Built from XPM high-speed steel with a coated finish, this bit measures 0.1875 inches (3\/16 inch) in diameter with a 130-degree split point and a right-hand spiral flute. The shortened screw machine length provides increased rigidity compared to jobber-length bits, reducing deflection and improving hole accuracy in production drilling setups. It is part of OSG Series 1900 and carries a web-thinned, tapered web configuration for easier penetration at startup. Machinists, tool-and-die technicians, and production drilling operators are the primary users.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling steel, alloy steel, cast iron, and nickel alloy workpieces in CNC machining centers, drill presses, and manual production setups. The screw machine length format makes it a common choice for turret lathes, gang drills, and short-hole applications where rigidity matters more than reach. The 3xD flute-to-diameter ratio and tapered web support chip evacuation in interrupted cuts and through-hole applications across ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eXPM high-speed steel construction with coated finish for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle with R-thinned web for reduced thrust and cleaner entry\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length increases rigidity and reduces deflection versus jobber drills\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute geometry supports consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders without modification\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of plus 0 to minus 0.018 mm for close-tolerance hole applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard screw machine length drill bit in the OSG Series 1900 line, compatible with any drill chuck or collet system accepting a 6.00 mm straight-cylindrical shank.

Secure the shank fully in the chuck or collet and verify runout before drilling. Always power down and lock out the spindle before changing or inspecting tooling. Follow machine manufacturer guidelines for feed rate and spindle speed appropriate to the workpiece material and bit diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch, 4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 70.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 26.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\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: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0 to minus 0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1900\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.029 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: 8608476\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727405875506,"sku":"8608476","price":79.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3c0a69bf1f81f83686d5fb491c7ea0d.jpg?v=1788677488","url":"https:\/\/voomisupply.com\/products\/osg-8608476-screw-machine-drill-bit-3-16-in-xpm","provider":"Voomi Supply","version":"1.0","type":"link"}
