It measures 0.2598 inches (6.60 mm) in diameter with an overall length of 70.00 mm and a flute length of 30.00 mm. The 180-degree drill point angle delivers a flat-entry cut suited for flat-bottomed hole applications, while the web-thinned, tapered web configuration reduces thrust and improves chip evacuation. Two spiral flutes with a right-hand cutting direction handle chip removal efficiently. This bit belongs to OSG Series 5700 and is intended for installation by machinists, tool-and-die professionals, and maintenance technicians working in precision metal fabrication environments.\u003c\/p\u003e\n\u003cp\u003eThe OSG 3330660 is suited for drilling steel, alloy steel, and cast iron in screw machine operations and general production drilling where short, rigid tooling is required. The screw machine length geometry provides greater rigidity than jobber-length bits, making it appropriate for use in CNC machining centers, drill presses, and turret lathes where tight tolerances and consistent hole quality are critical. The 2xD flute-to-diameter ratio is optimized for shallow-hole applications where rapid chip clearance is a priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life in ferrous workpiece materials\u003c\/li\u003e\n  \u003cli\u003e180-degree flat drill point angle for flat-bottomed hole entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces cutting thrust and improves penetration\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body provides added rigidity over jobber-length alternatives\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute design with 2xD flute-to-diameter ratio for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with 6.00 mm shank diameter fits standard drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with steel, alloy steel, and cast iron workpieces. Compatible with standard straight-shank drill chucks and ER collet systems accepting a 6.00 mm shank. Drill bit diameter falls within the 0.2500 to 0.3000 inch (6.50 to 8.00 mm) size range of OSG Series 5700.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified machinists or tooling professionals familiar with carbide cutting tool handling. Secure the straight-cylindrical shank firmly in a drill chuck or collet before use and verify runout is within acceptable limits for the application. Solid carbide tooling is brittle and susceptible to breakage from side-loading, cross-drilling, or interrupted cuts at improper feed rates. Power down and de-energize the machine spindle fully before changing or inspecting the bit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2598 inches (6.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 180 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 70.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 30.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm\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: Coated\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: 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 Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 2xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron\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 -0.022 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5700\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\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: 3330660\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730833244466,"sku":"3330660","price":167.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6610b5b7e64749449347a1ca53a6449c_b21489af-af3f-484a-b054-cd93fe1289f1.jpg?v=1788723575","url":"https:\/\/voomisupply.com\/products\/osg-3330660-screw-machine-drill-bit-0-2598-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
