Manufactured from high speed steel with a bright uncoated finish, it features a standard 118-degree drill point angle and a two-flute spiral configuration with a regular spiral type. The overall length is 1.625 inches, and the flute length is 0.6875 inches, yielding a flute-to-diameter ratio of 17xD. The shank is straight-cylindrical at 0.0400 inches diameter. This is a general-purpose bit intended for bench drilling, drill presses, and hand-held power drills used by machinists, maintenance technicians, and metalworking tradespeople.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling steel, cast iron, non-ferrous metals, superalloys, and titanium in light production and maintenance applications. The web-thinned, tapered-web construction reduces thrust at entry and improves chip clearance, making it well-suited for small-diameter work where control and precision matter. Right-hand cutting action is standard. The bit is part of the R10H-R18H series and conforms to ANSI standards, making it appropriate for general shop use where consistent tolerances are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge 60 diameter — 0.0400 inches decimal equivalent\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered-web geometry for reduced thrust\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides durability across steel, cast iron, non-ferrous metals, and superalloys\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — compatible with a wide range of cutting fluids\u003c\/li\u003e\n\u003cli\u003eRegular spiral, two-flute design promotes efficient chip evacuation in small-diameter holes\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI specification designation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in standard drill chucks accommodating 0.0400-inch straight-cylindrical shanks.

Secure the shank fully in the drill chuck before operation and verify chuck runout to avoid bit deflection or breakage at this diameter. Power down or de-energize the drilling equipment fully before changing bits. Coolant-through is not supported; apply cutting fluid externally as appropriate for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0400 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\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\u003eFlute Length\u003c\/strong\u003e: 0.6875 inches (11\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.6875 inches (11\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.625 inches (1-5\/8 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: 0.0400 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.9375 inches (15\/16 inches)\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: 17xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10H-R18H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Drilling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 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: PRECISION TWIST DRILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5998066\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51699891732786,"sku":"5998066","price":49.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4691d72f892b92915254364cb4aea851_0c63ebd6-06bb-4e05-8eda-ffa755c44f40.jpg?v=1788382675","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998066-drill-bit-wire-60-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
