It measures 3\/64 inch (0.0469 inch decimal) in diameter with an overall length of 1.75 inches and a flute length of 0.75 inches. The bit is manufactured from high speed steel with a bright, uncoated finish and features a standard 118-degree point angle. It belongs to the R10H-R18H series and is built to ANSI specifications. Licensed tradespeople and shop technicians working on drilling operations in light metalworking, HVAC fabrication, and related trades will find this a reliable production-grade tool.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling small-diameter holes in a wide range of workpiece materials including steel, cast iron, non-ferrous metals, and superalloys. The right-hand spiral flute design provides efficient chip evacuation during through-hole and blind-hole drilling. The straight cylindrical shank seats directly in standard drill chucks without adapters. Typical applications include sheet metal work, light structural fabrication, and precision hole placement where a 3\/64-inch diameter is required. The tapered web and web-thinned construction reduce thrust requirements at entry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/64 inch (0.0469 inch) diameter with matching straight-cylindrical shank diameter for true concentricity\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry into steel and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across repeated use without coating buildup concerns\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, 2-flute design with 16xD flute-to-diameter ratio promotes chip clearance in deeper passes\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces cutting resistance and prolongs point life\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant jobber-length geometry fits standard chuck sizes without modification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit in the PRECISION TWIST DRILL R10H-R18H series, compatible with any standard drill chuck accepting a straight-cylindrical shank of 0.0469 inch diameter. Rated for use in steel, cast iron, non-ferrous metals, and superalloys and titanium (workpiece material codes P, K, N, and S).\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a standard keyed or keyless drill chuck and tighten securely before operation to prevent shank slippage on small-diameter bits. Use appropriate cutting fluid or lubricant when drilling steel or superalloys to extend bit life and reduce heat buildup. Run at recommended surface footage for the workpiece material — excessive speed on hard alloys accelerates point wear on uncoated HSS bits. Inspect the point for chipping or wear before each use; regrind or replace if the 118-degree geometry is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Fractional)\u003c\/strong\u003e: 3\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal)\u003c\/strong\u003e: 0.0469 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0469 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\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\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 16xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10H-R18H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\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: 5998386\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51715193078066,"sku":"5998386","price":51.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac335c1d53632e99459aa82e5500dfd1_9e02554a-e8df-4f88-b18c-19f49d228793.jpg?v=1788510372","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998386-jobber-drill-bit-3-64-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
