Built from solid carbide with an EgiAs multi-layer finish, it delivers extended tool life and thermal resistance compared to HSS alternatives. The 140-degree split point with R-thinning reduces entry thrust and promotes self-centering without a center punch. At 11.30 mm (0.4449 inches) in diameter with a 118.00 mm overall length, this bit is designed for machinists, tool-and-die professionals, and CNC operators working production or precision drilling applications.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for blind hole drilling, cross hole drilling, through-hole drilling, and self-centering applications. It performs in steel, alloy steel, and cast iron. The 5xD flute-to-diameter ratio supports adequate chip evacuation in moderate-depth holes without through-coolant. It is a solid choice for manual drill press, VMC, or HMC setups where rigidity and dimensional accuracy matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for use in steel, alloy steel, and cast iron\u003c\/li\u003e\n\u003cli\u003e140-degree R-thinned split point for self-centering and reduced thrust at entry\u003c\/li\u003e\n\u003cli\u003eEgiAs multi-layer finish for heat resistance and extended cutting edge life\u003c\/li\u003e\n\u003cli\u003eRegular right-hand spiral flute with tapered web for chip control\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 12.00 mm for standard collet or chuck mounting\u003c\/li\u003e\n\u003cli\u003e5xD flute length ratio supports blind hole and cross hole applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specification OSG Series 6310 jobber-length drill bit for machining steel, alloy steel, and cast iron workpieces.

Secure the straight-cylindrical shank fully within the collet or chuck to the recommended engagement depth before operation. Carbide is brittle — avoid side loading, interrupted cuts without proper feed rate adjustment, and thermal shock from intermittent coolant application. Confirm spindle runout is within acceptable tolerance before use to prevent premature edge chipping.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11.30 mm (0.4449 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 118.00 mm (4.65 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 71.00 mm (2.80 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12.00 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\u003ePoint Type\u003c\/strong\u003e: R-Thinned Split Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: 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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: EgiAs Multi-Layer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron\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: 6310\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.295 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: 8673130\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731683246386,"sku":"8673130","price":343.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/172810fc138da7ef9b15339ce5eada04_fed9f103-bc3f-49fa-bd6c-3ed874a83156.jpg?v=1788733861","url":"https:\/\/voomisupply.com\/products\/osg-8673130-jobber-length-drill-bit-11-30mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
