It measures 0.147 inches in diameter (Wire Size 26, 3.73 mm) with a 130-degree split point and a straight-cylindrical shank. The screw machine length format provides a short, rigid profile that reduces deflection and improves hole location accuracy. With a 2-flute spiral configuration and X-thinned web, this bit delivers clean entry and efficient chip evacuation in production and maintenance drilling applications. Licensed trades and metalworking shops rely on this geometry for consistent performance in tight-tolerance work.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use in CNC machining centers, drill presses, and hand-held power drills where a stub-length bit is preferred for rigidity. Primary target materials are steel and alloy steel. The screw machine (stub) length makes it a practical choice for confined drilling locations or applications where a standard-length bit would introduce chatter or walkoff. It is sold individually and is compatible with standard drill chucks accepting straight cylindrical shanks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high speed steel construction for elevated heat and wear resistance in steel drilling\u003c\/li\u003e\n\u003cli\u003e130-degree point angle with X-thinned web for positive engagement and reduced thrust\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length profile increases rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003e2-flute spiral design promotes efficient chip removal\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard keyed and keyless drill chucks\u003c\/li\u003e\n\u003cli\u003eTapered web configuration enhances core strength along the flute length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine length drill bit for use in standard drill chucks accepting straight-cylindrical shanks; primary workpiece materials are steel and alloy steel as specified by the manufacturer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by machinists, maintenance technicians, or qualified tradespeople familiar with rotating cutting tools. Secure the shank fully in the chuck and verify concentricity before drilling. Always operate within the spindle speed and feed rate range appropriate for the workpiece material and bit diameter. Wear appropriate eye protection and ensure the workpiece is firmly clamped before beginning any drilling operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.147 inches (3.73 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 26\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch (25 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Coated\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, X-Thinned Web\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel\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\u003eSeries\u003c\/strong\u003e: 1000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.017 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: 10147005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730034196786,"sku":"10147005","price":41.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2fc7f582d41a42b1fdf236ad8e1079c5.jpg?v=1788710528","url":"https:\/\/voomisupply.com\/products\/osg-10147005-cobalt-hss-screw-machine-drill-bit-0-147-in","provider":"Voomi Supply","version":"1.0","type":"link"}
