It features a 118-degree standard point angle and a two-flute regular spiral design with web thinning for improved chip evacuation and reduced thrust at entry. The straight-cylindrical shank measures 0.3860 inches in diameter and 1.375 inches in length. Overall length is 5.125 inches with a flute length of 3.75 inches. This bit is designed for general-purpose drilling and is a standard choice for HVAC, mechanical, and industrial trade work where non-ferrous and general workpiece materials are encountered.\u003c\/p\u003e\n\u003cp\u003eThe 44393 is suited for general-purpose drilling in non-ferrous metals, plastics, and similar materials. The jobber-length profile balances reach and rigidity, making it practical for bench drilling, hand-held drill use, and drill press applications. Its DIN 338 compliance means it fits standard jobber-length tooling setups common in trade shops, fabrication environments, and field service work. The bright finish means no coating buildup concerns in sensitive alloy applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter W size: 0.3860 inches decimal equivalent\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web configuration\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for general-purpose durability\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for non-ferrous and general materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, two-flute regular spiral for consistent chip removal\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 standard for jobber-length drill bits\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 straight-shank drill chucks and keyed or keyless drill press and handheld driver setups that accept a 0.3860-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the shank fully in the chuck before operation and verify chuck key is removed before starting the drill. Use appropriate cutting fluid or lubricant when drilling metals to extend bit life and maintain hole tolerance. Follow applicable shop safety practices and OSHA guidelines for rotating cutting tools. Inspect the cutting edges for wear before each use and replace when point geometry is degraded.\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: W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3860 inches\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\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3860 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.375 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\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0010 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1164 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: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 44393\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51750607388978,"sku":"44393","price":16.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b9f7b6db69c577e5ef91ab60e5dd1072.jpg?v=1788917300","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-44393-drill-bit-letter-w-0-386-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
