It features a 0.266 inch (17\/64 inch, Letter H) diameter, a 135-degree split point, and a bright uncoated finish. The two-flute spiral design with slow spiral geometry and a tapered web configuration supports controlled chip evacuation and stable cutting performance. Web thinning reduces entry force and improves hole quality. This bit is intended for use by machinists and tool and die professionals working with CNC equipment, drill presses, and manual lathes.\u003c\/p\u003e\u003cp\u003eThe 215-2660 is suited for drilling steel, alloy steel, stainless steel, cast iron, aluminum silicate, nickel alloy, titanium, and titanium alloy. Its screw machine (stub) length body provides added rigidity compared to jobber-length bits, making it a practical choice for short-reach applications where runout control and rigidity matter. The straight cylindrical shank fits standard drill chucks and collet holders without modification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for hardness and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e135-degree standard point angle with web thinning for reduced thrust and cleaner entry\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute geometry promotes chip control in tough alloys\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general-purpose use across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eTapered web configuration adds rigidity and helps maintain concentricity during drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose solid carbide screw machine drill bit in OSG Series 215, suitable for use in CNC machining centers, drill presses, and manual lathes drilling steel, stainless steel, cast iron, nickel alloy, titanium, and similar materials.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\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 tolerances. Carbide tooling is brittle — avoid lateral loading, interrupted cuts without proper feed adjustment, and dropping the bit on hard surfaces. Follow machine manufacturer guidelines for feed and speed settings appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.266 inches (17\/64 inch, Letter H, 6.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 135 degrees\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: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Slow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.5 inches (38.10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.688 inches (2-11\/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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.013 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Alloy Steel, Stainless Steel, Cast Iron, Aluminum Silicate, Nickel Alloy, Titanium, Titanium Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 215\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: 215-2660\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51749131026738,"sku":"215-2660","price":78.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc79d7e56f65ddd330843dd4ffa929b9.jpg?v=1788902410","url":"https:\/\/voomisupply.com\/products\/osg-215-2660-carbide-screw-machine-drill-bit-0-266-in","provider":"Voomi Supply","version":"1.0","type":"link"}
