The 130-degree split point features R-thinned web geometry that reduces thrust and promotes self-centering without a pilot hole. Overall length is 4.45 inches (113 mm) with a flute length of 2.72 inches (69 mm). The straight-cylindrical shank measures 8 mm in diameter, fitting standard drill chucks. This bit is built for high-performance applications in ferrous and hard-material drilling environments and is installed by machinists, maintenance technicians, and tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eThe OSG 8612690 is suited for blind hole drilling, cross-hole drilling, through-hole drilling, and self-centering operations. Primary workpiece materials include steel, alloy steel, cast iron, and nickel alloys, covering a broad range of industrial and maintenance machining tasks. The tapered web configuration and regular spiral geometry support consistent chip evacuation in these materials. This bit does not support coolant-through delivery and is intended for use in conventional drilling setups with flood coolant or cutting fluid applied externally.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter I size: 0.2717 inches (6.91 mm) diameter with a tolerance of +0 to -0.022 mm\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle with R-thinned web for reduced thrust and self-centering entry\u003c\/li\u003e\n\u003cli\u003ePowdered metal construction with V coating for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral design promotes chip evacuation in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 8 mm diameter for standard chuck compatibility\u003c\/li\u003e\n\u003cli\u003eRated for blind hole, cross-hole, through-hole, and self-centering drilling operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling steel, alloy steel, cast iron, and nickel alloy workpieces.

Confirm spindle speed and feed rate are appropriate for the workpiece material and bit diameter before starting the cut. Apply cutting fluid or flood coolant externally during drilling to manage heat, as this bit does not support coolant-through delivery. Inspect the cutting edges and web area for wear or chipping before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2717 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 6.91 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.45 inches (113 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.72 inches (69 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: V Coated\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 Materials\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: 0.07 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: 8612690\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728830824754,"sku":"8612690","price":81.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3cd5644ff0302b4876d5b940b1ac4c36_62f7789d-2cf0-45ea-a9a9-cd8cea3445d8.jpg?v=1788696534","url":"https:\/\/voomisupply.com\/products\/osg-8612690-jobber-drill-bit-letter-i-130-degree-pm","provider":"Voomi Supply","version":"1.0","type":"link"}
