With a 0.5709 inch (14.50 mm) cutting diameter and a 140-degree split point, this bit delivers accurate starts and consistent hole geometry without a center punch. The right-hand spiral flute geometry and R-thinned web reduce thrust and improve chip evacuation. Coolant-through capability makes it well suited for production machining environments where heat management is critical. Machinists, tool-room technicians, and CNC operators working in job shop or manufacturing settings are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for drilling steel, alloy steel, cast iron, titanium, and titanium alloys. The screw machine length body (shorter than jobber length) increases rigidity and reduces deflection in close-tolerance applications. Series 6500 construction with a tapered web and 3xD flute-to-diameter ratio supports deep hole stability in both manual and CNC setups. The straight-cylindrical shank with a 15.00 mm (0.5906 inch) shank diameter seats securely in standard drill chucks and collet holders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for superior hardness and wear resistance in ferrous and exotic alloys\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces thrust and improves self-centering on hard materials\u003c\/li\u003e\n  \u003cli\u003eR-thinned, tapered web lowers cutting force and extends tool life\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed production drilling with active chip and heat control\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body increases rigidity and minimizes runout versus jobber length\u003c\/li\u003e\n  \u003cli\u003eCoated finish for added surface hardness and lubricity during cutting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers, drill presses, and manual lathes accepting a straight-cylindrical shank.

Seat the straight-cylindrical shank fully in the chuck or collet holder and verify runout before cutting. Coolant-through connections should be confirmed leak-free before initiating a cutting cycle. Follow the machine manufacturer and tooling manufacturer feed-and-speed recommendations for the specific workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5709 inches (14.50 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, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 73.00 mm (2.874 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 140.00 mm (5.512 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 15.00 mm (0.5906 inches)\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\/Finish\u003c\/strong\u003e: Coated\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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, 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\u003eWeight\u003c\/strong\u003e: 0.59 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.85 inches L x 0.85 inches W x 0.75 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 8691450\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727412625714,"sku":"8691450","price":584.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b46ad03ea5170bff9de3e121ee42436_e4c94f64-3b14-429e-9b8c-49bbb106e6b9.jpg?v=1788677604","url":"https:\/\/voomisupply.com\/products\/osg-8691450-carbide-screw-machine-drill-bit-0-5709-in","provider":"Voomi Supply","version":"1.0","type":"link"}
