Built from solid carbide and finished with an EgiAs coating, it delivers durability and wear resistance in demanding production and toolroom environments. The bit features a 3\/8 inch (9.53 mm) diameter, a 180-degree web-thinned point for accurate self-centering entry, a 2-flute regular spiral configuration, and coolant-through capability for improved chip evacuation and tool life. Overall length is 3.35 inches (85 mm), making it well suited for close-quarters and screw machine applications. Installation is performed by machinists and toolroom technicians.\u003c\/p\u003e\u003cp\u003eThis drill bit fits screw machine and CNC turning center applications where stub-length tooling is required. Its 3xD flute-to-diameter ratio suits shallow to moderate-depth holes in ferrous workpiece materials including steel, alloy steel, and cast iron. The straight-cylindrical shank accommodates standard drill chucks and collet holders sized for 3\/8 inch shanks. The EgiAs coating is optimized for dry or minimum-quantity-lubrication cutting conditions, though the coolant-through design also supports flood or through-spindle coolant delivery. This bit is part of OSG Series 5720 and is intended for production-volume drilling operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eEgiAs coating applied to both body and drill tip for enhanced wear resistance\u003c\/li\u003e\n\u003cli\u003e180-degree web-thinned point improves centering and reduces entry thrust force\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports flood coolant or through-spindle delivery for chip control\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard chucks and collet holders at 3\/8 inch diameter\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length at 3.35 inches overall for rigid, close-clearance setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and production tooling option for screw machine and CNC lathe operations requiring a 3\/8 inch solid carbide drill in the OSG Series 5720 family.

Disengage machine power and ensure the spindle has come to a complete stop before changing tooling. Verify chuck or collet bore is clean and sized correctly for the 0.3750 inch shank before tightening. Follow machine manufacturer torque and runout specifications for tool holding; excessive runout will reduce tool life and hole accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/8 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.35 inches (85 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 42 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 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: 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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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 -0.022 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: 0.16 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: 572037517\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51744554221874,"sku":"572037517","price":323.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1009c2e4540f28444916b42e80c3ac5_6a8eb2af-e161-4fe7-898c-52962ae29d51.jpg?v=1788858058","url":"https:\/\/voomisupply.com\/products\/osg-572037517-screw-machine-drill-bit-3-8-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
