Built to Series 5720 specifications, it features a 180-degree web-thinned point for accurate entry and reduced thrust. The EgiAs coating improves wear resistance and heat dissipation, extending tool life in demanding production environments. At 1\/8 inch (3.17 mm) diameter with a 2.1654-inch overall length, this stub-length drill is suited for CNC machining centers, drill presses, and screw machine operations where rigidity and precision matter. Installation and operation are performed by machinists and tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eThis drill bit is engineered for cutting steel, alloy steel, and cast iron. The screw machine length format — shorter than jobber length — reduces deflection and improves hole location accuracy, making it a practical choice for tight-tolerance applications in production machining. The 3xD flute-to-diameter ratio and regular spiral flute geometry promote chip evacuation in short-depth holes. Coolant-through capability supports high-speed spindle operations where heat management is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e180-degree web-thinned point reduces entry thrust and improves centering accuracy\u003c\/li\u003e\n\u003cli\u003eEgiAs coating enhances wear resistance and tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed and high-feed machining operations\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length provides added rigidity and reduced deflection versus jobber-length bits\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eTapered web configuration with regular spiral flutes for consistent chip clearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling steel, alloy steel, and cast iron workpieces.

Ensure the spindle and workholding are fully stopped before changing tooling. Verify chuck or collet runout is within acceptable tolerances to avoid premature edge wear. When using coolant-through capability, confirm coolant lines are clear and pressure is appropriate for the spindle setup before starting the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 1\/8 inch (0.1250 inch \/ 3.17 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.1654 inches (55 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 15 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1250 inch\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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5720\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.3 inches L x 0.4 inches W x 0.55 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: 572012517\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731383583026,"sku":"572012517","price":123.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1009c2e4540f28444916b42e80c3ac5_9ee7439c-590d-4e4d-b3d4-bdf587966a26.jpg?v=1788730292","url":"https:\/\/voomisupply.com\/products\/osg-572012517-screw-machine-drill-bit-1-8-inch-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
