Built from high speed steel (HSS) with a bright, uncoated finish, it carries a 118-degree radial point and a regular spiral flute for reliable chip evacuation. The 4.00 mm diameter measures 0.1575 decimal inches, with an overall length of 75.00 mm (2.9528 inches) and a flute length of 43.00 mm (1.6929 inches). Web-thinned construction reduces point entry resistance. This bit is installed by machinists, maintenance mechanics, and trade professionals working with drill presses, lathes, and hand-held power drills.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for use in aluminum, non-ferrous metals, and similar softer workpiece materials in general-purpose applications. It follows DIN 338 specification, which governs jobber-length drills used widely in production and field service settings. The straight cylindrical shank seats in standard chucks accepting a 4.00 mm (0.1575-inch) shank diameter. It is a single-piece, right-hand cutting tool suited for residential, commercial, and light industrial service work where a compact, standard-length drill is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction for general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003e118-degree radial point for self-centering entry on common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web design reduces thrust and improves penetration\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup to affect diameter tolerance\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute promotes efficient chip clearance in through-hole and blind-hole drilling\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 specification for consistent jobber-length geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 338 jobber-length replacement drill bit for use in any standard drill chuck accepting a 4.00 mm straight cylindrical shank, appropriate for aluminum, non-ferrous metals, and general-purpose workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance professionals using a drill press, mill, or handheld power drill with a compatible chuck. Secure the straight shank fully in the chuck before operation and verify chuck key removal before starting the spindle. Use appropriate cutting fluid or lubrication when drilling ferrous or harder non-ferrous materials to extend tool life. Inspect the cutting edges for wear or chipping before each use and replace the bit if point geometry is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.00 mm (0.1575 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 75.00 mm (2.9528 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 43.00 mm (1.6929 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm (0.1575 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 32.00 mm (1.2598 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Radial\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\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: Aluminum and Non-Ferrous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 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\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.012 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: 45271\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51735520575794,"sku":"45271","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/edb75aa4848fb05c9d6ac7dd3502f4ea.jpg?v=1788772839","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-45271-jobber-drill-bit-4-00-mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
