Part of the 150D Series, this bit features a 118-degree standard point angle, a two-flute regular spiral configuration, and a web-thinned tapered web for improved chip evacuation and reduced thrust during entry. Overall length is 3.75 inches with a 2.5-inch flute length. The straight-cylindrical shank measures 0.2090 inch in diameter and 1.25 inches in length. It is suited for general-purpose drilling in non-ferrous metals and is installed by machinists, maintenance technicians, and trade professionals working with standard drill chucks.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for general-purpose drilling operations in non-ferrous metal workpieces such as aluminum, brass, and copper. The 150D Series jobber length format fits the widest range of bench drills, hand drills, and drill presses found in HVAC, plumbing, and electrical trade work, as well as light manufacturing and maintenance applications. The bright uncoated finish is appropriate for lower-heat, general-purpose use rather than high-speed production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 4 wire size, 0.2090 inch decimal diameter for precise sizing in standard drill charts\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry on non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces thrust and improves chip clearance\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability across a broad range of general-purpose materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for lower-temperature drilling applications\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 standard for jobber length drill 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 any standard drill chuck accepting a 0.2090-inch straight-cylindrical shank, including bench drill presses, cordless drills, and pneumatic drills used in trade and maintenance applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the straight-cylindrical shank firmly in a keyed or keyless chuck before operation and verify chuck capacity accommodates a 0.2090-inch shank. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Use appropriate cutting fluid or lubrication when drilling non-ferrous metals to extend bit life and improve hole quality. Inspect the cutting edges for wear before each use and replace the bit if the point shows chipping or rounding.\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: No. 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2090 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2090 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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\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\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inch\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: 0.0273 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: 44274\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51744524435762,"sku":"44274","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f1df91ee1263a2cca3d7268cc1fa0161.jpg?v=1788857539","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-44274-no-4-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
