It features a standard 118-degree split-point geometry and a regular spiral flute configuration with web thinning for improved chip evacuation and reduced thrust when entering the cut. The straight cylindrical shank measures 0.1695 inches in diameter and 1.125 inches in length. Overall length is 3.25 inches with a 2.125-inch flute length, providing a 13xD depth-to-diameter ratio. This is a general-purpose drill intended for use by machinists, tool and die tradespeople, and maintenance technicians working in metal fabrication and industrial service environments.\u003c\/p\u003e\n\u003cp\u003eThe 5998219 is designed for drilling into steel, cast iron, non-ferrous metals, superalloys, and titanium. Its general-purpose grade and ANSI-standard geometry make it a standard stock item for drill presses, CNC machining centers, and hand-held power tools in both shop and field maintenance applications. The right-hand cut spiral flute suits conventional drilling setups without coolant-through capability. Typical uses include hole origination and through-hole drilling in sheet metal, structural components, and machined parts where wire-gauge sizing is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 18 at 0.1695 inches decimal diameter for precision hole sizing\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides hardness and heat resistance across a range of metal workpieces\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry force\u003c\/li\u003e\n  \u003cli\u003eRegular right-hand spiral flute promotes efficient chip removal during through-hole and blind-hole drilling\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish allows easy visual inspection for wear and re-sharpening\u003c\/li\u003e\n  \u003cli\u003eANSI-standard geometry ensures dimensional compatibility with standard drill chucks and holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber-length drill bit in the R10H-R18H series, suitable for standard 3-jaw drill chucks and collet systems accepting a 0.1695-inch straight cylindrical shank.

Secure the shank fully in the chuck and verify runout before beginning the cut. Always power down and de-energize the machine spindle before changing bits. Do not exceed the recommended maximum drilling depth of 2.125 inches for this bit size, and apply appropriate cutting fluid when drilling harder alloys to extend tool life.\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: 18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1695 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1695 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.125 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\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\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 13xD\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: 5998219\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51689328050482,"sku":"5998219","price":60.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4691d72f892b92915254364cb4aea851_c013260c-41f0-4f50-bc65-035f2e0c79a8.jpg?v=1788257646","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998219-jobber-drill-bit-18-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
