It measures 0.0995 inches (wire gauge 39) in diameter with an overall length of approximately 1.81 inches (46 mm) and a flute length of approximately 0.55 inches (14 mm). The bit features an XPM high-speed steel construction with a coated finish and an X-Thinned web for reduced thrust and improved chip evacuation. The 130-degree split point is suited for self-starting entry without a center punch on most metals. This bit is installed by machinists, tool-and-die professionals, and precision metalworking tradespeople.\u003c\/p\u003e\u003cp\u003eThe OSG 8608253 is used in screw machine operations, CNC drilling, and bench drilling applications where short, rigid tooling is required for accurate hole placement in ferrous and nickel-based materials. The screw machine length geometry provides reduced deflection compared to jobber-length bits, making it well suited for close-tolerance production work on steel and alloy components. Primary workpiece materials include steel, alloy steel, cast iron, and nickel alloy.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eXPM high-performance tool material with coated finish for extended tool life in ferrous metals\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle for reduced thrust and self-centering entry\u003c\/li\u003e\n\u003cli\u003eX-Thinned tapered web reduces cutting resistance and improves chip flow\u003c\/li\u003e\n\u003cli\u003eScrew machine length (3xD flute-to-diameter ratio) for maximum rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral configuration with straight-cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with standard point type; no coolant-through required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill chucks and screw machine spindles accepting a 3.00 mm (approximately 0.118 inches) straight-cylindrical shank; part of OSG Series 1900.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or metalworking professionals. Secure the shank fully in a properly sized drill chuck before operation and verify chuck runout is within acceptable tolerance for the hole size being drilled. Power down and de-energize the machine before changing tooling. Follow applicable shop safety standards and machine manufacturer guidelines for spindle speed and feed rate selection based on workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 39\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0995 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 2.53 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: XPM High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eFlute Length\u003c\/strong\u003e: 14.00 mm (approximately 0.55 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 46.00 mm (approximately 1.81 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm (approximately 0.118 inches)\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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.014 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: 0.013 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: 8608253\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752325841202,"sku":"8608253","price":53.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a6ab825ab7e77d661273cd3a6d350f6.jpg?v=1788927470","url":"https:\/\/voomisupply.com\/products\/osg-8608253-screw-machine-drill-bit-0-0995-in-xpm","provider":"Voomi Supply","version":"1.0","type":"link"}
