It measures 3.50 mm (0.1378 inches) in diameter with an overall length of 52.00 mm (approximately 2.047 inches) and a flute length of 20.00 mm (approximately 0.787 inches). The bit is manufactured from XPM high-speed steel with a coated finish to extend tool life and reduce friction under load. A 130-degree drill point angle and x-thinned web geometry improve penetration and reduce thrust in hard ferrous materials. This bit is installed by machinists, tool and die professionals, and maintenance technicians working with metalworking equipment.\u003c\/p\u003e\n\u003cp\u003eThe OSG 9599035 is suited for screw machine and production drilling applications where a compact, stub-length bit is required for rigidity and accuracy. Its 3xD flute-to-diameter ratio and straight-cylindrical shank with a 4.00 mm (0.157 inches) shank diameter make it compatible with standard drill chucks and collet holders on CNC machines, drill presses, and screw machines. Primary workpiece materials include steel, alloy steel, cast iron, and nickel alloy. The regular spiral flute and tapered web configuration support efficient chip evacuation in these materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eXPM high-speed steel construction with coated finish for extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e130-degree drill point angle optimized for harder workpiece materials including alloy steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eX-thinned web reduces drilling thrust and improves centering on entry\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides added rigidity and reduced deflection versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders without adapters\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute with tapered web for consistent chip flow\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, alloy steel, cast iron, and nickel alloy workpieces. Part of the OSG Series 1900 screw machine length drill line. Diameter tolerance is +0 to -0.018 mm, placing this bit in the 0.1000 to 0.1500 decimal inch size range for Series 1900.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a drill press, CNC machining center, or automatic screw machine using a chuck or collet sized for a 4.00 mm straight-cylindrical shank. Ensure the workpiece is securely fixtured and the machine spindle is at a full stop before changing bits. No coolant-through capability is present on this bit, so apply cutting fluid externally when drilling harder alloys to manage heat buildup. Inspect the cutting edges and web condition before each use and replace the bit when point geometry shows wear to maintain dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1378 inches (3.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 52.00 mm (approximately 2.047 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 20.00 mm (approximately 0.787 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm (0.157 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: X-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: XPM 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron, Nickel Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.018 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1900\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9599035\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732483703090,"sku":"9599035","price":38.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88d77d51f2468a421582b818299a8a2a.jpg?v=1788743472","url":"https:\/\/voomisupply.com\/products\/osg-9599035-screw-machine-drill-bit-0-1378-in-xpm","provider":"Voomi Supply","version":"1.0","type":"link"}
