At 5\/16 inches (0.3125 inches) in diameter, it features a 140-degree drill point angle with R-thinned web geometry that reduces thrust and improves self-centering on entry. The EgiAs coating provides thermal resistance and lubricity, extending tool life in demanding production environments. With an overall length of 118 millimeters and a flute length of 64 millimeters, this bit delivers a 5xD flute-to-diameter ratio suited to blind hole and cross hole operations. Licensed machinists and tool-room technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for use in steel, alloy steel, cast iron, titanium, and titanium alloys, covering ISO material codes P, K, S, and H. It is well suited to CNC machining centers, drill presses, and multi-spindle setups where coolant-through capability can be used to flush chips and manage heat in deep or interrupted cuts. Typical applications include blind hole drilling, cross hole drilling, general drilling, and self-centering starts without a center drill.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard workpiece materials\u003c\/li\u003e\n  \u003cli\u003eEgiAs coating for improved heat resistance and reduced built-up edge\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle with R-thinned web reduces entry thrust and promotes self-centering\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation in blind and deep hole applications\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, 2-flute configuration with tapered web for balanced chip flow\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, alloy steel, cast iron, titanium, and titanium alloys (ISO material codes P, K, S, H).

Secure the shank fully in a collet or drill chuck rated for the required RPM before starting the spindle. When using the coolant-through feature, verify that coolant pressure and flow are established before the tool contacts the workpiece to prevent thermal shock to the carbide. Inspect the cutting edge for chipping before each use, as solid carbide is brittle and should not be used in setups with excessive vibration or unstable workholding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches \/ 7.94 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 118 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 64 mm\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: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 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: R-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: EgiAs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.022 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron, Titanium, Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6510\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Blind Hole, Cross Hole, Drilling, Self-Centering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.8 inches (L) x 0.55 inches (W) x 0.45 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.145 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 651031211\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732539212082,"sku":"651031211","price":231.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4af0f07eb0c5a8c2690e358f7e9f164b.jpg?v=1788744198","url":"https:\/\/voomisupply.com\/products\/osg-651031211-carbide-drill-bit-5-16-inches-140-degree-egias","provider":"Voomi Supply","version":"1.0","type":"link"}
