Manufactured from high speed steel with a bright uncoated finish, it features a standard 118-degree split point with web thinning for improved penetration and reduced walking on entry. The two-flute spiral design with a regular spiral type promotes efficient chip evacuation. At 2.375 inches overall length with a 1.375-inch flute length, this bit fits standard drill chucks and is built to Series 150D specifications conforming to DIN 338. It is suited for general-purpose drilling in production and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis bit is designed for drilling non-ferrous metals and other general-purpose materials where a small-diameter, wire gauge drill is required. The straight cylindrical shank seats cleanly in keyed or keyless chucks on benchtop drill presses, hand drills, and CNC drill heads. The web-thinned, tapered web geometry reduces thrust requirements, making it practical for close-tolerance work on thin stock or where breakout control matters. Machinists, maintenance technicians, and fabricators working with aluminum, brass, copper, and similar materials will find this a standard stock bit for everyday production drilling tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 39, decimal diameter 0.0995 inches\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with bright uncoated finish\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web thinning for easier entry\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral design for consistent chip clearance\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank, 1.0 inch shank length, 0.0995-inch shank diameter\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 338 standard; Series 150D general purpose grade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose OEM-style jobber length drill bit compatible with any standard drill chuck accepting a 0.0995-inch straight cylindrical shank, suitable for benchtop drill presses, hand drills, and CNC drilling equipment used on non-ferrous and general-purpose workpiece materials.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall the shank fully into a properly sized drill chuck and verify it is firmly secured before operation. Power down and disconnect the drill or machine before changing bits. Use appropriate cutting fluid or lubricant when drilling non-ferrous metals to extend bit life and improve hole quality. Inspect the cutting edges for wear or chipping before each use, as small-diameter bits are susceptible to breakage under side load or excessive feed pressure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 39\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0995 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: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0995 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0 inch\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\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\u003eWeight\u003c\/strong\u003e: 0.0045 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 44309\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51738619314482,"sku":"44309","price":29.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c0ead23e240e368f73fd04349c7f18c9.jpg?v=1788801864","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-44309-jobber-drill-bit-wire-39-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
