It features a 0.166 inch (Wire Size 19) diameter, a 118-degree standard point angle, and a web-thinned, tapered-web construction that reduces thrust and improves chip evacuation. Made from high speed steel with a bright\/uncoated finish, this bit delivers consistent cutting performance in general-purpose and high-performance applications. The straight-cylindrical shank seats securely in standard drill chucks. It is sized to the ANSI standard and sold individually per package.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in screw machine operations and bench drilling applications where a short, rigid bit is required for accurate hole placement. The screw machine length format reduces deflection compared to jobber-length bits, making it a preferred choice when drilling in tight setups or when hole position tolerance is critical. The right-hand spiral flute with a 2.5xD flute-to-diameter ratio handles typical metal-cutting operations efficiently. Primary workpiece material rating includes titanium, indicating suitability for demanding alloy work as well as general ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire Size 19 diameter at 0.166 inches for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered-web design reduces entry thrust\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for high-performance applications including titanium\u003c\/li\u003e\n  \u003cli\u003eScrew machine length for increased rigidity and reduced deflection during drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with 2.5xD flute-to-diameter ratio for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant Series R41 design with bright\/uncoated finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct substitute for screw machine length drill bits in Wire Size 19 (0.1660 inches) within the 0.1500 to 0.2000 inch drill bit size range, conforming to ANSI standards for straight-shank screw machine drill bits.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists and trade professionals using standard drill chucks compatible with straight-cylindrical shanks. Secure the shank fully in the chuck before operation to prevent runout. Always wear appropriate eye protection and follow shop safety protocols when drilling. Ensure the workpiece is firmly clamped and the drill press or machine spindle speed is set appropriately for the workpiece material and bit diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1660 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 19\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 2.5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium\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: R41\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: High Performance\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: 0.042 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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5998817\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51695507538226,"sku":"5998817","price":43.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/367cc312ac68a5fb1414bbb1259b7168.jpg?v=1788335923","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998817-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
