It measures 4.90 mm in diameter with an overall length of 95.00 mm and a flute length of 45.00 mm. The 140-degree split point geometry reduces thrust and improves centering without a center punch. The EgiAs coating provides enhanced lubricity and heat resistance, extending tool life in ferrous and non-ferrous materials. Two spiral flutes with X-thinned web geometry promote efficient chip evacuation. Coolant-through capability supports high-speed drilling cycles in production environments. This bit is installed by machinists and CNC operators on vertical machining centers, drill presses, and multi-axis turning centers.\u003c\/p\u003e\u003cp\u003eThe OSG 8692490 is suited for production drilling in general metalworking, aerospace component fabrication, die and mold work, and precision machining shops. The straight-cylindrical shank with a 5.00 mm diameter fits standard drill chucks and collet systems. The right-hand cutting direction and spiral flute design make it compatible with conventional CNC spindle rotation. Its 5xD flute-to-diameter ratio places it in the standard jobber category, appropriate for through-hole and blind-hole applications within its size range of 4.00 mm to 5.00 mm.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eEgiAs coating for improved heat resistance and reduced built-up edge\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with X-thinned web for reduced thrust and self-centering entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-feed, high-speed drilling cycles\u003c\/li\u003e\n\u003cli\u003eTwo spiral flutes promote consistent chip evacuation in both through and blind holes\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-length drill for use in CNC machining centers, drill presses, and multi-spindle setups accepting a 5.00 mm straight-cylindrical shank within the 4.00 mm to 5.00 mm drill size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by qualified machinists with the machine powered down and spindle fully stopped. Ensure the chuck or collet is clean and undamaged before seating the shank to the full grip depth. Confirm spindle rotation is set to right-hand before initiating a cut. When using coolant-through capability, verify coolant pressure and flow are within the machine tool and toolholder specifications before running.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.90 mm (0.1929 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 95.00 mm (3.74 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 45.00 mm (1.77 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5.00 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: X-Thinned\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\u003eCoating\u003c\/strong\u003e: EgiAs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.85 inches (L) x 0.45 inches (W) x 0.35 inches (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 8692490\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728850649394,"sku":"8692490","price":159.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36adc2d2617bb4917925c3f830045324_64bc9257-d7ff-4c28-aad9-1344027ffefb.jpg?v=1788696819","url":"https:\/\/voomisupply.com\/products\/osg-8692490-solid-carbide-jobber-drill-4-90-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
