Built from high speed steel with a bright uncoated finish, it features a standard 118-degree split point and a two-flute regular spiral configuration. The straight cylindrical shank measures 0.0180 inches in diameter with a shank length of 11\/16 inches. Overall length is 7\/8 inches. This bit is a general-purpose drilling tool intended for use by machinists, toolroom technicians, and precision metalworking professionals who require small-diameter accuracy in production or maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for drilling steel, cast iron, non-ferrous metals, superalloys, and titanium. With a flute-to-diameter ratio of 10xD and a maximum drilling depth of 3\/16 inches, it suits shallow precision holes in both manual and CNC drilling applications. The web-thinned, tapered web design reduces thrust force when entering tough materials. It conforms to ANSI standards and carries a Series R10H-R18H designation. Typical use cases include fixture work, small fastener hole prep, and precision component fabrication in shop or field settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 77 with a decimal diameter of 0.0180 inches for precise small-hole work\u003c\/li\u003e\n  \u003cli\u003e118-degree standard drill point for general-purpose entry across multiple materials\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces thrust and improves penetration in harder workpieces\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, two-flute regular spiral for consistent chip evacuation in shallow drilling\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank for use in standard drill chucks without modification\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant construction to Series R10H-R18H specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production-use drill bit compatible with standard drill chucks and collets accepting a 0.0180-inch straight cylindrical shank.

Secure the shank fully in the chuck before operation to prevent runout. Do not exceed the recommended maximum drilling depth of 3\/16 inches per pass. When drilling superalloys or titanium, use appropriate cutting fluid to extend tool life and maintain hole quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 77\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0180 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit 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\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7\/8 inches (0.875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0180 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 11\/16 inches (0.6875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 10xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10H-R18H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 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: 5998354\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693319487794,"sku":"5998354","price":71.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4691d72f892b92915254364cb4aea851_16798c6a-ea98-410e-9649-fa5256a64129.jpg?v=1788310573","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998354-wire-77-hss-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
