Built to Series 6550 specifications, it features a 1\/8 inch (0.1250 inch decimal) cutting diameter with a 140-degree split point and an EgiAs coating for extended tool life and heat resistance. The bit includes coolant-through capability, making it well suited for deep-hole drilling where chip evacuation and thermal management are critical. At a 25xD flute-to-diameter ratio, it delivers exceptional reach in tight or deep-bore scenarios. This tool is intended for use by machinists and tooling professionals working with CNC machining centers, drill presses, and precision boring equipment.\u003c\/p\u003e\n\u003cp\u003eThe OSG 655012512 is used in production and precision machining environments where extended reach and tight tolerances are required. The straight-cylindrical shank allows direct chucking in standard collets and drill chucks without adapters. Its right-hand cutting direction and two-flute geometry make it appropriate for drilling into ferrous and non-ferrous metals, hardened alloys, and other materials where solid carbide tooling is specified. The X-Thinned web reduces thrust force at the cutting point, improving penetration efficiency in harder workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding materials\u003c\/li\u003e\n  \u003cli\u003eEgiAs coating provides thermal protection and reduced friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation in deep-hole drilling applications\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle with X-Thinned web reduces entry thrust and walking\u003c\/li\u003e\n  \u003cli\u003e25xD flute-to-diameter ratio delivers extended reach beyond standard jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard collets and drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification solid carbide extra length drill bit for use in CNC machining centers and precision drilling equipment requiring a 1\/8 inch straight-cylindrical shank tool.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the machine in a fully stopped and locked-out state per applicable safety procedures. Ensure the collet or chuck is clean and undamaged before seating the shank to full engagement depth. Do not exceed the spindle speed and feed rate parameters specified for solid carbide tooling in the workpiece material being drilled. Coolant-through connections should be verified before initiating deep-hole drilling cycles.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 165.00 mm (approximately 6.50 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 95.00 mm (approximately 3.74 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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 by Diameter Ratio\u003c\/strong\u003e: 25xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: X-Thinned\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\u003eSeries\u003c\/strong\u003e: 6550\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: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241637\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: 655012512\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51729133732146,"sku":"655012512","price":589.15,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b545a6fc38d2088df443cd3a3fa9f2d.jpg?v=1788700605","url":"https:\/\/voomisupply.com\/products\/osg-655012512-extra-length-drill-bit-1-8-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
