It measures 0.3228 inches (8.20 mm) in diameter with a 140-degree split point and features a coated finish for extended tool life. The two-flute spiral design with R-thinned web geometry reduces entry force and improves chip evacuation. At 101.00 mm overall length with a 41.00 mm flute length, this stub-length bit delivers rigidity and accuracy in CNC machining centers, drill presses, and screw machine setups. Coolant-through capability supports high-speed production runs in tough materials. Weighing 0.155 pounds, it ships individually.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for machinists, tool-and-die techs, and production shop operators working with steel, alloy steel, cast iron, titanium, and titanium alloys. The screw machine length format is standard in applications requiring a short, rigid tool for close-tolerance hole making, particularly on CNC lathes, turret-style screw machines, and machining centers where spindle-to-workpiece clearance is limited. The straight-cylindrical shank accepts standard drill chucks and collet holders with a 9.00 mm shank diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and heat resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle reduces thrust and improves self-centering on flat and curved surfaces\u003c\/li\u003e\n  \u003cli\u003eCoated finish extends tool life and reduces built-up edge in ferrous and titanium workpieces\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed drilling with internal coolant delivery\u003c\/li\u003e\n  \u003cli\u003eR-thinned tapered web lowers cutting resistance and improves chip flow\u003c\/li\u003e\n  \u003cli\u003e3xD flute-to-diameter ratio provides a compact, vibration-resistant cutting profile\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, alloy steel, cast iron, titanium, and titanium alloy workpieces.

Ensure the machine spindle is fully stopped and locked out before changing or chucking the bit. Verify shank seating and runout with a dial indicator before production drilling. Follow machine tool manufacturer guidelines for spindle speed, feed rate, and coolant pressure when using coolant-through tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3228 inches (8.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 101.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 41.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9.00 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\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\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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\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, 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: 0.155 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.15 inches length x 0.65 inches width x 0.55 inches height\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: 8690820\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752992309554,"sku":"8690820","price":294.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b46ad03ea5170bff9de3e121ee42436_58c62ad7-ed5e-4198-b249-e48392c69571.jpg?v=1788931931","url":"https:\/\/voomisupply.com\/products\/osg-8690820-carbide-screw-machine-drill-bit-0-3228-in","provider":"Voomi Supply","version":"1.0","type":"link"}
