Built to Series 6500 specifications, it features a 6.80 mm diameter, a 140-degree point angle with R-thinned web geometry, and an EgiAs coating designed to extend tool life in demanding production environments. At 88.00 mm overall length with a 34.00 mm flute length, this stub-style bit delivers increased rigidity compared to jobber-length drills. The straight-cylindrical shank measures 7.00 mm in diameter and seats securely in standard drill chucks or collet holders. Coolant-through capability supports high-speed machining applications where heat management is critical.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in CNC machining centers, drill presses, and screw machines where short overall length minimizes deflection and maximizes rigidity. Primary workpiece materials include steel, alloy steel, cast iron, titanium, and titanium alloys. The 3xD flute-to-diameter ratio and regular spiral flute geometry provide efficient chip evacuation in these materials. This bit is intended for use by machinists, tool-and-die professionals, and production shops requiring consistent hole quality and tight diameter tolerances.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and exotic alloy materials\u003c\/li\u003e\n  \u003cli\u003eEgiAs coating extends tool life and reduces friction during high-speed drilling\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle with R-thinned web for reduced thrust force and improved centering\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal coolant delivery for heat management\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length reduces deflection and increases rigidity in short-reach applications\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0 to -0.022 mm for consistent, repeatable hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling steel, alloy steel, cast iron, titanium, and titanium alloy workpieces. The 7.00 mm straight-cylindrical shank is compatible with standard drill chucks and collet systems accepting shanks in the 0.2500 to 0.3000 decimal inch range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with carbide tooling. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the application. When using coolant-through capability, confirm the machine spindle and toolholder support internal coolant delivery before engaging the coolant system. Carbide is brittle — avoid interrupted cuts or side-loading that can cause chipping or breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.80 mm (0.2677 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint 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\u003eOverall Length\u003c\/strong\u003e: 88.00 mm (3.4646 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7.00 mm (0.2756 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool 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\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\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: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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: 6500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.55 x 0.50 x 0.45 inches\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: 8690680\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51738739540274,"sku":"8690680","price":160.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0cc740d9e5a3bb441c080fbcb3db4cec.jpg?v=1788803732","url":"https:\/\/voomisupply.com\/products\/osg-8690680-screw-machine-drill-bit-6-80mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
