It measures 0.1575 inches (4.00 mm) in diameter with a 140-degree split point and an overall length of approximately 2.60 inches (66.00 mm). The two-flute spiral design paired with R-thinned web geometry reduces thrust and improves chip evacuation. This bit is installed by machinists, tool and die technicians, and metalworking professionals in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is built for use in CNC machining centers, drill presses, and screw machines where compact stub-length tooling is required for precision hole-making. The screw machine length body provides added rigidity compared to jobber-length bits, making it well suited for tight-tolerance bores in steel, alloy steel, and cast iron workpieces. The straight cylindrical shank fits standard collet chucks and drill chucks sized for 4.00 mm shanks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous metals\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with R-thinned web reduces entry thrust and improves centering\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length body provides greater rigidity than jobber-length bits\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral design promotes efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCoated finish extends tool life in steel and alloy steel cutting\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with tapered web configuration for consistent runout\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling steel, alloy steel, and cast iron workpieces; fits standard collet chucks and drill chucks accepting a 4.00 mm straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine at a full stop and all power isolated. Solid carbide tooling is brittle and should be secured with proper collet torque using a calibrated torque wrench to avoid shank slippage or micro-fractures. Inspect the cutting edges and point geometry before each use; discard any bit showing chipping or heel wear. Follow the machine manufacturer guidelines and applicable shop safety codes when setting speeds and feeds for carbide tooling in ferrous materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1575 inches (4.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.60 inches (66.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.94 inches (24.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm straight cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, alloy steel, cast iron\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: 6300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8670400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51746350694706,"sku":"8670400","price":109.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e410708c203bcfb5b50cbd229854823.jpg?v=1788868774","url":"https:\/\/voomisupply.com\/products\/osg-8670400-screw-machine-drill-bit-0-1575-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
