Built from solid carbide and finished with OSG's proprietary EgiAs multi-layer coating, this bit is engineered for demanding production environments where tool life and hole quality are critical. It features a 180-degree flat bottom point, web-thinned geometry for reduced thrust, and a 3xD flute-to-diameter ratio. The straight cylindrical shank measures 4.00 mm in diameter, and the overall length is 55.00 mm (2.17 inches). Coolant-through capability supports high-speed machining operations. This bit is installed by machinists and toolroom professionals working with CNC or manual screw machine setups.\u003c\/p\u003e\u003cp\u003eThe OSG 3334304 is suited for screw machine length drilling applications in production and job-shop environments. Its compact stub length improves rigidity and reduces deflection in short-hole drilling operations. Primary target materials include steel, cast iron, and hardened workpieces where a standard high-speed steel bit would underperform. The flat bottom point geometry also makes it appropriate for flat-bottomed or stepped-hole applications. The Series 5720 designation places it within OSG's line of solid carbide screw machine drills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eEgiAs proprietary multi-layer coating reduces friction and improves wear resistance\u003c\/li\u003e\n\u003cli\u003e180-degree flat bottom point eliminates the center point, supporting flat-bottomed holes\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration reduces entry thrust and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed and high-feed rate drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting with regular spiral flute for consistent chip flow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine length drill bit for use in CNC machining centers, screw machines, and drill presses where a straight cylindrical shank and stub-length geometry are required for steel, cast iron, and hardened material applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit is installed by machinists and toolroom technicians in CNC or manual machine tool setups. Ensure the machine spindle and tool holder are clean and free of runout before seating the straight shank. Verify that the machine's coolant-through system is compatible and active before high-speed operation. Do not exceed the drill's rated feed and speed parameters for the target workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.20 mm (0.1260 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 55.00 mm (2.1654 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 15.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm (0.1575 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\u003ePoint Type\u003c\/strong\u003e: Flat Bottom\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 Multi-layer\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: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Cast Iron, Hardened Materials\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: 5720\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 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: 3334304\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51729960599858,"sku":"3334304","price":146.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1009c2e4540f28444916b42e80c3ac5.jpg?v=1788709994","url":"https:\/\/voomisupply.com\/products\/osg-3334304-screw-machine-drill-bit-3-20mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
