations\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 standards; Series R41C heavy-duty grade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use bit for standard drill chucks accepting straight-cylindrical shanks; fits drill presses, CNC machining centers, and turret lathes configured for screw machine length tooling.

Ensure the machine spindle is fully stopped and the chuck is properly tightened before beginning any drilling operation. Use appropriate cutting fluid or coolant when drilling titanium and other hard metals to extend tool life and maintain hole quality. Inspect the cutting edges for wear or chipping before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2090 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: #4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\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\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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: R41C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 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: 5998583\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51715971907890,"sku":"5998583","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/62a5629a00cc461a1b205a8a7d1f7328.jpg?v=1788520409","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998583-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
