It carries a 9\/32 inch (0.2811 inch decimal) diameter, a 140-degree R-thinned point for accurate self-centering entry, and an EgiAs coating that extends edge life in abrasive materials. The straight-cylindrical shank measures 5\/16 inch in diameter, and the overall length is 91 mm (approximately 3.58 inches). This bit is built for production environments where tool longevity and hole accuracy in tough materials are the primary concerns. Licensed machinists, tool-and-die shops, and metalworking fabricators are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill bit is well-suited for blind hole, cross hole, and through-hole drilling applications in steel, alloy steel, and cast iron. Its 5xD flute-by-diameter ratio and regular spiral flute geometry support efficient chip evacuation in these materials. The R-thinned web reduces thrust force at entry, making it practical for self-centering starts without a center punch in many setups. It is a Series 6310 tool from OSG, intended for use in CNC machining centers and manual drill presses with rigid setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance in ferrous and hard-alloy drilling\u003c\/li\u003e\n\u003cli\u003eEgiAs coating extends cutting-edge life in abrasive and high-strength workpiece materials\u003c\/li\u003e\n\u003cli\u003e140-degree R-thinned point promotes self-centering entry and reduces walking\u003c\/li\u003e\n\u003cli\u003eTapered web with R-thinning lowers axial thrust requirements\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with 53 mm flute length supports chip evacuation in deep cuts\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0 to -0.022 mm for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling steel, alloy steel, and cast iron workpieces. Suitable for blind hole, cross hole, general drilling, and self-centering applications. Fits any chuck or collet accepting a 5\/16-inch straight-cylindrical shank.

Secure the shank fully in a properly sized collet or drill chuck before operation, and verify runout before cutting. Always power down the spindle completely before changing bits. Follow applicable shop safety standards and machine manufacturer guidelines for carbide tooling speeds and feeds.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9\/32 inch (0.2811 inch \/ 7.15 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 91 mm (approximately 3.58 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53 mm\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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 Configuration\u003c\/strong\u003e: Tapered\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.022 mm\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\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: 0.1 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: 631028011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731764052274,"sku":"631028011","price":172.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/172810fc138da7ef9b15339ce5eada04_bb25a5b7-0522-4914-b164-1d4d7d181d53.jpg?v=1788734675","url":"https:\/\/voomisupply.com\/products\/osg-631028011-carbide-jobber-drill-bit-9-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
