With a 2.90 mm diameter and a 180-degree flat bottom point, this bit delivers precise, flat-bottomed holes suited to tight-tolerance machining applications. The proprietary EgiAs multi-layer coating reduces friction and extends tool life when cutting through tough workpiece materials. At 50.00 mm overall length and a 4.00 mm straight cylindrical shank, this is a compact, rigid tool built for stability in short-reach drilling operations. Installation and use are handled by machinists and toolroom professionals in CNC and conventional drill press setups.\u003c\/p\u003e\u003cp\u003eThis drill bit is engineered for cutting steel, cast iron, and hardened materials in screw machine length configurations. The 2xD flute-to-diameter ratio and web-thinned, tapered web geometry reduce thrust force and improve chip evacuation in shallow-to-moderate depth holes. It is best suited for high-cycle production drilling where tool life and hole quality are priorities. The right-hand cutting direction and regular spiral flute are standard for conventional spindle rotation. Coolant-through capability is not available on this bit, so external coolant or flood cooling should be used as appropriate for the workpiece material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003e180-degree flat bottom point geometry for precise flat-bottomed hole entry and exit\u003c\/li\u003e\n\u003cli\u003eEgiAs proprietary multi-layer coating reduces heat buildup and extends tool life\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers cutting thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with 4.00 mm diameter fits standard collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eSeries 5700 high-performance designation for demanding production applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine length drill bit compatible with standard straight-shank toolholders, collet chucks, and drill press spindles accepting a 4.00 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the machine powered down and the spindle fully stopped. Ensure the shank is fully seated and securely clamped in the toolholder before operation. External coolant or cutting fluid is recommended since this bit does not support coolant-through delivery. Inspect the cutting edge and coating for wear or chipping before each use, particularly when drilling hardened materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.90 mm (0.1142 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50.00 mm (1.9685 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 14.00 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 (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\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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: 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 Materials\u003c\/strong\u003e: Steel, Cast Iron, Hardened Materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.014 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: 0.025 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.35 inches length x 0.55 inches width x 0.45 inches height\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: 3330290\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727087305010,"sku":"3330290","price":110.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6610b5b7e64749449347a1ca53a6449c.jpg?v=1788673101","url":"https:\/\/voomisupply.com\/products\/osg-3330290-screw-machine-drill-bit-2-90mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
