It features a 140-degree point angle with R-thinned web geometry that improves self-centering and reduces thrust force at entry. The EgiAs coating extends tool life by resisting heat buildup and edge wear during sustained cutting operations. At 11.8 mm in diameter with a 118 mm overall length and 71 mm flute length, this bit fits standard CNC machining centers, drill presses, and manual machines where a straight-cylindrical shank is accepted. It is suited for production environments where tool consistency and hole quality are priorities.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for drilling steel, alloy steel, and cast iron in blind hole, cross hole, and self-centering applications. The 5xD flute-to-diameter ratio provides adequate chip clearance for moderate-depth holes without pecking cycles in many setups. Right-hand spiral flutes with a regular spiral type make it compatible with standard right-hand spindle equipment. The Series 6310 designation identifies it within the OSG high-performance carbide drill family. It is a single-piece, solid carbide construction with no brazed tip, which delivers consistent rigidity in demanding cutting conditions across job shop and production floor use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and consistent dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle with R-thinned web for improved self-centering and reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eEgiAs coating for extended tool life in steel and cast iron cutting\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 12 mm diameter for broad machine compatibility\u003c\/li\u003e\n  \u003cli\u003eSuitable for blind hole, cross hole, drilling, and self-centering applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe OSG 8673180 is designed for use in steel, alloy steel, and cast iron workpieces, and fits machines accepting a 12 mm straight-cylindrical shank. Primary workpiece material codes P, K, and H confirm suitability across these material groups. Coolant-through is not supported on this bit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists and tool-and-die technicians in CNC or manual drilling equipment. Confirm the collet or chuck is rated for a 12 mm straight shank and that the machine spindle is fully stopped before changing tooling. Diameter tolerance is +0 to -0.027 mm, so verify fit and runout with a dial indicator when hole precision is critical. Follow the machine manufacturer and OSG speed-and-feed recommendations for the specific workpiece material to avoid premature edge wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11.8 mm (0.4646 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 118 mm (approximately 4.65 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 71 mm (approximately 2.80 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint 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, Regular\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\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\u003eCoating\/Finish\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.027 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6310\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: 0.305 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: 8673180\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51735053435186,"sku":"8673180","price":378.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/172810fc138da7ef9b15339ce5eada04_9dd2b169-68dc-4b64-9350-0b0c08ee9e5f.jpg?v=1788769708","url":"https:\/\/voomisupply.com\/products\/osg-8673180-solid-carbide-jobber-drill-bit-11-8-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
