Built from powdered metal (PM) with a V coating, it delivers improved wear resistance and heat dissipation compared to standard HSS tooling. The bit features a 130-degree drill point angle with X-thinned web geometry for reduced thrust and easier self-centering. At 68 millimeters overall length with a 36-millimeter flute length, it fits standard drill chucks and CNC toolholders. The straight-cylindrical shank measures 4.00 millimeters in diameter. This is a right-hand cut, two-flute, spiral flute bit built for production and maintenance drilling environments.\u003c\/p\u003e\u003cp\u003eThe OSG 8612305 is rated for drilling into steel, alloy steel, cast iron, and nickel alloy workpieces. It is suited for blind hole drilling, cross hole drilling, through drilling, and self-centering applications. Wire size 31 corresponds to a decimal inch diameter of 0.1200 inches (3.05 millimeters), making it a common size for tapping pilot holes and precision bore work in metal fabrication, toolroom, and industrial maintenance settings. Machinists and tool-and-die professionals working with tight-tolerance hole requirements will find the X-thinned point and tapered web configuration particularly useful for minimizing walking and reducing breakout burrs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePowdered metal construction with V coating for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle optimized for steel, cast iron, and nickel alloys\u003c\/li\u003e\n\u003cli\u003eX-thinned web with tapered web configuration reduces cutting thrust and improves self-centering\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, two-flute spiral design with regular spiral type for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard Jacobs-style and collet-style holders\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of plus 0 to minus 0.018 millimeters for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance jobber length drill bit for use in drilling steel, alloy steel, cast iron, and nickel alloy workpieces.

Secure the shank fully in the chuck or collet and confirm runout before cutting. Power down and de-energize all machine spindles before changing tooling. Do not exceed the recommended feed and speed parameters for the workpiece material and machine type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 3.05 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 68.00 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 36.00 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 millimeters\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 (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: X-Thinned\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: Powdered Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Finish\/Coating\u003c\/strong\u003e: V Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0 to minus 0.018 millimeters\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\u003eSeries\u003c\/strong\u003e: 1950\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: 8612305\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51734774186290,"sku":"8612305","price":53.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dbee8a266b0fec63d4b30508ced3765d.jpg?v=1788766880","url":"https:\/\/voomisupply.com\/products\/osg-8612305-jobber-length-drill-bit-wire-31-pm","provider":"Voomi Supply","version":"1.0","type":"link"}
