It features a 140-degree point angle with R-thinned web geometry, a spiral regular-helix flute, and an EgiAs coating for extended tool life in demanding applications. The straight-cylindrical shank measures 6.00 mm in diameter, and the overall length is 82.00 mm with a 44.00 mm flute length. Rated as high-performance tooling, this bit is designed for machinists, tool-and-die workers, and CNC operators working in production environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling blind holes, cross holes, and self-centering operations in steel, alloy steel, and cast iron. The 5xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes without coolant-through capability. It is appropriate for manual drill presses, CNC machining centers, and gang drilling setups in job shops or production facilities. The EgiAs coating and solid carbide substrate make it a reliable choice for high-cycle applications where HSS bits wear prematurely.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003eEgiAs coating extends cutting life in steel, alloy steel, and cast iron\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with R-thinned web for improved self-centering and reduced thrust\u003c\/li\u003e\n\u003cli\u003eSpiral regular-helix flute design with tapered web configuration for chip clearance\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eRated for blind hole, cross hole, drilling, and self-centering tool applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in applications requiring a No. 12 wire gauge (0.1890 inch \/ 4.80 mm) drill diameter. Primary workpiece materials are steel, alloy steel, and cast iron (material codes P, K, and H). Compatible with standard straight-shank drill chucks and ER collet systems accepting a 6.00 mm shank. Part of the OSG Series 6310 high-performance carbide drill family.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit should be installed and removed by a qualified machinist following standard toolroom safety procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Use a calibrated chuck or collet holder sized for a 6.00 mm straight shank to ensure concentricity and prevent runout. Do not exceed the recommended feed and speed parameters for the workpiece material, as solid carbide is brittle and sensitive to lateral loading.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1890 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 4.80 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit 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\u003ePoint 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 44.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 82.00 mm (approximately 3.23 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: 6.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Applications\u003c\/strong\u003e: Blind Hole, Cross Hole, Drilling, Self-Centering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6310\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.25 inches L x 0.45 inches W x 0.35 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.051 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: 8672480\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736331452722,"sku":"8672480","price":105.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/172810fc138da7ef9b15339ce5eada04_43528452-670d-400a-8b8f-855f3a3fc8ea.jpg?v=1788777273","url":"https:\/\/voomisupply.com\/products\/osg-8672480-solid-carbide-jobber-drill-bit-no-12","provider":"Voomi Supply","version":"1.0","type":"link"}
