It is manufactured from high-speed steel with a steam oxide coating that reduces friction and helps resist corrosion during drilling operations. The bit features a standard 118-degree split point and a two-flute spiral design with a tapered web configuration for efficient chip evacuation. With an overall length of 4.125 inches and a flute length of 2.875 inches, this bit handles general-purpose drilling in a wide range of materials. Licensed HVAC techs, plumbers, electricians, and mechanical contractors routinely use jobber-length bits like this for field drilling and fixture installation tasks.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. It is designed for general-purpose production and maintenance drilling in both shop and field environments. The straight-cylindrical shank fits standard three-jaw chucks on corded drills, cordless drills, and drill presses. The 10xD flute-to-diameter ratio keeps the bit rigid enough for accurate hole location across typical jobber-length applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter J size at 0.277 inches decimal diameter for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle suitable for general-purpose drilling across multiple material types\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating reduces friction and provides light corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eTwo-flute spiral design with tapered, web-thinned construction for efficient chip clearing\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with straight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for jobber-length drill geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style general-purpose jobber-length drill bit compatible with any standard three-jaw chuck accepting a 0.277-inch straight-cylindrical shank.

Ensure the workpiece is clamped or secured to prevent movement during drilling. Use appropriate cutting fluid or coolant when drilling stainless steel, cast iron, or hard alloys to extend bit life and maintain hole quality. Follow applicable ANSI and shop-safety guidelines when operating drilling equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.277 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\u003eOverall Length\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.277 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 inches\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10-R15-R18\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: 0.042 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: 5998814\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51707399602482,"sku":"5998814","price":15.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d1376067efa74e57cf29a3e46baef9d_4bed5a3c-7448-4870-83ee-09b28829cd67.jpg?v=1788440062","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998814-drill-bit-letter-j-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
