Built from high-speed steel (HSS) with a bright, uncoated finish, it features a 118-degree standard point angle and a left-hand cutting direction. The straight shank measures 1\/4 inch in diameter, and the overall length is 4 inches with a flute length of 2.75 inches. The web-thinned, tapered web construction reduces thrust requirements at entry. This bit is suitable for use by machinists, pipefitters, electricians, and general trade professionals working with metal substrates.\u003c\/p\u003e\n\u003cp\u003eThis Series L10 jobber-length bit is sized at 1\/4 inch (0.2500 inch decimal, Letter E equivalent) and is intended for drilling operations in residential and commercial trade applications. The left-hand cutting direction makes it particularly useful for removing broken fasteners or for use with left-hand-threaded components. It is rated for drilling in steel and cast iron workpieces and carries an ANSI specification designation. Maximum drilling depth matches the flute length at 2.75 inches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand cutting direction — effective for broken bolt extraction and reverse-threaded applications\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eHSS construction with bright, uncoated finish for general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute, 2-flute configuration with an 11xD flute-to-diameter ratio\u003c\/li\u003e\n  \u003cli\u003eStraight shank at 0.2500 inch diameter for use in standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant Series L10 jobber-length geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with standard drill chucks accepting a 1\/4-inch straight shank.

Left-hand bits require a reversible drill set to left-hand (counterclockwise) rotation. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat buildup. Always wear appropriate eye protection and secure the workpiece to prevent movement during drilling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 1\/4 inch (0.2500 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: E\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: HSS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches (101.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.75 inches (69.85 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\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: Regular Spiral\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: L10\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: 0.47 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: 5995463\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51697680023858,"sku":"5995463","price":24.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/700097b531762e7d1f9969c9cacad3be_8373f196-cac7-4a0f-bb1d-ad5d3f2bb341.jpg?v=1788354063","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5995463-1-4-in-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
