It measures 0.80 mm (0.0315 inches) in diameter with an overall length of 38.00 mm (approximately 1.50 inches) and a shank diameter of 3.00 mm (approximately 0.118 inches). The bit is manufactured from XPM high-speed steel and features an XPM coating for extended tool life under demanding cutting conditions. A 130-degree split point angle reduces walking and improves entry accuracy. The X-Thinned web configuration lowers thrust requirements, making it well suited for precision drilling on manual machines, CNC equipment, and screw machine setups. Licensed machinists and tool-and-die technicians are the primary installers of this bit.\u003c\/p\u003e\u003cp\u003eThe OSG 8599008 is intended for drilling into steel, alloy steel, cast iron, and nickel alloys. Its screw machine length profile -- shorter than a jobber bit -- provides added rigidity and reduced deflection in short-reach applications. The 3xD flute-to-diameter ratio and spiral flute geometry promote efficient chip evacuation during through-hole and blind-hole operations. This bit is well matched to production environments where dimensional accuracy and tool life consistency are critical, including machining shops, maintenance facilities, and precision fabrication operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eXPM high-speed steel construction with XPM coating for extended wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle with X-Thinned web reduces thrust and improves hole entry precision\u003c\/li\u003e\n\u003cli\u003eScrew machine length (38.00 mm overall) provides rigidity and minimizes deflection in tight setups\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders without modification\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute geometry promotes consistent chip evacuation from the cutting zone\u003c\/li\u003e\n\u003cli\u003eCoolant-through feature is not present; suited for conventional flood or dry cutting methods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance screw machine length drill bit for use in steel, alloy steel, cast iron, and nickel alloy workpieces across the 0.0000 to 0.1000 inch decimal inch size range, OSG Series 1900.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine powered down and the spindle fully stopped. The straight-cylindrical shank should be secured in a properly sized collet or drill chuck to the full engagement depth to prevent slippage under cutting loads. Always verify spindle speed and feed rate are appropriate for the workpiece material and bit diameter before starting the cut. Handle small-diameter bits with care to avoid bending or chipping the flutes during setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0315 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 0.80 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 38.00 mm (approximately 1.50 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.00 mm (approximately 0.197 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm (approximately 0.118 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: XPM High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: XPM Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, X-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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 -0.014 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1900\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: 0.01 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: 8599008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732492615986,"sku":"8599008","price":49.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2af88842d2c8aaf7cac0c747d5b43a4c.jpg?v=1788743539","url":"https:\/\/voomisupply.com\/products\/osg-8599008-screw-machine-drill-bit-0-0315-in-xpm","provider":"Voomi Supply","version":"1.0","type":"link"}
