Built from solid carbide and finished with an EgiAs coating, this bit delivers the rigidity and wear resistance required for demanding production and maintenance drilling. It features a 180-degree web-thinned point for accurate self-centering on entry, reducing walking and the need for a center punch. With a 2-flute spiral configuration and a 3xD flute-to-diameter ratio, it efficiently evacuates chips while maintaining cutting stability. Overall length is 2.95 inches, keeping the short, stiff profile that screw machine drills are selected for.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling steel, alloy steel, and cast iron in both production shop and maintenance environments. The screw machine length format makes it a common choice for drill press work, CNC machining centers, and turret setups where tool overhang must be minimized. The straight cylindrical shank fits standard drill chucks and collet holders sized for 8 mm shanks. Coolant-through capability allows internal coolant delivery when the holder and machine support it, extending tool life in interrupted cuts or deep-feature drilling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eEgiAs coating applied to both the body and drill tip for improved surface lubricity\u003c\/li\u003e\n  \u003cli\u003e180-degree web-thinned point reduces thrust force and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design compatible with through-spindle coolant systems\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration maintains core strength along the flute length\u003c\/li\u003e\n  \u003cli\u003eSeries 5720 screw machine length format minimizes overhang and deflection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for machine setups requiring an 8 mm straight-shank screw machine length drill in solid carbide. Primary workpiece materials listed by the manufacturer are steel, alloy steel, and cast iron.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall into a drill chuck or collet holder rated for an 8 mm straight cylindrical shank, ensuring the shank is fully seated and the holder is properly torqued or tightened before operation. Machining professionals should verify spindle speed and feed rate against the material being drilled, as solid carbide tooling is sensitive to side loading and improper speeds. When using the coolant-through feature, confirm that coolant pressure and flow are within the machine tool manufacturer specifications before engaging. Inspect the drill point and flutes for chipping or wear before each use, particularly after cutting cast iron or hardened steel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8 mm (0.3150 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 75 mm (2.95 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm (0.3150 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Web-Thinned\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron\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: 0.1 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: 3334365\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752428372274,"sku":"3334365","price":255.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1009c2e4540f28444916b42e80c3ac5_2845f916-3457-48d5-b897-83de69e35128.jpg?v=1788928062","url":"https:\/\/voomisupply.com\/products\/osg-3334365-screw-machine-drill-bit-8mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
