Built to Series R41 specifications, this bit features a 0.086 inch (wire size 44) diameter with a 118-degree standard point angle and a web-thinned, tapered web configuration for improved penetration and reduced thrust. The bright\/uncoated finish suits general-purpose applications. At 1-3\/4 inches overall length with a 3\/4 inch flute length, the shorter-than-jobber body provides added rigidity in screw machine and drill press setups. Machinists, toolroom technicians, and CNC operators handling small-diameter work are the primary users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in screw machines, turret lathes, drill presses, and CNC machining centers where stub-length rigidity is required. The right-hand spiral flute and straight cylindrical shank allow it to seat directly in standard drill chucks and collets. Per the supplier specifications, it is rated for use on titanium as a primary workpiece material, making it appropriate for aerospace, medical, and precision machining operations that demand consistent hole geometry at small diameters. The 2.5xD flute-to-diameter ratio supports chip evacuation in short drilling cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 44 diameter: 0.086 inches for small-bore precision work\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length body at 1-3\/4 inches overall for enhanced rigidity\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for titanium and general-purpose metal cutting\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — no coating buildup to affect tight-tolerance hole sizing\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute with straight cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards; Series R41 designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine length drill bit for standard drill chucks and collets accepting straight cylindrical shanks in screw machines, turret lathes, and drill presses.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists and toolroom technicians in drill press or machine tool spindles. Ensure the spindle and workpiece are fully secured before operation. Use appropriate cutting fluid or coolant when drilling titanium or hard alloys to extend tool life and maintain hole tolerance. Inspect the cutting edges and web for wear before each use; replace when point geometry degrades to avoid oversized or off-axis holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.086 inches (Wire Size 44)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3\/4 inch\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 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: 5999233\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51694980202802,"sku":"5999233","price":36.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fdcb38371ef871104243d4710f977dc2.jpg?v=1788330157","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999233-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
