With a 0.1339-inch (3.40 mm) diameter and a 140-degree split point, this bit delivers fast, accurate hole starting without a center punch. The EgiAs coating provides enhanced lubricity and heat resistance for extended tool life in demanding cutting conditions. Two spiral flutes evacuate chips efficiently, and the X-thinned web reduces thrust requirements. Internal coolant-through capability supports high-speed production drilling. This bit is intended for use by machinists and tool-and-die professionals in CNC and manual drill press environments.\u003c\/p\u003e\u003cp\u003eThe OSG 8690340 is suited for screw machine operations, CNC machining centers, and drill press applications where stub-length rigidity is required. The straight-cylindrical shank fits standard drill chucks and collet holders. Its compact stub-length geometry minimizes deflection, making it a strong choice for tight-tolerance hole work in steel, stainless, and other ferrous materials. The coolant-through design makes it compatible with high-pressure coolant systems common in production shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for superior hardness and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle for self-centering starts and reduced walking\u003c\/li\u003e\n\u003cli\u003eEgiAs coating for improved lubricity and extended tool life under heat\u003c\/li\u003e\n\u003cli\u003eX-thinned web reduces axial thrust and improves chip clearing\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-pressure internal coolant delivery\u003c\/li\u003e\n\u003cli\u003eStub-length body maximizes rigidity and minimizes deflection in precision drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement or production drill bit within OSG Series 6500, sized for applications requiring a 0.1339-inch (3.40 mm) diameter hole in the decimal inch range of 0.1000 to 0.1500 inches.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with CNC or manual drilling equipment. Ensure the spindle and coolant system are fully powered down before loading or changing tooling. Secure the straight-cylindrical shank fully in a compatible drill chuck or collet to the appropriate engagement depth before operation. Always verify spindle speed and feed rate are appropriate for the workpiece material and diameter before cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1339 inches (3.40 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: EgiAs\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\u003eFlute Length\u003c\/strong\u003e: 21.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 74.00 mm (approximately 2.91 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: 4.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: X-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.05 x 0.45 x 0.40 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 8690340\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51753586196786,"sku":"8690340","price":152.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b46ad03ea5170bff9de3e121ee42436_0ed7e74d-7a0d-4767-baa4-249ffb45880b.jpg?v=1788938420","url":"https:\/\/voomisupply.com\/products\/osg-8690340-carbide-stub-drill-bit-0-1339in-140deg","provider":"Voomi Supply","version":"1.0","type":"link"}
