It measures 0.5394 inches (13.70 mm) in diameter with a 140-degree split point and features two spiral flutes with R-thinned web geometry for improved chip evacuation and reduced thrust. The straight cylindrical shank measures 14.00 mm in diameter. At 134.00 mm overall length, the screw machine format provides added rigidity over jobber-length drills, making it well suited for CNC machining centers, drill presses, and manual lathes where shorter overhang reduces deflection. Coolant-through capability supports high-feed-rate operations in production environments.\u003c\/p\u003e\n\u003cp\u003eThe 8691370 is engineered for cutting steel, alloy steel, cast iron, titanium, and titanium alloys. Its coated solid carbide construction and 3xD flute-to-diameter ratio make it a practical choice for production shops running high-volume hole operations in ferrous and hard-to-machine materials. It is sized within the 0.5000 to 0.6000 inch decimal inch range, Series 6500, and is packaged as a single unit. Licensed machinists, tool and die makers, and CNC operators are the typical end users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces thrust and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eR-thinned, tapered web configuration minimizes cutting resistance\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed production drilling\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (3xD flute ratio) provides greater stability than jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eCoated finish for improved wear resistance and heat management\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct selection within the OSG Series 6500 product line for screw machine length carbide drill applications in the 0.5000 to 0.6000 inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists and CNC operators in machine shop environments. Secure the straight cylindrical shank firmly in a compatible drill chuck or collet before operation, and verify that spindle runout is within acceptable tolerances to avoid premature tool wear. Power down and de-energize all equipment before changing tooling. Coolant-through setups should have the coolant circuit confirmed and connected prior to running at production feed rates.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5394 inches (13.70 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\u003eFlute Length\u003c\/strong\u003e: 69.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 14.00 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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\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\u003eCoolant Through\u003c\/strong\u003e: Yes\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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron, Titanium, Titanium Alloy\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\u003eSeries\u003c\/strong\u003e: 6500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: 8691370\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51750698615090,"sku":"8691370","price":345.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b46ad03ea5170bff9de3e121ee42436_67d5241b-21b5-4ed6-bdc2-52e30cfc6002.jpg?v=1788918642","url":"https:\/\/voomisupply.com\/products\/osg-8691370-solid-carbide-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
