It features an XPM high-performance coating applied to a two-flute, right-hand spiral configuration with a 130-degree drill point angle optimized for aggressive entry and clean chip evacuation. The straight-cylindrical shank measures 6.00 millimeters in diameter, and the overall tool length is 66.00 millimeters, keeping the setup compact and rigid for stub-length applications. R-thinned web geometry reduces thrust load at the point and extends tool life in production environments. This bit is suited for machinists, tool-and-die workers, and metal fabricators running drill press, CNC, or manual lathe operations.\u003c\/p\u003e\u003cp\u003eThis screw machine drill bit is built for drilling steel, alloy steel, cast iron, and nickel alloys in both job-shop and production floor settings. The 3xD flute-to-diameter ratio and tapered web configuration make it well suited for short-hole drilling where rigidity and repeatability matter. The compact screw machine length reduces deflection compared to jobber-length alternatives, making it a practical choice for tight-tolerance work in fixture-mounted or turret setups. No coolant-through capability is required for typical applications within its intended workpiece material range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eXPM high-performance coating for extended tool life in ferrous and nickel alloy materials\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle for aggressive entry and reduced thrust on hard workpieces\u003c\/li\u003e\n\u003cli\u003eR-thinned web configuration reduces cutting force and improves point stability\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length provides maximum rigidity and minimal deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collets\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.

Secure the shank fully in a properly sized drill chuck or collet before operation, and confirm the workpiece is clamped or fixtured to prevent movement. Power down and de-energize all equipment before changing tooling. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection based on workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1660 inches (Wire Size 19 \/ 4.22 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 mm (approximately 2.60 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 22.00 mm (approximately 0.87 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (approximately 0.236 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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\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\u003eTool Material\u003c\/strong\u003e: XPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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 by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -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: 0.025 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: 8608422\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51738759692594,"sku":"8608422","price":78.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bb3bbc1959dc85e71fb4a12871360de2_847d3b7b-b26e-4516-9f3c-54fe76e2a111.jpg?v=1788804024","url":"https:\/\/voomisupply.com\/products\/osg-8608422-screw-machine-drill-bit-0-166-in-wire-19","provider":"Voomi Supply","version":"1.0","type":"link"}
