Built to Series 6500 specifications, it features a 0.2323 inch (5.90 mm) diameter, a 140-degree split point, and a two-flute spiral configuration with X-thinned web geometry. The EgiAs finish improves lubricity and wear resistance at the cutting edge. Coolant-through capability allows internal coolant delivery for deep-hole applications or high-speed runs in tough materials. Right-hand cut with a straight-cylindrical shank keeps setup straightforward on standard drill chucks and collet holders. Machinists and tool-and-die professionals specify this bit for accurate, repeatable hole entry with minimal thrust.\u003c\/p\u003e\u003cp\u003eThe 8690590 suits CNC machining centers, drill presses, and manual lathes in job shop, production floor, and toolroom settings. Its stub length format — overall length of 82.00 mm (approximately 3.23 inches) with a 30.00 mm (approximately 1.18 inch) flute length — provides added rigidity compared to jobber-length bits, reducing deflection when drilling close-tolerance holes in steel, stainless, cast iron, aluminum, and similar materials. It fits within the 0.2000 to 0.2500 inch diameter range of the Series 6500 family, making it a direct drop-in wherever that diameter is called out on a job card.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for hardness and thermal stability in high-speed drilling\u003c\/li\u003e\n\u003cli\u003eEgiAs finish reduces friction and extends tool life at the cutting edge\u003c\/li\u003e\n\u003cli\u003e140-degree point angle provides aggressive self-centering and clean entry\u003c\/li\u003e\n\u003cli\u003eX-thinned web lowers thrust requirements and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery for deep or high-volume drilling\u003c\/li\u003e\n\u003cli\u003eStub length format increases rigidity and minimizes deflection in close-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct substitute for screw machine length stub drill bits in the 0.2000 to 0.2500 inch diameter range; fits standard straight-cylindrical shank chucks and collet systems with a 6.00 mm (approximately 0.236 inch) shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed only with the machine powered down and locked out per applicable safety procedures. Secure the straight-cylindrical shank fully in the chuck or collet to the manufacturer-specified engagement depth before operation. Verify coolant-through passages are clear and compatible with the machine spindle before enabling internal coolant. Inspect the cutting edge for chips or wear before each use; carbide tooling is brittle and should not be forced or used in a damaged condition.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2323 inches (5.90 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 82.00 mm (approximately 3.23 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 30.00 mm (approximately 1.18 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (approximately 0.236 inches)\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\u003eWeb Thinning\u003c\/strong\u003e: X-Thinned\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: EgiAs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine Length)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Range\u003c\/strong\u003e: 0.2000 to 0.2500 inches (5.00 to 6.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.065 pounds\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: 8690590\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728828432690,"sku":"8690590","price":151.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b46ad03ea5170bff9de3e121ee42436_38fcedce-7a63-42b2-9c84-0c6f940fc1c9.jpg?v=1788696496","url":"https:\/\/voomisupply.com\/products\/osg-8690590-solid-carbide-stub-drill-bit-0-2323-in","provider":"Voomi Supply","version":"1.0","type":"link"}
