The point is ground to 130 degrees with an R-thinned web, which reduces thrust force and aids self-centering when entering the workpiece. The spiral flute geometry is a regular helix with a tapered web configuration, and the cutting direction is right hand. With an overall length of 113 mm and a flute length of 69 mm, this is a standard jobber-length tool suited to drill presses, CNC machining centers, and handheld power tools used in metalworking trades.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for drilling steel, alloy steel, cast iron, and nickel alloy workpieces, placing it in material groups P, K, S, and H. Typical applications include blind hole drilling, cross hole operations, general through-hole drilling, and self-centering entry cuts. The straight-cylindrical shank with an 8.00 mm diameter seats in standard drill chucks and collets without modification. It is classified as a high-performance grade tool, making it appropriate for production environments where cycle time and tool life matter, not just occasional use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter L size: 0.2900 inch (7.37 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 entry thrust and improved self-centering\u003c\/li\u003e\n  \u003cli\u003ePowdered metal construction with V coating for extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with tapered web — 2 flutes, 69 mm flute length\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 8.00 mm diameter fits standard chucks and collets\u003c\/li\u003e\n  \u003cli\u003eRated for blind hole, cross hole, through-hole drilling, and self-centering applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, alloy steel, cast iron, and nickel alloy workpieces.

Use appropriate cutting fluid or coolant when drilling nickel alloys and hardened steels to manage heat buildup, as this bit does not have through-coolant capability. Inspect the cutting edge and web thinning for wear or chipping before each use; a worn R-thinned point will wander on entry and produce oversized holes. Follow the machine manufacturer and applicable shop safety guidelines for spindle speed and feed rate selection based on workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2900 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 7.37 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\u003eOverall Length\u003c\/strong\u003e: 113 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 69 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\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 (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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron, Nickel Alloy\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: +0 to -0.022 mm\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\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: 8612737\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730499109170,"sku":"8612737","price":100.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3cd5644ff0302b4876d5b940b1ac4c36_cc6308c7-e508-43d6-8874-91cae7db7c54.jpg?v=1788718542","url":"https:\/\/voomisupply.com\/products\/osg-8612737-jobber-length-drill-bit-letter-l-130-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
