Built from high speed steel (HSS) with a bright\/uncoated finish, it features a 0.201 inch diameter, a 118-degree standard point angle, and a regular spiral flute with a web-thinned, tapered web configuration. At 2.25 inches overall length with a 1.1875-inch flute length, this stubby-format bit provides added rigidity over jobber-length alternatives, reducing deflection in short-hole drilling operations. It is suited for machinists, toolroom technicians, and production drilling professionals.\u003c\/p\u003e\u003cp\u003eThis bit is rated for use on titanium as the primary workpiece material, making it appropriate for demanding aerospace, medical, and precision machining environments. The straight-cylindrical shank fits standard drill chucks without modification. The screw machine length format is common in CNC machining centers, turret lathes, drill presses, and hand-held operations where chuck clearance or rigidity is a priority. The 2.5xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.201 inch diameter, wire gauge size 7\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web thinning for reduced thrust force\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction rated for titanium and general-purpose metals\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length for increased rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish, right hand cut, regular spiral flute\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 screw machine length drill bit compatible with standard straight-shank drill chucks used in CNC machining centers, drill presses, and turret lathes requiring a 0.201 inch diameter stub-length bit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or toolroom technicians familiar with proper chuck torque and runout inspection procedures. Secure the straight-cylindrical shank fully in the chuck before operation to prevent slippage. Inspect the cutting edges for wear or chipping before each use, particularly when drilling titanium or other work-hardening alloys. Follow all applicable shop safety protocols and machine manufacturer guidelines during setup and drilling operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.201 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Gauge Size\u003c\/strong\u003e: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.1875 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\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\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: 0.04167 pounds\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: 5999312\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51701171880242,"sku":"5999312","price":51.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a432420d976e5b78828873164e353f60.jpg?v=1788399251","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999312-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
