It measures 5\/16 inch (0.3125 inch decimal, 7.94 mm) in diameter with a 130-degree point angle and a V coating applied over a powdered metal substrate. The overall length is 119 mm with a 75 mm flute length, a straight-cylindrical shank, and a right-hand spiral flute configuration. The R-thinned point reduces thrust and improves self-centering on entry. Licensed machinists, tool-and-die techs, HVAC fabricators, and general metalworking shops routinely reach for this bit when production accuracy and tool life matter.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for drilling into steel, alloy steel, cast iron, and nickel alloy workpieces, covering ISO material codes P, K, S, and H. Typical applications include blind hole drilling, cross-hole drilling, standard through-hole drilling, and self-centering operations. The tapered web and regular spiral geometry make it well suited for both manual drill press setups and CNC drilling cycles where repeatable entry and chip evacuation are priorities. It does not support coolant-through delivery, so external coolant or cutting fluid applied at the point is the standard approach for harder materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16 inch diameter with tight tolerance of +0 to -0.022 mm for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle with R-thinned web for reduced thrust and improved self-centering\u003c\/li\u003e\n  \u003cli\u003eV coating over powdered metal construction for extended wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with tapered web promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders with 8.00 mm shank diameter\u003c\/li\u003e\n  \u003cli\u003eRated for steel, alloy steel, cast iron, and nickel alloy per ISO material codes P, K, S, and H\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in drill presses, CNC machining centers, and hand-held power drills accepting a straight-cylindrical shank.

Apply cutting fluid or external coolant at the drill point when working hardened steels or nickel alloys to manage heat buildup, since this bit does not support internal coolant delivery. Inspect the cutting edges and point coating for wear after extended runs, as a degraded V coating will increase thrust and reduce hole-diameter consistency. Follow shop lockout-tagout procedures before changing or inspecting the bit in any powered spindle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Inch)\u003c\/strong\u003e: 5\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.3125 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 7.94 mm\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\u003ePoint Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (mm)\u003c\/strong\u003e: 119.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length (mm)\u003c\/strong\u003e: 75.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003eMaterial\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron, Nickel Alloy\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1950\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.085 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 8612794\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728738287922,"sku":"8612794","price":100.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0dfcca2563dfb6b54d98f57a62b5b3d9.jpg?v=1788695645","url":"https:\/\/voomisupply.com\/products\/osg-8612794-jobber-drill-bit-5-16-inch-powdered-metal","provider":"Voomi Supply","version":"1.0","type":"link"}
