It features a 21\/64 inch (0.3281 inch) diameter, a 140-degree R-thinned point for accurate self-centering entry, and an EgiAs coating for extended tool life under heat and wear. With a straight-cylindrical shank measuring 3\/8 inch in diameter and a regular spiral flute, this bit delivers consistent chip evacuation and stable cutting action. The overall length is 128.00 mm with a flute length of 67.00 mm, placing it in a 5xD flute-to-diameter ratio. It is intended for licensed machinists and tooling professionals working in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for blind hole drilling, cross-hole operations, and standard through-drilling in steel, alloy steel, cast iron, titanium, and titanium alloys. It supports coolant-through delivery, making it well-matched for CNC machining centers and production drilling applications where thermal management is critical. The two-flute, right-hand cut configuration handles high chip loads typical of these harder workpiece materials. It is part of OSG Series 6510 and is built for applications where standard HSS tooling falls short.\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 and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e140-degree R-thinned point promotes self-centering and reduces thrust force at entry\u003c\/li\u003e\n  \u003cli\u003eEgiAs coating extends tool life in steel, cast iron, titanium, and titanium alloys\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed CNC drilling with active heat management\u003c\/li\u003e\n  \u003cli\u003eTapered web with R-thinned web configuration reduces cutting resistance in deep holes\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders sized for 3\/8 inch shanks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for primary workpiece material codes P (steel), K (cast iron), S (titanium and titanium alloys), and H (hardened materials).

Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Verify the collet or chuck is sized for a 3\/8 inch shank and torqued to the machine manufacturer's specification. When running coolant-through, confirm coolant pressure and flow rate are set per the machining program before initiating the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 21\/64 inch (0.3281 inch \/ 8.33 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\u003ePoint Type\u003c\/strong\u003e: R-Thinned\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\u003eOverall Length\u003c\/strong\u003e: 128.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 67.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.022 mm\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\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\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 651032711\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731097026866,"sku":"651032711","price":340.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36adc2d2617bb4917925c3f830045324_e7e1574b-9fca-4324-9822-650fc873b5b0.jpg?v=1788726897","url":"https:\/\/voomisupply.com\/products\/osg-651032711-solid-carbide-jobber-drill-bit-21-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
