Built from high speed steel (HSS) with a bright, uncoated finish, this bit features a 118-degree standard point angle and a right-hand spiral flute for efficient chip evacuation. The straight-cylindrical shank seats securely in standard drill chucks. At 0.173 inches in diameter with an overall length of 2.1875 inches and a flute length of 1.125 inches, this Series R41 bit is sized for precision work in tight clearance situations. The web-thinned, tapered web configuration reduces thrust and improves entry performance on harder workpieces.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for machining shops, tool rooms, and field service work requiring short-length bits with reduced runout risk. The screw machine length profile — shorter than jobber length — provides added rigidity, making it appropriate for CNC drilling, turret lathes, and screw machine applications. The primary workpiece material rating is titanium, though the general-purpose grade supports a range of ferrous and non-ferrous materials. The 2.5xD flute-to-diameter ratio supports controlled chip flow in shallow-to-moderate depth holes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.173 inches (wire size No. 17) diameter for precision hole sizing\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across general-purpose metal drilling\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 adds rigidity over jobber-length alternatives\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant Series R41 construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitment screw machine drill bit for use with straight-shank drill chucks on CNC machining centers, turret lathes, drill presses, and handheld power drills accepting straight-cylindrical shanks.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists and tool room technicians. Secure the straight-cylindrical shank fully into the drill chuck and verify concentricity before operation. Power down and de-energize all equipment before bit changes. Use appropriate cutting fluid or lubricant based on workpiece material to extend tool life and maintain hole quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.173 inches (Wire Size No. 17)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.125 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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\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: 0.04167 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: 5998807\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51723773313330,"sku":"5998807","price":51.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf1477bcc2632bec2263f20fcb2946ae.jpg?v=1788607859","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998807-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
