Built from solid carbide and finished with an EgiAs coating, it delivers superior wear resistance and heat management in demanding production environments. The bit features a 180-degree web-thinned point that reduces thrust force and improves centering accuracy at entry. With a 3.50 mm diameter, a 55 mm overall length, and a 16 mm flute length, this stub-length drill is suited for CNC machining centers, drill presses, and screw machines where rigidity and precision matter most. It is sold as a single-piece unit.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for production machining applications where tight tolerances and consistent hole quality are required. The straight-cylindrical shank with a 6 mm diameter allows direct chuck mounting without adapters on standard tooling. The 2xD flute-to-diameter ratio and regular spiral flute geometry support efficient chip evacuation in short-depth holes through steel and cast iron workpieces. Machinists and tool-and-die professionals working in job shops, production facilities, or maintenance operations will find this bit fits standard screw machine and CNC setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eEgiAs coating improves surface hardness and reduces friction during cutting\u003c\/li\u003e\n\u003cli\u003e180-degree web-thinned point reduces entry thrust and improves hole location\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length provides added rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with tapered web configuration supports consistent chip flow\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets without modification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe OSG 3330350 is rated for primary workpiece materials including steel, alloy steel, and cast iron. It is part of OSG Series 5700 and falls within the 3.50 mm to 5.00 mm drill bit size range family.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit should be installed and used by qualified machinists familiar with carbide tooling practices. Secure the shank fully in the chuck or collet to the recommended grip depth before running the spindle. Carbide is brittle — avoid side loading, interrupted cuts without proper feed control, or dropping the tool on hard surfaces. Always confirm spindle speed and feed rate are appropriate for the workpiece material and bit diameter before cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.50 mm (0.1378 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 55 mm (2.1654 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 16 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm (0.2362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 180 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\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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: Web-Thinned\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 2xD\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.043 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: 3330350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51754716823858,"sku":"3330350","price":115.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9461e8ad968568c9c6ff558aab4eb564.jpg?v=1788948053","url":"https:\/\/voomisupply.com\/products\/osg-3330350-screw-machine-drill-bit-3-50-mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
