With a 0.5197-inch (13.20 mm) diameter, a 140-degree split point, and a coated finish, this bit delivers aggressive, accurate entry with reduced thrust. The straight-cylindrical shank seats securely in standard drill chucks and toolholders. The 2-flute spiral configuration with R-thinned, tapered web geometry promotes efficient chip evacuation and minimizes walking at the drill point. Coolant-through capability supports continuous high-speed operation in production machining environments. This bit is installed by machinist and toolroom professionals running CNC or manual drilling equipment.\u003c\/p\u003e\n\u003cp\u003eThe 8691320 is built for production and job-shop applications where material hardness and cycle time are primary concerns. Primary workpiece materials include steel, alloy steel, cast iron, titanium, and titanium alloys. The screw machine length body — shorter than a jobber bit — provides added rigidity and stability when drilling at high feed rates. With an overall length of 134.00 mm (approximately 5.28 inches) and a 3xD flute-to-diameter ratio, this bit suits shallow-to-moderate depth holes in tight setups. It fits machine tool spindles sized for a 14.00 mm (approximately 0.551-inch) shank diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle with R-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eCoated finish improves wear resistance and heat dissipation at cutting edges\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed, continuous-duty machining cycles\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body provides greater rigidity compared to jobber-length drills\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, 2-flute spiral with 3xD ratio for efficient chip clearing\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. Fits standard straight-cylindrical toolholders and drill chucks accepting a 14.00 mm shank. Part of OSG Series 6500 high-performance screw machine drill bits in the 0.5000 to 0.6000 inch (11.00 to 13.50 mm) size range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove this bit only with the machine spindle fully stopped and locked out per facility LOTO procedures. Ensure the straight-cylindrical shank is fully seated and the toolholder collet or chuck is torqued to the machine manufacturer specification before initiating a cycle. Verify coolant supply lines are clear and delivering adequate flow when using the through-coolant feature, as dry running at high speeds will shorten tool life. This bit is intended for use by qualified machinists familiar with carbide tooling handling — carbide is brittle and will chip or crack if dropped or cross-loaded.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5197 inches (13.20 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\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\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: 66.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 134.00 mm (approximately 5.28 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 14.00 mm (approximately 0.551 inches)\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\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 -0.027 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\u003eWeight\u003c\/strong\u003e: 0.49 pounds\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: 8691320\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737634832690,"sku":"8691320","price":339.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b46ad03ea5170bff9de3e121ee42436_4468e4e6-aaee-4799-817b-da7871702acf.jpg?v=1788791671","url":"https:\/\/voomisupply.com\/products\/osg-8691320-screw-machine-drill-bit-0-5197-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
