It features a 3.90 mm diameter, a 140-degree R-thinned point for improved self-centering and reduced thrust, and an EgiAs coating that extends tool life in demanding applications. The 4.00 mm straight-cylindrical shank is compatible with standard drill chucks and collet systems. With an overall length of 86.00 mm and a flute length of 36.00 mm, this drill is suited for production environments where consistent hole quality and tool life are priorities. Installation and operation are performed by machinists and tooling technicians.\u003c\/p\u003e\n\u003cp\u003eThe OSG 8692390 is rated for use in steel, alloy steel, cast iron, titanium, and titanium alloys, covering ISO material codes P, K, S, and H. Typical applications include blind hole drilling, cross hole drilling, general drilling, and self-centering operations. The 5xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes. Coolant-through capability allows internal coolant delivery, making it effective in CNC machining centers and other coolant-equipped setups where heat and chip management are critical to hole quality.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eEgiAs coating for extended tool life and reduced friction in ferrous and exotic alloys\u003c\/li\u003e\n  \u003cli\u003e140-degree R-thinned point reduces thrust and improves self-centering without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal coolant delivery in equipped machines\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute geometry with tapered web for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 4.00 mm shank fits standard chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and drilling equipment capable of accepting a 4.00 mm straight-cylindrical shank.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing the drill. Verify shank seating depth and runout with the collet or chuck before beginning production cuts. Use appropriate cutting parameters for the workpiece material and confirm coolant supply is active when using the coolant-through feature.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.90 mm (0.1535 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\u003ePoint Type\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 86.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 36.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\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, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.018 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron, Titanium, Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Blind Hole, Cross Hole, Drilling, Self-Centering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6510\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: 0.031 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: 8692390\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731927892274,"sku":"8692390","price":181.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fc7f395c5a184e4c1cb69081dbd9d7aa.jpg?v=1788736735","url":"https:\/\/voomisupply.com\/products\/osg-8692390-carbide-jobber-drill-3-90mm-140-deg-egias","provider":"Voomi Supply","version":"1.0","type":"link"}
