Built from solid carbide, it delivers the rigidity and wear resistance needed when cutting through steel, alloy steel, cast iron, titanium, and titanium alloys. The bit features a 140-degree drill point angle with R-thinned web geometry, which reduces thrust and improves centering at entry. Two spiral flutes evacuate chips efficiently, and the straight-cylindrical shank provides secure, concentric seating in standard drill chucks and collets. Coolant-through capability supports high-speed production environments where heat management is critical. This bit is sold individually.\u003c\/p\u003e\u003cp\u003eThe 650043711 is suited for machine shop and production environments where short, rigid drill geometry is preferred over jobber-length bits. The screw machine length profile minimizes deflection and runout in CNC machining centers, turret lathes, and drill presses. Its 3xD flute-to-diameter ratio makes it a practical choice for shallow-to-moderate depth holes in ferrous and hard-metal workpieces. Shops working with tight-tolerance bores in steel components and titanium aerospace parts will find this bit a reliable production tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for high rigidity and extended tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e140-degree split-point geometry with R-thinned web reduces entry thrust and improves self-centering\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed cutting and heat dissipation at the cutting zone\u003c\/li\u003e\n\u003cli\u003e2-flute spiral configuration provides efficient chip evacuation in ferrous materials\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard chucks and collets without adapters\u003c\/li\u003e\n\u003cli\u003eScrew machine length body minimizes deflection and improves hole-position accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers, turret lathes, and drill presses where a 7\/16 inch straight-shank screw machine length carbide drill bit is required. Primary workpiece materials include steel, alloy steel, cast iron, titanium, and titanium alloy.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit should be installed by a qualified machinist or toolroom technician familiar with carbide tooling. Ensure the spindle and chuck or collet are clean and free of runout before seating the shank. Carbide is brittle — avoid side loading, interrupted cuts without proper feed-rate adjustment, and impact conditions that would be acceptable with high-speed steel tooling. Always verify coolant flow is active before engaging the cut when using the through-coolant feature.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 7\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.4374 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 11.11 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 56.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 120.00 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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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: Coated\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.027 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron, Titanium, Titanium Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.29 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 650043711\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737646694706,"sku":"650043711","price":422.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c93da39f6bff9651dec17b6f1c58b900.jpg?v=1788791829","url":"https:\/\/voomisupply.com\/products\/osg-650043711-screw-machine-drill-bit-7-16-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
